the STI is not far from 450 hp, it already makes 300 and it isn't that hard to make it go to 450 hp, and also why are u guys talking about longetivity, YOU CAN CONTROL THE BOOST IN A TURBO CAR, just get a boost controller and u can practically turn off the turbo so even if u have 2387409124921hp when the turbo kicks in, it wont work til what? THE TURBO KICKS IN, if u control the turbo and it doesn't kick in til later whats the chance u will break the engine? also who drives a 450hp+ car as a daily driver if u can't control that horsepower and pay for the gas AHAHAH
