I have a 2004 Pontiac Grand Prix GTP. I recently blew the engine and I need a new engine. I was wondering if I could by a regular 3.8 engine out of another Grand Prix and hook up the supercharger that is already in my car to the new engine?

No, I don't believe you can. I think the regular engine has a higher compression ratio which would need to be lowered to what is required to work with the supercharger. Unless you are prepared to make that modification and possibly others you will run into trouble. The 3.8 is a good engine and they built tons of GTPs. I'd do a bit more searching and get the right engine even if you have to spend a few extra dollars to have it shipped to you. An engine swap on a FWD is a lot of work. You don't want to end up doing it twice.
