I have a 2003 grand prix GT. Last weekend i replaced the intake gasket, upper plenum and coolant elbows. Everything went well but the problem was the guy who owned it before me put **a lot** of sealant in. WAY too much. Long story short after doing this and attempting to flush the system out the sealant managed to block something off somewhere in the system and i overheated my car. The coolant was legit boiling. Anyways engine is knocking and is fu******d. This means IM basically fu******d. But i work at a dealership so all my buddies are going to help me put an engine in. Now here come the questions. Do i get another regular 3.8? Or do i get a supercharged 3.8? But will a supercharged one fit in? or will it just eventually kill my tranny? I think i will be buying a full grand prix (GT)(P) and swapping the engine and this way i have a car for other parts. Just need to get the minor details figured out and i gotta go for it. I can still drive the car but there are no guarentees to how long she will run for. Thanks guys! Any advice is wanted!
