I have a 1991 civic hb 5 spd, cable clutch. It has a D15B1 in it right now. I have a b18c1 to put in it but all I have is the block. I was wondering what head I should get for it. I plan on building it for a turbo. I wasn't sure how hard it would be to go vtec or if I should. Just need some tips on best parts and the easiest way to do it.
