i need help on putting together a cx block with a jdm zc head my main concern is the timing belt. which one to use cuz i think the stock zc will be to long and the stock single cam will be to short any help much appreciated

 

if CX bottom = d15b7 bottom = it needs D16Z6 Timing Belt Kit (106 teeth)=tensioner pulley as well

if CX bottom = VX = it needs VX Timing Belt Kit ( 103 teeth) = tensioner pulley as well

 

its the dohc head bye the way

 

d15b8 botom and a dohc head

 

the short answer is that the D-series twin cam head, the ZC, does NOT go onto d15 and d16 SOHC designed blocks. The long answer is that it IS doable. Search h-t. Someone actually did it, and with a turbo. The engine looked bad, and he blew I think 3 or more head gaskets, and it DID require some custom work. It was not close to OEM reliable, so if you have a shop with a master mechanic and a good engine builder, you CAN do it. If not, consider it like a B-to-D head swap, they just dont fit.

Look into the JDM D15B head with the 3 stage VTEC setup, it'll be better and will bolt on, rather than the BIG hassle of all that **** just to end up with a engine that is still not as good as a stock B18.

 

cool thanx for the info
