Largest BB Turbo recomended

a friend of mine has the ptc bolt together it a trick peice.im running a 64billet with an strim turbine with bb.i can tell you the 9.5 is worth the paper,the car does not have a stock motor and has a healthy amount of comp to it, cant see putting that wheel on a stock motor.i also say i have been in a 70mm bb stock motored gn that couldnt pull on a 49 turbo/stock motor combo upstairs.on these cars we dont get alot of rpm so things have to happen early.to big on the comp or turbine wheel will kill the torque.
