cant use gt28 cos it already max out at below 500hp..upper class is gt30r then next is gt3540r..so.. depend on ur engine setup..gofor gt3540r for maximum capability by using.63 turbine Ar..i said this because of..to maximized hp on gt30r u need larger turbine ar..which mean u need to sacrifice ur boost threshold ..so i vote for gt3540r:proud: for 500WHP..are the GT28 can handle for 500 whp evo 4 ?
or what the better turbo ?
