I was lucky to meet Mike Gonzalez and he essentially did everything for my swap. He gave me a list of things I needed to put the 3800SC into my '84 Notchie. I bought a good engine and a defective transmission(don't trust someone who says, "It ran when I parked it")already mounted on a Fiero cradle for $800. The Notchie was in a field in southern Colorado and I bought it for $250. Mike gave me this list of things to do and to buy:
------3800 swap parts list------
Wiring Harnesses (both Fiero and Motor)
Reprogrammed PCM--$100 Darth Fiero
Proper Oil filter adapter or filter relocation kit--mine didn't need it
Fuel pump EP376--$140 from Pep Boys
Fiero Oil pressure sender--$13 from NAPA
Air intake coupler and tube/filter ??--$50 for tube and $40 for K&N filter
Muffler/Exhaust/Tailpipes--$220 from Summit. Mike fabricated the exhaust system
Spark plugs/wires--I got iridium plugs and stock, el cheapo wires from NAPA--cost of about $70
Belts--Gates belts(American made) cost $93
Ribbed tensioner pulley--$35
A/C delete pulley, or Fiero to 3800 A/C hoses if retaining A/C $35
In Line coolant fill point, or parts to “T” off heater lines
Coolant hoses--$35 at NAPA
4’ each 5/16 and 3/8 fuel injection hose--EXPENSIVE!!!! but don't remember the cost
Fuel injection clamps--$20 pieces of Chinese made junk
8’ heater hose--about $10
Speedo buffer circuit parts (4T65E-HD only)--free. I had parts on hand
Modify throttle bracket on V6 Fiero, L4 works as is--wasn't needed
Modify/reroute vacuum lines, remove BBV lock closed
Modify heater hose connections--Mike did this
Trans cooler lines/cooler building and mounting on manual to auto swap
Build speedo buffer for auto
While car was at Mikes, I put new brake pads, rear calipers, shocks and a lot of other needed things because the car had been sitting in a field for 11 years. Mike did a ton of work above and beyond the conversion but he is a great guy and said he was bored and likes Fieros. He made the harness before the conversion so you can plan on another $250-$500 for a harness.
I like the car a lot. I never had a Fiero before this one and other than the slipping tranny and messed up TCC, I like it a lot. I don't get the high mileage others get but it is respectable; it is in the range of 25-27mpg. The car really accelerates well. EDIT: Maybe that explains my gas mileage problem.
I wanted a V8 but now that I have the 3800, I am convinced that this was the best decision.
Hope this helps.
