thanks a lot
ok, well my current budget is enough to cover both the SZ and the RZ. the only thing i'm thinking, is that insurance on the RZ is gonna be pretty steep. but if what you say about it being more costly to do the mods, and the fact that i can achieve 500hp without changing the turbos....then maybe the RZ is the way to go.
one question though, the stock turbos can handle the 500hp right?
