GT vs GTP

I'm sure this has been asked before, but i'm looking to fix up my 04 GT2, and possibly slapping a super/turbo charger on, and that would probably affect some of the parts i'll purchase to upgrade. My question is, is the only difference between a GT2 and a GTP the supercharger? Or are there different internal engine components?
 


Well, yes, the engines are more the same than different, yet there are differences.

But just as a friendly warning I have only seen a couple people on this forum actually pull off a top swap on a 04+ and actually have a running car a year later. I have read peoples accounts, and it doesn’t sound like fun at all to be honest. IMHO get a PCM tune, slap on a set of 20s and be happy.:th_peaceout:
