Sure it's possible you need a new wiring harness and computer probably have to change gas lines and need some of the exhaust from the 3.8 along with new coolant hoses., the complete aiir intake system , different motor mounts and alternator. The Ac system will probably be different. Would imagine that I'm forgetting a few things but thinking your changing engines for more power . Cheap and easier way would be with a shot of nitrous oxide.

Yes very possible and actually quite common.. You only need a few pieces out of the 3800 car other than the engine.. The wire harness, get it tuned, and the MAP sensor to read boost..

Theres plenty of guides around here im sure also..


This guy is probably one of the better known for doing this swap..
