My 90 civic had a rod knock to it so i am raplaceing the motor , i put an ad out saying a need a motor and found one but its a twin can d16 zc motor , I am not familiar with this motor . Can i use the harness from the soch ? as well as intake and exhaust manifold , computer , distributor ? is it all campatable with the twin cam zc ?

 

you will need this adapter http://rywire.com/store/dohc-distrib...33c363a4f11e5c

and everything else you can reuse and use your stock engine harness

and you will need to use the zc distributor

 

Which version of the ZC? Theres at least 3 different ones (early model for '86 - '89 integras and '84 - '87 civics OBD0, second gen OBD0 '88 - '91 model found in JDM civics, and the 3rd gen OBD1 version found in JDM '92 - '95 EG5 civics).

Make sure what your getting is one of the last 2, the first one physically wont bolt up to an '88 - '91 chassis. I seem to recall that ZCs use an oddball intake manifold. You will need to grind the inside of your your exhaust manifold too btw, the ports are shifted over slightly to one side, but the bolt pattern is the same.

Im not sure which version it is , the guy told me that it will bolt right in , and that all was compatable with what i have now but it seemed to good to be true . I think but am not sure i think its the version from 88-91 jdm civics because . I have an ebay header from the sohc i was hoping would fit , and it does not come with a distributor , do you know which one i could use in place of it ? thanks for the help .

 

D16A1 distributor from an '88 - '89 integra should work.
