To install a 3800 supercharged engine in a Pontiac Fiero, you'll need to start by preparing the Fiero's engine bay and ensuring the engine mounts are compatible. You'll typically use an adapter plate to fit the engine, along with custom mounts. It's important to modify the wiring harness and install a compatible transmission, usually from a 4T65E or similar, to handle the power. Finally, you'll need to address cooling, exhaust, and fuel system upgrades to support the supercharged engine's performance.
biggest engine to fit is a 1.8 k series engine,no body modifications needed.
No, Fiero seats are pretty special to fit in where they are. I recomend you repair your old with parts from the fiero store.
