Here is one. Its a 1984 T-top IRM/Hi-Tech turbo 2.5L/4.10 4 speed. Its suppose to be 1 of 10 and the only one with t-tops. Used to be mine but I sold it to a good guy, Jim, in Williamsburg Va. I work on it from time to time. These are the original pics from the day I bought it back in 98. Its slowly being restored. Many have seen it while it was at The Fiero Factory.
Next time I see Jim I'll try to get some recent pics.
An interesting swap that I just recently heard about is the 2.0L Turbo engine from the 1988-1990 Sunbird. With modified Turbo and work done to the engine, it can produce over 245Ft/Lbs of torque all throughout the powerband...I want to get one of those!
I do beleive you may be sort of wrong there. However it doesnt matter since the sunbird motors were crap anyhow. There top ends were strong enough for the the boost, however if you ever dealt with one youd realize the bottom end is the fault with the sunbird motors.. Plus for a turbo 4cyl, they had a bad power band. The head gasket issue you may be speaking off occurs to the NA 2.0l Gm 4cly and the of course the infamous Quad four. When GM turboed the NA sunbird motor they rengineered the head and gasket spacifically for that application "suprising for GM". I do believe that the "GM" (vauxhal) turbo 2L 4cyl did work OK for its application other than main bearing exploding and oil burning, and all the other issues it had other than head gaskets..
My dad used to have one. I dont really know anything about it except that it was white. He bought it as a parts car because it was blown. He took a couple of parts out of it that he wanted and sold it again. He took the whole engine out of it and kept what he wanted and threw what he didnt want, including throwing the turbo. He said it wasnt a true fiero turbo ?! He realized soon after that it was a good usable turbo. I still bug him about that...

I'm pretty sure I have (one of?) the only 88 GT Turbo 4cyl. It isn't finished yet, but the final component -- valve springs-- should arrive within the hour, so I can get to work finishing this thing up!! I'm hoping to be the first 4cyl Fiero to make it into the 12's! The beauty is, the loss of over 60lbs on the back end will make autocrossing much more fun also. I ended up going with a stand alone ECU (Electromotive TEC3) because the duration on my cams is 232* at .050 if I remember correctly, and I plan to be able to run around 22psi at the track out of my T3/TO4E 60 trim. Also, I'm going with 850cc injectors, so the TEC3 seemed like the best way to keep the car civil for everyday driving. --Bryson

Yes how cool it is, thanks for the props $Rich$. However i dont know if I exactly count on this topic, unless you consider out of make swaps... with turbos! As for my swap... still trying to hurdle the money issue! Anyone wanna donate like $1,300 and ill be done hehe! Im just waiting for someone to t-bone my Laser RS... That will give me a reason to put a 360hp 4 banger into the Fiero asap! I'm pushin about $4g's under the hood of the Laser now. I need to stop putting money into it, the damn car has enough gizmo's, gauges, and lights as it is!

The top ends were also junk. My turbo sunbird blew 2 head gaskets and cracked a head before I parked it (waiting a v8 muhaha). And I don't believe the head gaskets are different, I never came across 2 head gasket numbers when I was hunting them.

The Quad4 head gasket problems were caused because GM didn't take into account the different expansion rates of the iron block and the aluminum head (I believe). This problem can be solved with a quality aftermarket head gasket. --Bryson MAN I NEED MY CAR FINISHED

there is probably one for the ohv, and the ohc(gm made 2 different 2l engines(chevy and pontiac) in the late 80's j-bodies)

Oslo, What turbo are you using? What Size is used on the MR2. I think it would be sweet if someone used an MR2 turbo on a Fiero Yes I have a 2.5 that I am thinking of throwing a turbo on. And a 2.8 as well HECK, Guess I will just haveto get two turbo's!
