forget about that....just get a b16 or b18 and leave it at that. there aren't too many successful swaps done like this. some WORK, but not like just getting a stock engine and putting it in. the reason people do that is cause it develops similar torque of the larger block, like the b20, and similar top-end like the b16 or b18. i personally wouldn't mess around with it....i hear making sure that the extra oil gets around is a pain. just what i hear.
