The Challenge: The biggest challenge to putting the 3800 Supercharged engine in the Fiero is the motor mounts. The original Fiero's had a dog bone type engine mount for the upper mounts but that won't work with this larger engine. If we leave the bone off it will make the engine wobble back and forth jerking the passengers whenever I gave any power to the throttle. I've read a few posts online that say you can weld a few working $20 Ford motor mounts onto the frame of the Fiero and make the engine stable. There are a few other challenges like making the exhaust manifold seal and fit into that small space. Either way I have my work cut out for me, literally lol. Essentially when it's done it will run a 3800 Series II supercharged engine and transmission. The picture when it's all completed will look something like this:
Engine Output: 240HP & 270Ft Lb Torque

Why a Pontiac Fiero?
My friends ask me this question all the time, my only reply I have for them is that I've got something to prove. "Some things get meaner as they get older!" >:3 When completed this will look exactly like a stock Fiero SE, they won't realize the monster under the hood until it's too late. The only modification that would be better than this would be an extreme modification done by professional mechanics who are willing to make cuts to the frame to fit an 8 cylinder engine like the 4.6 Cadillac Northstar, or the LS-4 Engine.
The Finished Project should look like exactly like this:
