Looks good. Being a Buick motor you are going to have to change a few things out for it to work in the Fiero. If it came with the aluminuim SC tensioner setup, you will need to get a steel one from a GTP. The oil pan I believe will be an issue if you plan on running exhaust out the stock Fiero location. Nothing major, just a heads up on a few things.


You will love the swap once it is complete and on the road with all the bugs worked out. Get ready to spend some more money on MODs, cause you will get the urge.

Looks like I need one of these huh?

NO--I am in chat if you wanna talk about the swap.

Yes I do want to talk to you but I cannot connect to the chat right now for some reason--

The tensioner I believe was broken in the crash so it's missing
He sold the a/c compressor--)*&^#$%^
? alternator options/brackets
oil filter adapter--

I'm guessing everyone except darkhorizon is buying mounts/brackets from Purple Reign?
Prolly get FieroFlyer to do my harness

Not sure whether to keep my 4spd muncie centerforce clutch
or go with 5spd getrag
or find a 4t65e hd and go auto

I want great gas mileage and will never go down a 1/4 mile track.

PM sent

Looks nice, good luck on your swap.

Jeff
Good luck w/ the swap and I hope everthing goes well.
I look forward to seeing your progress

A lot of people have made their mounts, I did.

A cheap $130 welder, $10 worth of angle iron, some practice and you'll have yourself some mounts no problemo


I'd also give the harness a shot yourself, all the information you need is on here bro:

https://www.fiero.nl/forum/A...070315-2-074653.html

Go about 2/3 down and there are some charts that have all the matches for the c203 c500 etc.

Then, just go here:

http://home.att.net/~subzero350/index.htm

and compare the chart with the pdf of your wiring, some of it might be different

With those two things, I completed my first harness in about 5 hours.

Also, if you aren't going to be going to the track, the trans you have will hold up just fine. But, the mileage will be better with the getrag I believe

Mileage would be somewhat better with the auto technically, but only if you do alot of highway driving. The muncie hardly got 20mpg on the highway when we had it in there. Granted the maf curve was dumping like 4% extra fuel at the time, but it was spinning at 3100 some rpms. An econo would drop that significantly if you could piece that together easily.

If you dont want to mess with swapping out broken transmissions, I would also suggest the auto for that, the muncie in MY PERSONAL experience has had trouble in more situations than just the diff exploding from launching.

Ultimate 3800 swap thread

Only reason I didn't suggest auto is because it's a pain to change from manual to auto, and that he said he won't be romping on it

My four speed netted me 32 MPG the last time I had it on the road for a 600 mile one way trip.

Good luck with the swap. I am sure you will love it!

I agree if you have the time do the entire swap your self and just take your time and do a lot of reading up on the swap here on PFF.
The engine you have will work fine depending on how you mount the engine, unfortunately most mounts you can buy will not work with the oil filter adapter and aluminum oil pan your engine has on it. Good thing is the oil pan, oil filter adapter and alt bracket from a 3800N/A will also work on the SC engine. Dan

That oil filter adapter will definatly have to go. I have spares But I dont see any issues with the oil pan

I could imagine this is possible if you keep the speeds low. My friend drives like a moron too, so that will easily throw off a mileage calculation with that setup.

I know he REALLY liked it when he put the getrag in, it was very nice for highway driving and IIRC he got slightly better mileage when we went to the track.

i see xmas came early....all i can say is it worth it in the end.....:0

my 4 speed 3800 with 3:65 final drive got me 26MPG highway from charleston WV to blackrams house in kentucky, that was with a couple 100+ MPH spurts, its all mountains, no flats, and i didnt have working cruise.

i think at 65MPH with cruise set in a fairly flat area id get 30+ mpg.


the 4 speed will do fine, but you'll probably have to either get a custom y-pipe made to clear the shift cables, or do like me and modify your "firewall" side manifold so it dumps the exhaust down in the stock location, seal up the end on the "trunk" side and route the exhaust down there, and have true dual exhaust.

matthew

my swap eliminated the xover by using a modified mustang manifold...now some slam it for not being the best choice....but for me running with the 4 spd it works great...others say you loose top end...i say they dont know wtf they are talking about...my car hauls azz in all 4 gears....my azzometer says shift quick or hit the rev limter at 6500 ....you can use these to go duals or my set up uses a 1 inlet and a 2 outlet muffler...its a magnaflow part # 12158.... myself i am very pleased with the end results....just tossing another option your way....tim...ps i didnt have to loose any of the trunk either....

Jeff, what are you doing with your turbo setup?

Oldsdoctor has asked me to give him first dibs on the 3.2 turbo but I have been soooo busy
so I will let you know after I contact him if it will be available or not.

Can someone enlighten me, from the pics, as to what basic items I am missing?

The a/c---can I use my Fiero a/c there?

Alternator---?? options??

What pulleys are missing? where to source these ?

Thanks Jeff

You are missing the A/C compressor(wouldnt use the Fiero one), the Alt(can use either the 97/98-99up-Fiero/would use the GP Alt though) and the SC tensiner setup. All these parts can be bought from Ed Morad if you want to get them all at one time from a good source.

I agree! Ed Morad is the way to go, when needing 3800 parts. If you can think of it, he has it. You can find him on E-bay - http://stores.ebay.com/Mora...3amefsQ3amesstQQtZkm If a part, that you need, is not listed on E-bay, just give him a call. 216 798 6902

I should start undercutting him, because i get my stuff for less than half what he sells stuff for.

These 3800sc have dual egr tubes? I guess my egr is missing?

well get your soldering iron warming up!

Best thing to do is make sure ALL sensors and other stuff is pluged in then strip all that loom off there THEN see where you are at.

Large bracket is used for lifting the eng. ---get rid of it

No egr is on there, are you going to need the emissions for testing? if not no problem just have the pcm delete that.

Last = no need but save all wires!!!!

uhm... a 3800sc version of a Blue Dingy Thingy?...
do I win anything?

The injectors are missing too--going to have to compile a Needed List

a set of injectors
I also need a gtp oil filter adapter
and a supercharger tensioner bracket and pulley
and an ignition module-I have the coils
and a 97-99 ecm? I have the 2001 but I don't think it's useable?

The big bracket is a factory installed bracket to pull
the engine.
There will/should be another on on the other side of the engine.

Those can be removed after the install..

Good Luck...

I'm going to do the same swap next year..

Mr G's 88GT
aka Tim

feel free to chime in on the Needed List

I am hunting down some items over on clubGTP

Cool! Another step-by-step install!

The thing you refer to as "#5 is part of the original GTP fuse box or whatever the motor came out of. The fuse box has stuff like a fuel pump fuse and other things.

The big plate is to help hold the beauty cover thing in place, just remove it to get it out of your way. Your harness still has the MAP sensor plug so you can always just go get an engine harness that has not been cut up from a 3800 N/A engine to work with if needed. Four of the extra wires by the oil filter are for the second O2 sensor which you do not need and there should be a blue wire there for the knock sensor.
If you are not using the EGR then just cap off where the hoses come from the exhaust manifold and the intake, if wanting to use the EGR the one from the N/A engine is the same. Dan

Looks like you have more than enough of your harness left, and the 2001 PCM is fine for anything, the 99-02 pcms are all the same basically. You are going to end up cutting back almost all of the harness parts you have pictured, all you really want to keep together is any of the PCM to engine connections, as you dont need to disturb those. One bonus to keeping them together is the fact that you can be assured that you didnt mix up any of the wires when you put the swap harness together.
