Hey guys so I have a 1998 3.8 Firebird. Has 190k miles and I wanted to replace the motor and trans however I was thinking about putting a supercharged 3.8 in from a 2002 Grand Prix. Now I know they’re fwd but I’ve seen people curve the back around. Now what I’m curious about is will the motor bolt right up? I’m assuming I will need a new pcm or get a tune. Just would like some thoughts.
