i recently purchased a 87 crx si, for 100$. It has over a quater million miles and it time for a swap. I read in the forums it can be done and with what engines. I have 1500 or so to spend. Maybe a little more. I was wondering if a b16a1 would go in easily? What, if any, modifications would i have to do to make this swap work? Me and my friend were gonna do it, since he has before, successfully. Any other parts i need to get for this swap? thank you in advance.
