Now, I have been told, that the DOHC ZC head will fit right up to a sohc block, header, intake, etc. Also was told that a dohc zc motor is a sohc size block (like a z6) with the dohc head on it. is this true?

 

a dohc zc head will NOT bolt up to a sohc block,intake manifold the block for the zc is the same size as other d16 blocks but the bolt patteren and cooling passages do not match any sohc d16/15 blocks any other acceserys will bolt up thow i.e. exhaust manifolds most sensors altenators you get the point

 

it will work with some modifications.
do a search and you will find one guy that has done it.
he actually used a d15 block.

 

not worth it zc sucks. u might as well go b16 or go d15/16 vtec.

 

zc's rock

 

Hybrid shows this for the dohc ZC:
137 bhp @ 6800
108 lb-ft @ 5700
Redline: 7200 rpm

 

thanx, i was just curious. I have a jdm D15B vtec turbo setup in my civic, and if that worked i was going to buy a zc head... jus thought i'd ask first! also on the subject, I plan now on swapping with a LS motor, but i wanna do LS/vtec. what head will give me the lowest compression ratio and best power output with my turbo on it?

 

best power output would be gsr, higher compression. B16 will give you the lower compression ratio due to the larger combustion chamber.
