hey i was wonderin how hard it would be to put a gsr head onto a b20? is it gunna bolt up? if not wut do i gotta do?

 

check out www.b20vtec.com its the same process as ls/vtec.. you need different dowel pins to line up the head.. you also need to build the bottom end if you plan on revving up above the factory b20 engine redline.. or you might blow something up.

this has been covered pretty thoroughly.. search around. the answers are here
