Why a 3800 supercharged swap? First, it's FUN and has mind boggling acceleration from a stop. Also it's simple, easy due to this guide (I will answer questions here too), off the shelf, easy to find engines, has aftermarket support, parts are sill produced, affordable (~$3000-3500 min), very reliable, small/fits better than the stock 2.8, has many transmission options with a strong stock 4spd auto, and takes you from 85/135chp to at least 235chp and easily 280+chp (~13 second 1/4 mile) with few easy DIY mods (up to ~400hp with the factory supercharger and ~600hp on stock internals).

Do not blindly follow this guide and buy parts until you feel you understand for yourself why and how everything about a 3800 engine works. This build thread is NOT BASED ON THE FACTORY INSTRUCTION MANUAL, but rather years of accumulated modification knowledge from across many companies, personal experience, and the internet. It might be helpful for you to buy a Buick 3800s factory service manual.

That's a great list of parts however I think it's a bit misleading. Their are many different ways to do the 3800 swap depending on your abilities and finances. Honestly looking over your list I don''t think I used a single part from it to do any of my swaps.

How to pick out parts for your build: 3800 Performance and Specs of historical swaps
All options for your engine swap will come down to cost and effort. Use the charts and videos below to decide what power you want out and how much effort and money you are willing to invest into the project. 3800 engine modifications are labeled as "Optional" in build 1; and build 2 is completely optional (some needed if you start with a Series III engine).

-----Modification Selection Chart-----
The below chart shows most camshaft options for a 3800 available, the dyno wheel horsepower numbers for 3800 builds across the internet, and quarter mile track times for 3800 builds across the internet as of 2018. The chart shows the modifications for each person's setup (camshafts, superchargers, cylinder heads, fuel type, boost, compression, etc.). Generally, red colored cells indicate either bad performance or hard to achieve (expensive or lots of other supporting mods required),

-----Differences between 3800 Engines-----
There are many variations of 3800 engines. There are 3 different series, supercharged and non-supercharged (NA). Virtually every engine has a different wiring harness and different parts between years, makes, and models.
The ideal donor car or motor to buy is a 1998-2002 Pontiac Grand Prix GTP. If you do not get an engine from a GTP, there are many parts listed in build 1 that you will need in addition, just to make it fit in a Fiero.

Read up:
https://en.wikipedia.org/wiki/Buick_V6_engine

NOTE: DO NOT SWAP A SUPERCHARGER ONTO A 3800 NA (Naturally Aspirated) BLOCK UNLESS YOU KNOW EXACTLY WHAT YOU ARE DOING. THE COMPRESSION, PISTONS, AND RINGS ARE DIFFERENT.

-----Transmission Options-----
NOTE: Many transmissions will work with this car. Here are a few common ones that can handle the 3800 power. See more in build 1 TRANSMISSIONS section.
http://www.fastfieros.com/t...06_transmissions.htm
4t60e 4 speed auto (comes with 3800s) - will only withstand ~200hp - https://en.wikipedia.org/wi..._transmission#4T60-E
4t65e 4 speed auto (comes with 3800s)- will only withstand ~250hp - https://en.wikipedia.org/wi..._transmission#4T65-E
4t65e-HD 4 speed auto (comes with 3800sc) - will withstand ~300hp, and up to ~350hp with modifications - already comes on 3800sc cars. EASIEST TO USE - https://en.wikipedia.org/wi...ransmission#4T65E-HD
Getrag 282 5 speed manual (stock Fiero) - will only withstand ~250hp - https://en.wikipedia.org/wi...rag_282_transmission
Other Fiero Manual Transmissions (stock Fiero) - will only withstand ~200hp - https://en.wikipedia.org//w...Pontiac_Fiero#Manual
4t80e 4 speed auto (not covered in this guide, see note below) - will withstand ~400hp but is big and heavy - https://en.wikipedia.org/wiki/GM_4T80_transmission
NOTE: See this video on installing a 4T80 into a GTP - https://www.youtube.com/wat...kff2RlPWB_O&index=71 and this video - https://www.youtube.com/wat...&index=9&pp=gAQBiAQB
F23 5 speed manual - will allegedly withstand ~500hp (not covered in this guide, see note below) - https://en.wikipedia.org/wi...rag_F23_transmission
F40 6 speed manual - will allegedly withstand ~600hp (not covered in this guide, see note below) - https://en.wikipedia.org/wiki/GM_F40_transmission

-----M90 Gen 3 and Gen 5 supercharger specs-----
Relevant M90 Supercharger Design and Performance Information:
http://www.mscperformance.com/specpg2.html
Alternatively I copied the data from the above link to this post: https://www.fiero.nl/forum/...HTML/139530.html#p14

Here is a quote from Eaton about the performance of an M90 Gen 5 supercharger compared with a Gen 3 supercharger:
The 90-cubic inch Gen V supercharger is very compact. Its housing includes the throttle-body adaptor, crankcase ventilation plumbing, coolant passages, the evaporative emissions purge valve and the rotor drive mechanism. The drive mechanism is sealed and permanently lubricated, obviating the need for oil connections and eliminating a potential source of leaks. Moreover, the Gen V features all-cast components and a larger, low-restriction outlet port. The tuned inlet port is also less restrictive, compared to previous-generation superchargers, allowing a larger (75 millimeter) throttle body. As a result, more air is pumped by the supercharger through the Series III’s induction system. The Gen V’s rotor is finished with Abraidbable Powder Coating (APC) rather than epoxy. APC is a patented material containing graphite that is electrostatically applied to the rotor and baked on. As a result, the rotor requires less clearance within the supercharger housing, resulting in less leakage around its edges, greater airflow at a given operating speed and lower operating temperature. The Gen V’s rotor bearings have been enlarged to increase durability and reduce operating noise and vibration. As a result, the Gen V operates at considerably higher efficiency than its predecessors. At wide open throttle, the Gen V turns at 700 fewer rpm (a 9 percent reduction), draws 13 percent less power from the crankshaft, decreases operating temperature 15 percent and increases volumetric efficiency 9 percent. For the customer, that means a 9 percent increase in horsepower (see product specifications), and best-in-class acceleration times for the Grand Prix.

Thanks for your time and contribution to the cause!!

Everyone's build will vary for sure depending on wants and needs, however for you to go through the trouble and list what worked for you is greatly appreciated. Thank you. It will, at the very least, give people an idea on what to expect and look for.

[This message has been edited by Spadesluck (edited 03-26-2017).]

BUILD 1: A COMPLETE BUDGET 3800 FIERO SWAP AND/OR 3800 REPAIR GUIDE
CLICK TO VIEW MOST OF BUILD 1 ON AMAZON
CLICK HERE TO VIEW MY EBAY STOREFRONT WITH LISTS OF MANY OF THESE PARTS
CLICK HERE FOR A PRICING GUIDE AND A CUSTOMIZABLE BUILD SHEET (maintained infrequently)
NOTE: THIS BUILD 1 LIST IS COMPLETE AND INDEPENDENT OF BUILD 2, BUT BUILD 2 INCLUDES THIS BUILD 1 LIST UNLESS NOTED!

NOTE: The ideal donor car or motor to buy is a 1998-2002 Pontiac Grand Prix GTP or Regal. If you do not get an engine from a GTP or Regal, there are many parts listed below that you will need in addition to make it fit in a Fiero.

Preface: The output of this engine is expected 280 crank horsepower with optional easy, minor modifications. Those modifications are:
-3.4" supercharger pulley - for slightly increased air
-180 degree thermostat - for slightly cooler combustion
-Tune the computer (delete VATS security, increase shift speed, increase torque limiter, delete ABS, radiator fan setpoints, adjust fuel, MAF calibration, timing, check local laws before disabling EGR/Rear O2 Sensor etc.) (ECU/PCM)
-Autolite 104 Spark Plugs (2 heat range colder than stock spark plugs) - for slightly higher knock resistance

This build thread also assumes you optionally DELETE the following:
-Swap the valve covers so that the oil fill cap is on the other side so it is accessible from the Fiero engine bay.
-"Coffee can" vacuum accumulator canister for stock cruise control - stock Fiero cruise control allegedly works by hooking the vacuum line directly to the supercharger port, since the 3800 has more vacuum than the stock Fiero engine.
-Fiero vacuum lines except brake booster and cruise control (unless deleting cruise or switching to the 3800 cruise control module)
-Alternator bracket/coolant circuit (relocated and cooling circuit bypassed)
-Power Steering Pump
-Optional: Stock Fiero intake - requires new intake mounted.
-Optional (check local laws): EGR system - requires welding and sealing shut holes in exhaust and lower intake manifold, detailed in build 2. Requires reprogramming the computer to delete EGR codes and functionality.
-Optional (check local laws): Catalytic Converter and Rear O2 Sensor. Requires programming the computer and deleting rear O2 sensor codes and functionality.
-Optional (check local laws): EVAP System/vacuum lines - requires plugging supercharger hole with freeze plug and JB weld, reprogramming the computer, plug the extra EVAP hose on the fuel tank header, and venting the gas tank cap (You can easily do this by removing the valve in the gas tank filler cap.)

You can swap this build in less than 1 month and expect a 13-13.5 second quarter mile and a 1.9 60' time without modifying the tune.

THE LIST:
The numbers in (x) are the quantity of parts you need to order.

-----PARTS YOU NEED TO TAKE OFF THE DONOR CAR-----
-Engine
-Map Sensor Vacuum Lines
-Transmission (optional; bolted to engine anyways)
-Wiring Harness up to the Firewall + OBD II Connector from inside the car (cut the wires) + Fiero Wiring Harness
-Computer
-A/C Hose up to the firewall
-3" Exhaust flange (cut it off from the car side)
-Extra fuses and relays from the fuse box
-Power washer fluid pump, tank, and hoses if you want some cheap methanol injection (not covered in this guide)
-Electronic Cruise Control Module and Cruise Cable
-Both CV front axles (from a GTP, others may or may not work)

Optional: 3.4" Supercharger Modular Pulley System (1x):
ZZPerformance 3.4 MPS - https://ebay.us/aTa3fF
Alternate - Smoothflow 3.4 Polished Finish Pulley System MPS (Modular Pulley System) - http://www.smoothflowpulleys.com/3800_MPS.html
NOTE: DON'T JUST ORDER A BARE PULLEY! ORDER THE PULLEY SYSTEM WITH THE HUB THAT IS PRESSED ON TO THE SUPERCHARGER SHAFT!
NOTE: It is not recommended going smaller than a 3.4" pulley on a stock setup without more modifications to the engine first. See BUILD 2.

Optional: Supercharger Pulley Puller (1x):
https://ebay.us/aQacLX
NOTE: Re-installing the pulley can be difficult. Put an ice bag on the shaft and the new pulley hub in the oven and used a hammer and a block of wood to pound it on. There may be better tools for this installation.
NOTE: You can rent something like this from autoparts stores but they usually do not fit right.

Optional: Flexible air duct flex 4" dia, 41inch long, to replace stock Fiero/3800 air intakes(1x):
Spectre SPE-9751 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
Note: This is a very easy fitting universal intake hose. See alternatives below for more ideas.
REPLACED IN BUILD 2
Alternative: Walker 42423 4" dia INSIDE, 18" long (1x): https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
Alternative: Walker 43381 4" dia INSIDE, 36" long (1x): https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

Optional: Air filter (1x):
K&N RE-1040 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: This entirely replaces the stock air intake and water separator. Air filter is fastened under fender well behind drivers' seat and behind the stock intake vent. This is the BIGGEST filter that I can fit behind the side intake scoop.

Optional: Air filter wrap for above filter (1x):
FILTERWEARS K298K - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: Keeps water out and your filter clean. Your filter gets VERY DIRTY in wet weather without one. See filter wrap size chart: https://www.knfilters.com/search/wrap

Optional: 1.9 Rockers (1x):
https://ebay.us/kpeqbM
NOTE: NOT COMPATIBLE WITH ANY AFTERMARKET CAMSHAFT!!!! If you want some decent performance gains (5-7%) with minimal effort, these quite literally bolt on to the engine. Might be a good idea to replace valve springs if the engine is over 100,000 miles (see build 2).

Valve cover seals (1x):
Ultra-Power VS50465R - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
Note: These wear out, consider replacing them to avoid an oil leak.

-----FUEL-----
NOTE: Larry Curchoe will build and sell you a fuel system (may be more applicable to BUILD 2) - https://www.facebook.com/larry.curchoe/
NOTE: This setup below connects directly to the 3800 stock fuel rails and the stock Fiero lines.
NOTE: FOR COMPLETE E-85/Ethanol CONVERSION and custom fuel rail setup, SEE BUILD 2. This list replaces all Fiero hoses to allow for running ethanol, since most states have up to 15% ethanol in all fuel now.
NOTE: Check out how to modify Series III/Gen 5 rails for a Series II/Gen 3 - https://www.gmtuners.com/fiero/returnless.htm

Fuel pump (1x):
Walbro 255 LPH F20000169 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
Alternate (quieter): Quantum 255 LPH HFP-343 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: BE CAREFUL WITH THE QUANTUM PUMPS. THE INLET CAN BE CLOSE TO THE BOTTOM OF THE FUEL TANK AND SUCKED AGAINST THE TANK, NOT ALLOWING FOR FUEL FLOW AT HIGH FUEL DEMANDS. TRIM THE BOTTOM LIP OFF OF THIS FUEL PUMP TO GIVE MORE CLEARANCE FOR DRAWING FUEL FROM THE BOTTOM OF THE TANK, WHILE STILL ALLOWING ROOM FOR THE SCREEN TO FIT - REMOVE SCREEN BEFORE TRIMMING.
NOTE: The 3800sc requires slightly more fuel than the stock Fiero pump can put out. You might be able to get by without changing this if you do not modify the 3800sc at all. It can always be changed later, as the tank can be pulled separately.
NOTE: SEE BUILD 2 FOR E85 CONVERSION. YOU WIILL NEED A 340+ LPH PUMP INSTEAD!
NOTE: Many fuel pumps out there are FAKES. Buy directly from the manufacturer's website or from this post.
REPLACED IN BUILD 2

Fuel tank lock ring and seal (1x):
Dorman 579-001 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

-----EXHAUST-----
NOTE: This exhaust system mates to the stock 3800 exhaust headers, which allegedly can support up to 300hp. You will have to custom-weld your exhaust. There is no bolt-on exhaust for an engine swap (does someone want to start making these?). Final fitment can vary between year models of Fieros, engine mounts, etc. Go to an exhaust shop and get one welded up after the engine is in the car.
NOTE: The best pipes are mandrel bent stainless steel.

-----COOLANT AND HOSES-----
SEE DIAGRAM BELOW FOR PART #s
NOTE: THE BELOW DIAGRAM AND PART #s RELATED TO THE HEATER HOSE ONLY WORK FOR AN 87-88 FIERO. YOU WILL NEED A DIFFERENT HEATER HOSE FOR OTHER MODELS. TRY GETTING A T FITTING LIKE THE BUILT IN STYLE FOR 87-88 FIEROS.
NOTE: See this video on cooling system modifications. https://www.youtube.com/wat...kff2RlPWB_O&index=34

1 - 3800 Thermostat housing to drivers' side coolant hose 1.25" to 1.25" (1x):
Dayco 71082 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: Cut a few inches off the end(s). Duralast E71082 also works.

2 / 3 - Radiator filler neck 1.25" inlet and 1.25" outlet (1x):
HCHCSPEED ‎JP2826-SL - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: To fill coolant. Plug the overflow nipple. There are many other ways to do this.
NOTE: To Avoid buying a ridiculously expensive custom thermostat housing (https://westcoastfiero.com/...l-thermostat-housing) or to avoid making a new one. If you go the modified 3800/fiero thermostat housing route, it may work better for routing your heater core lines on an 84-86 Fiero instead of into the 3800 Lower Intake Manifold or instead of into the 3800 coolant inlet on the right side of the diagram below.

4 - 3800 Water pump 1.5" to Passengers' Fiero coolant hose 1.25" (1x):
Gates 21205 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: Cut a few inches off the small end. DAYCO 71126 also works.

5 - Barb coupling for below heater hose to stock Fiero heater hose 5/8-5/8" ID (1-2x):
ICT Billet ‎AN627-10A - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: Instead you could optionally use a barb ball valve shutoff for shutting off hot coolant circulation to the cabin of the car during the summer: Sharkbite 22462LFA - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

6 - Heater Hose (1x):
1987-1988 Continental 63113 - https://ebay.us/BtMRNa | https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl or DAYCO C87641 - https://www.autozone.com/co...641&redirectUrl=true
NOTE: This works well for 87-88 Fieros; earlier Fieros may need a longer heater hose to the firewall and a T in the return coolant pipe similar to an 87-88. Goes with the 5/8" barb above; you'll have to fabricate and mount a retaining bracket detailed in LostNotForgotton's Video
NOTE: The 7/8" 3800sc heater hose elbow can squeeze on to 5/8" stock 87-88 Fiero heater hose line
OR
1984-1986 TBD



NOTE: Instead of fabricating a retainer bracket in the video above, some choose to tap the coolant hole in the lower intake manifold with threads and put a pipe 3/4 MNPT to 3/4" OD barb fitting in, and a 5/8 ID molded hose with a right angle, and a 3/4" OD Barb fitting to join to the stock Fiero hose. I do not recommend as the hole is undersized for the proper sized tap and would ideally be honed out/drilled larger before a proper tap can fit with with a 59/64 drill bit, however this process is prone to cracking the aluminum intake to be potentially irreparable:
NPT tap set (1x): Drill America POUCSNPT5 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
3/4 MNPT to 3/4" OD barb fitting (1x): Sharkbite ‎UC134LFA - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
5/8 ID molded hose with a right angle (1x): Gates 28467 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
59/64 drill bit (1x): Drill America DWDRSD59/64 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: You may want to buy other large drill bits in steps leading up to a 59/64" so you can drill out the heater hose coolant port in steps. Again, I do NOT recommend drilling for risk of cracking.

7 - Aluminum Heater Hose Elbow (1x):
Dorman 47065HP - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: These CRACK if they are plastic! REPLACE with aluminum above!

OR
Motorad Failsafe 723-9180 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: Motorad thermostats with a small hole like the may be easier to burp the system but could cause longer warm up, P0128 code, & slight warm up power loss.

9 - 1" expansion frost plug for plugging water pump hole that used to go to the alternator coolant circuit (1x):

NOTE: May be difficult to install the oil pressure sensor above with the FieroRog alternator relocator bracket installed. This should help with relocating that. I am not sure this exact part will give enough clearance for the oil sensor (may be pinned against the oil filter housing)

-----NEEDED IF BUILDING YOUR OWN HARNESS-----

Spec 3+ Clutch (1x):
First, choose your clutch type and your transmission donor car here: https://specclutch.com/products/
Then, punch in the part # here: https://ebay.us/Ax6J60
Below are common ones for swaps.
1985-1988 2.8L Fiero 5spd - Spec SC883F
1985-1988 2.5L Fiero - Spec SC783F
1984 2.5L 4spd / 1985-1987 2.8L Fiero 4spd - Spec SC773F
NOTE: For manuals, (F23, F40, Getrag, etc.) everyone seems to use a Spec 3+ clutch, however sometimes Spec sends the wrong clutch. It must be MATCHED for your specific manual transmission; not any one will do and you can NOT order them online from what I understand. And sometimes even Spec puts the wrong clutch in the box. Best to call them up and verify your exact application first. Your clutch may rub the transmission if they get it wrong.

NOTE: For extra safety to pick up metal shavings in the oil.

Optional: AC/DRYER (1x):
Four Seasons 33181 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

Optional: Custom A/C hose made by a radiator shop (1x):
Larry Hubbert makes hoses - https://www.facebook.com/larry.hubbert.77/
Chuck Peterson makes hoses - https://www.facebook.com/chuck.peterson.566 or https://www.fiero.nl/forum/Forum4/HTML/069681.html
James L. Brown makes hoses - https://www.facebook.com/Fiero3800harnesses/
NOTE: To build your own, see LostNotForgotton's video - https://youtu.be/ZyPZkCPJzN...qJnkff2RlPWB_O&t=530
NOTE: Have a radiator shop make one. You need an R12 style port for the AC Pressure sensor. Cut one off of another 3800 AC hose and have it braised onto the Fiero side. Also use a GTP compressor side AC hose fitting for the compressor that came with the GTP. Beware, there were at least 2 types of compressors/AC hoses on 3800 engines.
NOTE: Joe Norton used to make A/C hoses but has stopped production.

Optional: R134a AC Seals (3800 side) (1x):
Four Seasons 26728 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

Optional: R134a AC Seals (Fiero Side) (1x):
Four Seasons 26735 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: If you do want to utilize the AC system, you will need to charge it with R134a or newer refrigerant. The Fiero did not come equipped with this, so you will need to swap all your AC System O-Rings with Hydrogenated Nitrile (HNBR), and your orifice tube.

Optional: R134a AC Orifice Tube (1x):
ACDELCO 15-5754 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

Longer 45" battery ground cable (1x):
Schumacher BAF-445S - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

Alternator (1x):
ACDELCO 335-1088 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: You need a year 2000+ alternator for any 3800 car to fit with FieroRog alternator bracket. This is the highest current (125A) model made; relocating the alternator without the cooling circuit can make a lower current alternator struggle to keep up. Your donor car may have this already; the bigger cars (park avenue, bonneville) have higher current alternators already. Do NOT get an off brand and/or remanufactured alternator; they tend to be junk.

Optional: Alternator voltage boost circuit (1x):
https://zzperformance.com/p...ator-voltage-booster
OR
https://easyperformance.com...ltage-booster-module
NOTE: The relocated alternator does not get cooled. It looses efficiency and does not charge as well. This boost circuit may help with that by increasing the alternator voltage by 0.6 Volts. You can do this for free here: https://zzperformance.com/b..._sid=0a5a8d6d2&_ss=r

Optional: A/C Compressor Bypass Pulley (1x):
Dorman 34195 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: Bypasses the AC Compressor if not using AC to save some horsepower and weight.

-----MOUNTING AND BRACKETS-----
NOTE: This build uses FieroRog brackets. There are alternatives (like West Coast Fiero). You could build your own, but some parts in this build thread may not fit those if the transmission does not stay in the stock location.
NOTE: For Fiero manuals, you do not need cradle side transmission mounts, although you may want to replace the old rubber anyways.
NOTE: Rodney Dickman poly motor and transmission mounts are now discontinued, but they were located here. Poly motor mounts and a deleted balance shaft may make the car vibrate badly. V6 POLY ENGINE MOUNTS THESE ARE NOW BEING MADE HERE: https://fierospace.com/prod...6-front-engine-mount
NOTE: James L. Brown - https://www.facebook.com/Fiero3800harnesses/ is now producing poly mounts again.
NOTE: The 1988 Rodney Dickman engine cradle mount does not quite fit the FieroRog engine bracket right on some applications. May require drilling some ~1/2" offset holes. MAY IMPACT AXLE LENGTH REQUIREMENTS. Earlier year Fiero cradle/mount combinations may work better.

Optional: Adjustable Dogbone Mount - bolts to FieroRog alternator relocation bracket (1x):
http://rodneydickman.com/pr...o.php?products_id=72
OR
http://rodneydickman.com/pr....php?products_id=226
NOTE: I do NOT Recommend a solid mount for vibration.

Rear Frame Floating Cradle Nut Kit (1x):
http://rodneydickman.com/pr....php?products_id=276
NOTE: It is CERTAIN that the original nuts for the rear cradle will snap off the frame. You may have to cut a slot in the frame to get them out. Use 2 pairs of big vise grips to grab the nut through the cut hole in the frame in order to torque against it. The nut kit above sits inside the frame so in case the welds break loose next time, the mount is long enough that it can torque against the frame.
NOTE: This may be discontinued. It is not hard to weld a nut to a long drilled piece of steel yourself.

See the options available here for shorter, over bore, etc.: INTENSE HGP-0xx - http://www.intense-racing.com/PROD/HGP-0xx.html
NOTE: Pistons should measure out of cylinder hole ~0.025". You want .038"-.046" of quench according to INTENSE racing. For 0.035" quench + 0.025" out of hole = 0.060" thick gasket 0.04 extra compression and slightly more power.
NOTE: The arrow and the "L," or Left-Hand Side (LHS) gasket goes on the cylinder 1/3/5 side of the engine (towards the Fiero firewall, away from the donor car firewall). If you look at the rear cover from the rear of the engine, it goes on the left hand side.
NOTE: Your decks and heads must be perfectly flat and clean to install these MLS gaskets. Consider decking your surfaces, detailed in the Assembly videos section build 2. Otherwise they may leak.
NOTE: MLS should be reusable (unless heat cycled), and is not messy to clean off.
NOTE: Cometic indicated they have black Viton seal coating on the MLS gaskets and you should NOT use a copper spray on these. INTENSE racing says they do use copper spray. It is difficult sealing the coolant passages with these without a copper spray.

I have my engine (3800 SC) out of a 2002 Grand Prix 40th Ann. so I'll be watching VERY close for those vids...

[This message has been edited by bulldog85043 (edited 11-12-2017).]

BUILD 2: A COMPLETE PARTS LIST FOR AN ALL-OUT 3800 BUILD (build 1 also needed if you are doing a Fiero swap)

THIS BUILD IS IN ADDITION TO BUILD 1, MEANING YOU MUST ORDER ALL OF BUILD 1 PARTS TOO, UNLESS SPECIFICALLY MARKED OTHERWISE

CLICK TO VIEW MOST OF BUILD 2 ON AMAZON
CLICK HERE TO VIEW MY EBAY STOREFRONT WITH LISTS OF MANY OF THESE PARTS

CLICK HERE FOR A PRICING GUIDE AND A CUSTOMIZABLE BUILD SHEET (maintained infrequently)

NOTE: THIS BUILD IS TO MAXIMIZE THE POWER OF YOUR M90 3800 AT A HIGH RPM WITH THE ZZP XPZ CAMSHAFT. CONSIDER DOING YOUR OWN RESEARCH INTO A LOWER RPM CAMSHAFT/VALVETRAIN AND AVOID A TIMING CHAIN/BALANCE SHAFT REMOVAL AND MACHINING CYLINDER HEAD VALVE GUIDES. MAYBE ONLY PUT 1.9 RATIO ROCKERS ON WITH A STOCK CAMSHAFT, OR TRY A ZZP VS OR XP CAMSHAFT FOR GOOD PERFORMANCE GAINS WITH MINIMAL EFFORT.

NOTE: IF YOU REMOVE YOUR CRANKSHAFT, TIMING CHAIN, CRANK POSITION SENSOR, AND/OR CAMSHAFT, YOU MAY NEED TO PERFORM A CRANKSHAFT POSITION LEARN IN THE TUNE. SEE THIS VIDEO: https://www.youtube.com/wat...kff2RlPWB_O&index=35

NOTE: THIS BUILD IS MATCHED FOR A ZZP XPZ CAMSHAFT. NOTES INDICATE WHAT PARTS ARE REQUIRED FOR THIS CAMSHAFT.

NOTE: IF YOU INSTALL A NEW CAMSHAFT, LIFTERS, ROCKERS, BEARINGS, RODS, RINGS, OR PISTONS, ETC., YOU MUST BREAK-IN YOUR ENGINE. USE BREAK-IN OIL ADDITIVE AND DO NOT REV YOUR CAR MORE THAN ~4,000 RPM FOR THE FIRST ~1,500 MILES!

NOTE: THIS BUILD ASSUMES YOU DELETE the balance shaft/tensioner spring/balance shaft gear (to fit the double roller timing chain), detailed here: https://www.youtube.com/wat...kff2RlPWB_O&index=51

This list assumes you buy a Series II engine and convert to a Series III supercharger. It would be easier to buy a Series III to begin with.

THE LIST:
The numbers in (x) are the quantity of parts you need to order.

-----Air-----
For turbo guys, check these out:
Intake manifold from a 1995-1998 Camaro/Firebird (1x): GM 24505489(?) - https://ebay.us/247eyG or GM 24505487 - https://ebay.us/kmUCH3 or GM 24504806 - https://ebay.us/rBlksV
NOTE: It would be difficult to use a 99-02 Camaro/Firebird intake (GM 24505923 / GM 24505921) because it is drive by wire and the inlet is angled in a poor direction.
Intake Manifold Gasket (1x): Fel-Pro MS 95794 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
Turbo Camshaft (1x): https://zzperformance.com/p..._sid=4b3e1dde6&_ss=r

DUPLICATES BUILD 1

Optional: Longer Supercharger Bolts for upgrading from Series II / Gen 3 to a Series III / Gen 5 (1x of each):
Re-use all GEN 3 Supercharger bolts, but in addition:
M8x1.25x120mm bolt (1x): uxcell A15060500ux0101 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
M8x1.25x140mm bolt (1x): uxcell ‎A17110600ux0679 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
OR
M8x1.25 Threaded Rod (1x 2-pack): https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
M8x1.25 Nuts (1x 5-pack): Eastlo IN10050106-25 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: See supercharger upgrade instructions in Assembly Diagrams section - https://www.fiero.nl/forum/.../HTML/139530.html#p9
NOTE: Longer Bolts are included with intercooler and phenolic spacer kits, so you would not need these bolts.

Optional: 2.8" Supercharger Pulley (1x):
ZZPerformance 2.8 MPS - https://ebay.us/HxwDF4
NOTE: ZZP only guarantees a 2.8" pulley fits on all superchargers, but it is possible to go smaller in some cases (2.7, etc.) without machining.
NOTE: The smallest pulley ZZP offers is a 2.55" pulley after machining down the snout (see below): https://ebay.us/CXKc45
NOTE: If you go below 2.8", it is required to machine down the supercharger snout with a machining tool here: https://ebay.us/URtLzN. INTENSE Racing suggests this is pointless, as smaller pulleys beyond this point make exponentially increased temperature from compressed air.
NOTE: Instead of a smaller than a 2.8" supercharger pulley, consider a 5% overdrive balancer pulley detailed in later in this post. Dayco PBO81461SC5 (1x): https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
REPLACES BUILD 1

Optional 1" ZZP Phenolic Spacer (1x):
Gen 5 Supercharger - https://zzperformance.com/p.../m90-phenolic-spacer
OR
Gen 3 Supercharger https://zzperformance.com/p...riant=12623054930031
NOTE: NOT COMPATIBLE WITH INTERCOOLER (unless you want to punch a big hole in your decklid), instead opt for a 1/4" phenolic spacers if you intercool
NOTE: You will need around a 1.5" longer supercharger belt to support https://www.rockauto.com/en...h/?partnum=6k6%2A%2A

-----Intercooling-----
Note: See install video here: https://www.youtube.com/wat...kff2RlPWB_O&index=75
NOTE: See other sections for redundant wire, wiring tools, hose clamps, fuel injector o-rings, custom fuel rails (required), NPT Tap set, gray gasket maker, antifreeze, spade connectors, tools, etc. OR see video description or amazon list:
CLICK HERE TO SEE INTERCOOLING LIST ON AMAZON
NOTE: IN ADDITION TO THIS SECTION, YOU NEED CUSTOM FUEL RAILS. SEE "Fuel rails, hoses, regulator, and fittings" SECTION OF build 2

Optional: Intercooler Kit (1x):
ZZP Stage 2.5:
Gen 5 supercharger - https://ebay.us/HWxShY
Gen 3 supercharger - https://ebay.us/KNkzse
OR
ZZP Short Stack:
Gen 5 supercharger - https://ebay.us/avvZgM
Gen 3 supercharger - https://ebay.us/dtriFM
NOTE: You will need around a 2.5" longer supercharger belt to support a full stack and a 1.5" longer belt to support a short stack https://www.rockauto.com/en...h/?partnum=6k6%2A%2A
NOTE: Full stack will need cutting into decklid to fit supercharger snout, pairs nicely with a 1/4" phenolic spacer
NOTE: Dual pass heat exchanger puts the hoses on the same side which worked for me. I do not know if it would cool any better.
NOTE: The heat exchanger in these intercooler kits WORK WELL FOR GT AERO NOSE FIEROS ONLY IF YOU MOUNT IT UNDER THE FRONT BUMPER. See heat exchangers below that will fit the non-GT (coupe/SE/2m4) nose:
24" Single Pass non-GT front mount heat exchanger (1x): https://ebay.us/V05ar1 (single pass)
24" Dual Pass non-GT front mount heat exchanger (1x): https://ebay.us/qxlte1

Optional: 1/4" Phenolic Spacer under intercooler (1x):
Gen 5 - https://zzperformance.com/p...riant=12623054995567
Gen 3 - https://zzperformance.com/p...riant=12623054864495
NOTE: Comes with two Garlock laser cut gaskets. I do not like these. For Gen 5, Instead, consider optionally getting two more Upper Intake Manifold Plenum Gaskets (above) for a total of 3: Apex AMS3735 (2x): https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: In order to maintain enough thread engagement. you may need some ~1/4"+ longer bolts than what is included in the 2.5" supercharger kit. The longest 2 bolts included in the ZZP kit are absolutely too short for the 1/4" spacer. Instead, opt for a M8x1.25 threaded rod, and cut it to about 190-195mm and put a nut on the top. Install the nut before cutting so you can run the nut over the cut threads to re-shape them, or just re-tap or file down the threads after cutting:
M8x1.25 Threaded Rod (1x 2-pack): https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
M8x1.25 Nuts (1x 5-pack): Eastlo IN10050106-25 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

https://ebay.us/TTzHME
OR
https://zzperformance.com/c...intercooler-fill-kit (cheaper, plastic)
NOTE: You really need this for the pressure cap for pressure relief.
NOTE: Plug the overflow vent nipple.

1" (3/4" ID) Heater Hose for Intercooler (30 FT+):
Gates 28412 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: The intercooler KIT sold by ZZP above already comes with one 10' length, but that is not enough for a Fiero if you are mounting the intercooler radiator in front of the regular radiator. Cut the 30' hose into two 15' lengths.

1" (3/4" ID) molded rubber hose 90° elbow (2x):
DAYCO 80411 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

DUPLICATES BUILD 1

Optional: Intake Air Temperature Sensor relocation post-supercharger (1x):
Standard Motor Products AX1 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

Optional: 37/64 Drill bit for relocating Intake Air Temperature Sensor relocation post-supercharger (1x):
Drill America KFDRSD37/64 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl (or a 9/16 can work)
NOTE: You can drill and tap your intake manifold with a 3/8" NPT tap to stick this sensor inside after the supercharger for more accurate intake air temperature readings for tuning purposes. This sensor should plug right in to your existing harness. See build 1 or below for a NPT tap set.

Intake Air Temperature (IAT) Sensor extension cable (1x):
https://zzperformance.com/p...t-exten&_ss=e&_v=1.0
NOTE: For relocating intake air temperature sensor into the lower intake manifold after the supercharger. May not be necessary depending on where you relocate it to and how long your harness is.

Intercooler Pump Relay (1x):
https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: Redundant with fuel pump relays.

Optional: Decklid Strut Kit (Passenger's ONLY) (1x): http://rodneydickman.com/pr....php?products_id=113
NOTE: Decklid shock kits ONLY if you removed torsion bars
NOTE: The driver's side decklid strut kit would interfere with the supercharger with the extra intercooler height. Instead opt for the hinge mounted decklid strut kits and shorter shocks below

Optional: Hinge mounted decklid strut kit (2x):
http://rodneydickman.com/pr....php?products_id=439
NOTE: ONLY for removed torsion bars. Double up these kits on both sides and used the old torsion bar bolt hole (M6x1x10 bolt) with a shorter shock. You flip them mounts upside down for more clearance if needed. See video https://youtu.be/fONskBO6BZ...Jnkff2RlPWB_O&t=1162

Optional: Extra short, stiffer shock (6.42" compressed/10.0" extended, 83lbs force) for hinge mounted decklid strut (2x):

NOTE: Here are some more slightly longer and lighter force shocks if needed: 5B-3345XD (6.969" compressed/10.472" extended, 65lbs force); 5B-3658XP (7.008" compressed/11.22 extended, 67lbs force)

Alignment Roll/Tension Pin Set (1x):
Glarks B09WYDZNZD - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

-----Plugging throttle body/intake manifold heater/coolant holes/EVAP/EGR on a Gen V supercharger (Check local laws)-----
NOTE: CHECK LOCAL LAWS BEFORE REMOVING THESE SYSTEMS.
NOTE: See modification here - https://youtu.be/fONskBO6BZ...qJnkff2RlPWB_O
NOTE: For EGR, JBWeld a dime in the intake manifold hole, and welded the exhaust header hole shut (check local laws)
NOTE: If you run an intercooler, it is required to block off the coolant ports that go to the throttle body, since the intercooler does not have holes drilled.

Freeze plug kit (1x):
Dorman 557-001 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: 1/2" plug with JB Weld for EVAP Delete (check local laws)
NOTE: 2x 1/4" NPT used for plugging lower intake manifold throttle body coolant ports
NOTE: 1x 1/4" NPT could be used for plugging intercooler EGR port (check local laws) in the intercooler. Not large enough to seal in intake; consider 3/8 NPT instead.
NOTE: use NPT thread tape on these.
NOTE: Plugging throttle body coolant holes is REQUIRED for intercooling.

NPT tap set (1x):
Drill America POUCSNPT5 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
DUPLICATES BUILD 1

NPT Thread Tape (1x):
https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

7/16" Drill bit (1x):
‎DEWALT DW1128 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: For 1/4" NPT Plugs

Cooling Circuit Bypass Gasket (1x):
MAHLE Original C31274 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

-----Fuel & E85 (Ethanol) Conversion-----
NOTE: See install video here: https://www.youtube.com/wat...IM_4I2qJnkff2RlPWB_O
NOTE: See most of this E85 conversion available on amazon: https://www.amazon.com/shop..._US&ref_=as_li_ss_tl
NOTE: See pipe sizes rules of thumb: https://bsiengr.com/wp-cont...e-Rules-of-Thumb.pdf

Injectors (6x or 1x 6-pack):
Series 2 - Siemens DEKA EV1 80# Injectors - ‎110324 / FI-114992 - https://ebay.us/l9m9cz
OR
Series 3 - Siemens DEKA EV6 80# Injectors - 109991 / FI114991 - https://ebay.us/hPH7vq
NOTE: DO NOT BUY CHEAP INJECTORS ON EBAY OR AMAZON, THEY'RE FAKES. You can tell by the DEKA words on the injection molding; fakes do not have DEKA on them. If it is not around $50 per injector, it is probably a fake.
NOTE: Series III harnesses came with EV6 connectors and Series II harnesses came with EV1 connectors. Your harness provider should be able to put whichever connector on. If you end up with the wrong connectors, it is possible to get an adapter, but it will look messy (6x): https://zzperformance.com/p...riant=12623051948143
NOTE: Even if you do not use E85, you still need bigger injectors. 60# injectors would work, but it is easy to max them out on these engines. Avoid 160# injectors - they will be difficult to get to idle properly. 80# is a perfect sweet spot for the ultimate 3800sc build.

Fuel injector o-ring pack (1x):
Dorman 90100 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: These may not be required, but you always need a spare or two. The factory o-rings with these DEKA injectors seem slightly undersized for some applications. Use the thick brown o-rings from the pack.
DUPLICATES BUILD 1

Stainless Steel Fuel Sender Unit (1x):
https://www.fierostore.com/.../Detail.aspx?s=60912
NOTE: The factory sender unit reacts with ethanol and turns black and creates a corrosion layer that can come off and clog injectors. It is probably Zinc coated which is not compatible with ethanol fuel.

Optional: Ethanol Test Kit (1x):
REV X ST0501 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: When tuning, be sure to only tune for E85 (83% ethanol) so that it runs rich when "E85" sold at gas stations can legally be as low as E53.

Optional: Gauge Pod for Air to Fuel Gauge (Wideband O2) (1x):
Autometer 20100 Dual - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
OR
Autometer 20102 Single - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl
NOTE: See exhaust section in this post for AFR/Wideband O2 sensor.
NOTE: See install video https://www.youtube.com/wat...IM_4I2qJnkff2RlPWB_O

Optional: 3M Dual Lock 400 Velcro for Guage Pod (1x 3.3ft):
3M SJ3551 - https://www.amazon.com/dp/B..._US&ref_=as_li_ss_tl

-----Fuel rails, hoses, regulator, and fittings-----
NOTE: See build 1 fuel diagram and parts. The difference below is adding custom fuel rails and a fuel pressure regulator.
NOTE: The stock Fuel rails will have a hard time keeping up with high power fuel demand. This fuel rail system completely overhauls the stock 3800 fuel rail system.
NOTE: Check out how to modify Series III/Gen 5 rails for a Series II/Gen 3 - https://www.gmtuners.com/fiero/returnless.htm

Optional: You can get a custom fuel hose system made by Larry Curchoe instead of some of the below setup. https://www.facebook.com/larry.curchoe

Return Style Custom Fuel Rails (1x):

OR
See the options available here for shorter, over bore, etc.: INTENSE HGP-0xx - http://www.intense-racing.com/PROD/HGP-0xx.html
NOTE: Pistons should measure out of cylinder hole ~0.025". You want .038"-.046" of quench according to INTENSE racing. For 0.035" quench + 0.025" out of hole = 0.060" thick gasket 0.04 extra compression and slightly more power.
NOTE: The arrow and the "L," or Left-Hand Side (LHS) gasket goes on the cylinder 1/3/5 side of the engine (towards the Fiero firewall, away from the donor car firewall). If you look at the rear cover from the rear of the engine, it goes on the left hand side.
NOTE: Your decks and heads must be perfectly flat and clean to install these MLS gaskets. Consider decking your surfaces, detailed in the Assembly videos section build 2. Otherwise they may leak.
NOTE: MLS should be reusable (unless heat cycled), and is not messy to clean off.
NOTE: Cometic indicated they have black Viton seal coating on the MLS gaskets and you should NOT use a copper spray on these. INTENSE racing says they do use copper spray. It is difficult sealing the coolant passages with these without a copper spray.

-----NORTHSTAR THROTTLE BODY-----
Northstar throttle cable (see build 2 air section for parts):
NOTE: I did not hook up cruise control here. You are on your own. You can use stock cruise control if you remove vacuum accumulator canister (coffee can), plug that port from the stock vacuum accumulator canister, and plug the other port into the vacuum port on the top of the supercharger. Or, see harness section for wiring the electronic 3800 cruise module into the fiero.


-----HOW TO HOOK UP PCV-----
All you do is attach a hose from the Northstar TB nipple (before butterfly valve but after MAF) to the nipple on the supercharger by the PCV. You may need to change the direction of the nipple on the northstar throttle.The air goes from the throttle body, through the supercharger nipple, through the intake manifold, through the heads to the crank case, back up through the heads, back through the intake manifold, through the PCV valve, and back into the supercharger intake. There is no way to run a catch can without bypassing the actual PCV in some way, since it sits directly in the Gen 5 Supercharger intake.


-----EXHAUST SETUP FOR BUILD 2-----
NOTE:See build 2 Exhaust section parts list.

[This message has been edited by AustinH (edited 04-03-2025).]

I have not heard of most people re-designing the existing fuel pump circuit. I believe most have utilized the original circuit, especially the oil pressure switch and just upgraded the fuel pump fuse to a 15 amp. Some have replaced the original relay with a newer model, but the wiring has remained the same.. curtis

WIRING HARNESS AND COMPUTER/ECU/PCM PROGRAMMING
NOTE: See programming/tuning video here - https://www.youtube.com/wat...index=33&pp=gAQBiAQB
NOTE: See Fuel/Spark Tuning video here - https://www.youtube.com/wat...kff2RlPWB_O&index=35
NOTE: You need to pull the entire engine harness off of the donor car. Nothing past the firewall is needed except for the OBDII port. You do not need the headlight harness.
NOTE: If you do not have a harness, get it from a junkyard donor car at https://car-part.com/, again ideally from a 1998-2002 Pontiac Grand Prix GTP or Buick Regal. You will also need a Fiero harness, ideally 1985+.

-----Buying a harness-----
Want to buy a harness and PCM tune? I highly recommend this. Contact one of the below guys:
James L. Brown - https://www.facebook.com/Fiero3800harnesses/
Dan McIlmoyle - https://www.facebook.com/danny.mcilmoyle

-----Building a harness-----
NOTE: See programming/tuning video here - https://www.youtube.com/wat...index=33&pp=gAQBiAQB
See build 1 harness section for a parts list - https://www.fiero.nl/forum/.../HTML/139530.html#p5
NOTE: See pin and connector part numbers here: https://www.fiero.nl/forum/.../HTML/128029.html#p3

Ryan Gick (Gmtuners/Sinister Performance) will sell you a tune if you are building your own harness. - https://www.gmtuners.com/ep...2wXDLObKJDCwUtgerhpI You can also contact him here: https://www.facebook.com/pr...p?id=100080110344101
Eppler Justin will sell you a tune if you are building your own harness. - https://www.facebook.com/justin.eppler/

Want to build your own harness? Below are diagrams for doing so. This thread does not supply any wire loom dimensions for laying out the harness - that is owned by harness makers above. It is possible to simply splice all of the connections that you need and lay out your own harness routings, but this is unreliable and messy. This guide will not help with that, but it will help with the final wiring diagram.

Go to https://www.alldata.com/diy-us/en/find-vehicle and buy a subscription to your donor car's information. You can find a PCM pinout diagram of PCM Connectors C1 (Blue) and C2 (Clear) that will be critical in aiding you with building the harness.
Here are some alternative examples of pinouts from several other cars: http://www.gearhead-efi.com...98-GM-V6-PCM-pinouts

Below is an example of the PCM pinout diagram of a 2001 Bonneville SSEi. DO NOT USE THIS DIAGRAM IF YOU DID NOT BUY AN ENGINE FROM A 2001 BONNEVILLE SSEi; THEY WILL VARY SLIGHTLY!






Many great wiring harness pin out charts already exist at GMTuners: http://www.gmtuners.com/files/index.htm
Consult Gmtuners for pinout list (this guide BELOW is specifically for a 1998-2002 GTP engine and transmission harness):
http://www.gmtuners.com/fil...o_L67_PCM_wiring.pdf




Harness wiring diagram for a 1998-2002 GTP harness that works 1985-1988 Fiero with a manual transmission:
NOTE: FOR A 1984 FIERO WIRING DIAGRAM, SEE HERE: https://www.fieroinfo.com/w...4_Wiring_Harness.jpg
NOTE: The pin connector guides above are much more thorough. The diagram below bare minimum.
INSTRUCTIONS IN ADDITION TO THIS WIRING DIAGRAM BELOW:
1. For automatic harnesses:
a. Cut and ground the purple/white wire on C203 Pin R
b. Add the speedometer conversion buffer circuit shown below inline with the GTP computer connector C1 (blue) Pin 55 and the fiero C203 connector pin G
2. Change MIL (Malfunction Indicator Lamp/Engine Light) fuse to 10A
3. Change Fuel Pump Fuse to 15A or 20A
4. Change the Ignition Fuse to 20A
5. Connect C1 (Blue) connector pin 59 to pin 2 on the OBDII connector (diagram below) if you need to tune/scan your computer.
6. Wire up the 1988 Fiero Oil Pressure Gauge (on pin E of C203). Part #s in build 1 wiring harness section.


Speedometer Buffer Conversion Circuit (the input signal to the Fiero speedometer is incompatible with the 4t65e-HD transmission Vehicle Speed Sensor (VSS) output signal):
http://www.gmtuners.com/fiero/fmods.htm
NOTE: YOU MAY PURCHASE ONE OF THESE HERE: https://reddevilriver.com/h...peedo-buffer-circuit


External Transmission Range Selector Switch for a 4t60/4t65/4t65e-hd transmission:
NOTE: You will need to purchase one of these and put it on your gear selector if you did not buy a GTP. You may also need the connector for it, available at Rockauto. See above build 1 Parts List.


OBDII Connector Pinout:
NOTE: The 3800sc Fiero only uses the "VPW" configuration on pins 2, 4, 5, and 16. Connect C1 (Blue) connector pin 59 to pin 2 on the OBDII connector


Optional: 3800 Electronic Cruise Control (can instead rig up the factory Fiero vacuum cruise to work by getting rid of the vacuum accumulator coffee can and plugging the vacuum line directly into the vacuum port on top of the supercharger, then see the Assembly Diagrams Section for mounting the cruise cable)
NOTE: See cruise diagram here if you did not have cruise from the factory: http://www.gmtuners.com/fil...ise_elect_cruise.pdf
NOTE: See alternative cruise diagram here: http://www.gmtuners.com/files/electcrz.zip


Stock Fiero C500 connector in engine bay:
A good pinout is located here: http://www.nathanbittinger....roaddiction/c203c500 or here https://www.fiero.nl/forum/...421-2-096295.html#p2


Stock Fiero C203 Connector under center console


C203 and C500 connector pinouts, courtesy of http://www.gmtuners.com/files/index.htm


Optional: Fuel Pump Hot Wire, for supplying slightly more voltage to your fuel pump in high performance applications - http://www.gmtuners.com/fiero/hot_wire.htm
NOTE: If you bypass Pin B on the C203 Connector to hotwire in this way, you can re-use this wire on Pin B to permanently power the OBDII connector above.
NOTE: See build 2 for a much more in-depth hot wire.
NOTE: This diagram is much simpler than it looks. Just wire the relay pin 87 directly to the battery, the pump + directly to the relay pin 30, and pin 3 on C2 connector (Clear) to relay pin 86.

-----REMOVING AND PORTING CYLINDER HEADS-----
Video: How to disassemble cylinder heads with a valve spring compressor:
NOTE: You should drop your cylinder heads off at a machine shop, detailed later in this post. BE CAREFUL WITH THE CYLINDER HEAD DECK SURFACE. DO NOT SCRATCH THE BOTTOM OF THE HEADS. PLACE ON A LINT FREE CLOTH AND DO NOT PUT THEM ON THE GROUND OR A HARD SURFACE UNLESS YOU INTEND TO DECK THEM.
https://www.youtube.com/wat...kff2RlPWB_O&index=40


PREFACE: According to INTENSE Racing, stock cylinder heads will out-flow ANY M90 supercharged 3800 engine setup. There is virtually NO NEED to modify cylinder heads, UNLESS YOU RUN LIFT HIGHER THAN 0.525" intake/0.528" exhaust, DETEAILED BELOW.

NOTE: I would NOT attempt performing ANY of this at home. Take your cylinder heads to a machine shop. That being said, below is a collection of information about porting 3800 cylinder heads.

Here are the instructions I supplied a machine shop for porting my cylinder heads:
NOTE: Over 0.525" intake lift and 0.528" exhaust lift REQUIRES machining down valve guides. See this spreadsheet for required valve guide machining calculations - https://docs.google.com/spr...9-IzNmsOLhx3s6Z5IcjQ
NOTE: Assuming you have 1.65 rockers and not the stock 1.6 rockers
1. Machine 0.060" off top of intake valve guides to support XPZ Camshaft lift.
a. 1.65 rocker arm * 0.35375 XPZ camshaft intake lift = 0.5836875‬" total lift. Stock intake lift max is 0.525" (measure for yourself?) before intake valve runs into valve guide with stock retainers. 0.5836875"-0.525" = 0.0586875". Therefore, cut down top of valve guide by 0.060" to be safe.
2. Machine 0.030" off top of exhaust valve guides
a. 1.65 rocker arm * 0.335 XPZ camshaft exhaust lift = 0.55275" total lift. Stock exhaust lift max is 0.528" (measure for yourself?) before exhaust valve runs into valve guide with stock retainers. 0.55275"-0.528"= 0.02475". Therefore, cut down top of valve guide by 0.030" to be safe.
NOTE: LS Retainers add about 0.005" clearance, meaning max lift would be 0.530" intake / 0.533" exhaust, but to be safe this is not accounted for in my calculations.
3. Redrill and replace valve guides with Bronze oil lite guides (optional)
4. Valve job
a. widen valve seats for 1.83" intake valves (stock series 3 size; stock series 2 is 1.80"), 1.52" exhaust
b. Replace seats with hardened seats at custom 3 angle cut.
c. Back-cut valves with same 3 angle cut. Lap valves if necessary.
d. If not replacing seats with hardened seats, don't grind seat, but grind right up to it, without touching it, to maintain factory hardened seat.
5. Blend bowl smooth - remove casting mark and lips on radius
a. Street/strip port, Polish combustion chambers
b. Smooth short side radius
c. Don't drop port floor
6. Gasket Match Intake runners and Lower Intake Manifold
a. Don't gasket match exhaust. Keep the D-shape of exhaust ports (can widen a bit)
b. Polish runners
c. Blend in short side of intake
d. Be careful not to grind through walls.
7. Deck head surfaces and record thickness decked by. Need at least 50 Roughness Average (RA) on deck surface to properly seal Cometic Head Gaskets.

In addition to porting cylinder heads, on the engine block, measure each cylinder “out of hole” clearance, or the amount which a piston sticks out above the block deck when the crankshaft is at top dead center. Stock piston height should be between 0.012” to 0.025”. If the out of hole measurements for each piston are significantly different than one another, then consider decking the block. At this point, you will need to disassemble the bottom end. If re-using stock bottom end parts, keep every bolt/bearing/rod/piston/journal/cylinder matched with where it came from, including direction. Consider getting the engine inspected and blueprinted, the crankshaft ground, the rods conditioned, the rotating assembly balanced, having new oversized bearings installed afterwards, honing cylinders, and replacing piston rings with correct gap for your boost. Detailed in the next section.

This is how to properly tear down the bottom end which is not covered in this guide. Here are the instructions I would provide a machine shop with for working with the bottom-end:
If the rotating assembly is in good shape, re-use all factory items and don't recondition.
1. Measure if block needs decked. .003" out of flat and 50 microinch RA surface or more required for decking. If not leave it. If so, deck block/heads and continue.
2. Disassemble pistons/rods.
3. Keep rods, rod bolts, rod bearings, crank bearings, and journals, etc matched to each other.
4. Clean pistons and rings with oil based solvent.
5. Check rings. Leave stock rings and don't hone if rings are OK. If rings are seized:
a. Replace rings (oversized?)
b. Gap rings. Adjust gap for 12-14.5 psi roots style supercharger boost (350 deg. Max)
c. Hone cylinder bores.
d. Oil and install pistons and rings.
6. Measure rods/bearings. If good, leave stock. If rods are worn:
a. Recondition rods, bore and find matched bearings (oversized?)
b. Clean rod bearing seats with alcohol
c. Oil inside of bearings but not in seat, work in oil to crank
d. Assemble rods to torque spec with matched bolts
e. Measure play (plastigauge) to verify correct size bearing
f. Also do replace crank bearings (below).
7. Measure crank bearings for wear
a. If crank or rod bearings worn, replace with new bearings (oversize?)
b. Plastigauge new bearings once torqued and seated to verify correct size
c. Clean main seats with alcohol.
d. Oil inside of bearings, torque mains down and rotate crank with oil in inside of bearings.
8. Measure main seats. If round, leave. If out of round:
a. Re-bore mains. Select appropriate bearings
9. Measure crank journals. If out of round:
a. Machine journal to round
b. Replace bearings (oversized?)
10. Measure crankshaft thrust bearing play. Recondition if necessary
11. Check assembly for balance
a. If out of balance for 6,700RPM, then re-balance rotating assembly
i. Flexplate
ii. Torque Converter
iii. Crank
iv. Pistons
12. Replace front and rear main seals and covers, reinstall everything and torque

Video: Here is a decent video on inspecting the bottom end
NOTE: This video does not describe matching and conditioning rods parts. Before disassembling anything for yourself, if you're not an expert, JUST TAKE IT TO A MACHINE SHOP AND HAVE THEM DO EVERYTHING.

-----MEASURING PUSHROD LENGTH WITH A PUSHROD LENGTH CHECKER-----
NOTE: This applies to engines with non-adjustable rocker arms:
Buy the pushrod length checker here - https://ebay.us/UXqjf3
1 - have your heads and head gasket on and torqued to spec, and valves/springs, camshaft and lifters installed
2 - put the length checker on a valve lifter through the hole in the head.
3 - Rotate the crankshaft with a 24mm socket and wrench, while pushing the pushrod length checker firmly down firmly to ensure that the lifter is making contact with the camshaft lobe, until the lifter is at its lowest point (when it is contacting the base circle on the camshaft).
4 - Bolt on the rocker arm and its pedestal until it is snug. do not over torque.
5 - unscrew the length checker until it makes firm contact with the rocker arm and has no play at all in it. make sure it is seated in the rocker arm cup and not binding on something else!
6 - take the rocker arm off and take the pushrod length checker out. measure the pushrod length checker on a caliper from end to end, careful not to twist it and change its length.
7 - repeat steps 2-6 several times on both heads for both intake valves and exhaust valves. Record each value and take and average for both intake and exhaust. EXHAUST AND INTAKE CAN BE DIFFERENT, DEPENDING ON YOUR CAMSHAFT!!!
8 - add the half of the lifter "squish," or the amount that the lifter preloads to each of your measured lengths. I am not sure what half of your squish/preload length is, but it will probably be between .025" and .075". Call the manufacturer for info or look up the specs.
9 - find a pushrod that is closest in length to your intake and exhaust pushrod measurement calculation and order them. I would advise getting a pushrod of no different length within 0.010" from your measurements if you can find one. As far as pushrod diameter goes, that is up to you. I run two different ones: One is a 3/8" thickness and the other is a 11/32" thickness, because that is what sizes i could find the right lengths for. You want a good balance of strength and lightweight pushrods, depending on how aggressive your camshaft is. You can't go wrong with anything ZZP sells although expensive:
https://zzperformance.com/p.../zzp-custom-pushrods
keep in mind that stock pushrod length is 7.029" if that is closer to your measurements than a 7.000" or a 7.050" pushrod. Do NOT re-use pushrods if you are changing your rockers. If you plan on keeping your stock rockers/pushrods/lifters, make sure to keep them matched to each other and each cylinder, to keep each with its respective wear patterns, and mark which direction the pushrod went. If you change ANY part (cam/lifters/pushrods/rockers), buy all new parts. Stock pushrods are 11/32" thick for a 3800.

Thanks Austin: lots of good information here. Everybody's swap is different, so the more info we get the more options we have to choose from and the better decisions we make. The electrical diagrams you posted are especially helpful, as are your videos on youtube.
thanks again

I'm the original owner of a white ' 84 2M4 purchased Dec 10, 1983 from Pontiac. Always garaged, no rust, 4-wheel drifts are fun! 3800 SC swap to come!

How did it turn out?

Amazing post and lots of valuable information here. Thanks for documenting your swap and all the information so well!

It’s not like I am an expert but the crank becomes positive so I believe the flow will be opposite of your explanation.

Air through the PCV valve can only travel the direction shown. Intake vacuum sucks air directly into the blower through the PCV from the crank case.
