Instead of buying a t03/t04e turbo and running it on my b18c1 w/stock internals, could I just get the bigger sc61 and run it on 7 psi or so until I build the motor with at least block sleeves, rods, and pistons? This is the turbo I want in the end but I don't want to buy 2 turbos until I build the block and port the head. Thanks a lot.
