you could turbo it instead. i don't have any real knowledge on it but you might want to look into it. one thing that nobody's said and idk if you realize is that the gt and the gtp's have different gears which is another reason you would want a different transmission. i've heard doing a whole L67/trans swap is easier and could be cheaper, just good luck finding one. but yeah, as it sits now, the supercharger is about useless. props on moving onto american cars. just please mod it right lol.
