i have a friend with a 89 crx si, and he wants to turbo it. He would rather turbo a dohc zc motor, and he needs to know if the manifolds are the same. Should he buy the turbo kit first, or the motor first?

 

yes, the manifolds are the same with the exception of you have to grind the manifold on the #4 cylinder a little. takes about 5 minutes

 

i'm the friend, and im buying the crx shortly...

so if i bought a turbo kit for a 88-91 crx, put it on, then bought the dohc zc motor, all i'd have to do is pretty much port match the manifold...correct?

thanks for the info by the way. i knew that the 92-95 dseries headers worked with porting, just seeing if the older motor was different

 

no need to portmatch, the ports on the single vs. the zc are the same

 

thanks for the help, but i think that i've decided to do the whole supra piston, b16 rod combo
