:confused Well first off, i cant find a b20z block so im stuck with a b20b unless anyone knows where i can get a good used one. Second which parts are going to be interchangeable with my current b16a(using this head). Third will this motor drop in my 91 hatch with my b16 motor mounts. Forth is the tranny compatible. And fifth how the hell do i do it all????? damn im stupid!
