Which engine?

a sideways drivetrain behind you...

I vote the inline four. it is far enough away.


I drove one of those just once..can't remeber mr2 from a fiero..but do remember engine was crazy large even as oem.

more air, and room..very light go kart. boost would be fun if it fits as well.

they have some hotrod stuff for the 2.8, if the ecotech fits they run good, even the one in my wifes o4 cavalier runs good

Do you need the car for transportation? Just keep in mind that an engine swap on a small car can take quite a bit longer than you planned on.

I have an 86 Fiero Gt. Im 16 so im not loaded with money, but i have a question on an engine to run. I have the original 2.8 v6 but as any guy does, i want a little more power. I've thought about the supercharged 3800 but i know the fitment is a little more tighter than the original v6 (which is really tight). But a idea that came to mind was one of the new ecotec motors, like the 2.2 out of the hhr's and cobalts. I can supercharge them and there are a ton of aftermarket add-ons, plus it will still get better gas mileage than the 19ish im getting with the 2.8. Whats you opinion? Keep it Stock or change it.
