well a dohc head off of a d16 zc motor fit on the d15a3 motor

 

no

 

o yeah and the headers and tranny

 

what about the tranny and headers and even the wiring in a 91 crx si

 

Wires are merely little pieces of metal. We use metal because it conducts electricity well, SO wires are pretty much universal. If you want to be more specific as to what in hell you are trying to rewire maybe we could be of more help. The header might fit but it will do nothing. Correct me if im wrong but the ZC is an inline four it should only have one header. The transmission should fit but you should consider finding a job and saving up for an actual motor to bolt up to it.

 

nothing on the 88-91 is compatible with the D15A3

 

i think i know the answer to that i have a 86 in the shop here at work i noticed and it looks like a totaly diffrent animal

 

thank u jlicrx and aviglakis go screw your self any time u want to race i have a 79 camaro that has HEADERS that will bust any 4 banger u got im tring to help out a friend

 

lol, was that your feeble attempt at sounding hard?
wrong forum buddy.

 

 

I bet you can't beat my golden airplane. Its way more fasterer than jooo will evar now!

 

The tranny will bolt up.
Wiring is universal.
Header will not work.
Intake MIGHT work.

Swapping a DOHC ZC into a DX or CX is more work than you think though. You have given us no good information, so I am going into assumptions. You will have to do the MPFI swap for sure, and good luck finding solid info on which axels to use with the ZC tranny. OEM ones are big cash.

If you REALLY want a DOHC head on a SOHC block...
The first link on this page works.

It really wasn't hard to find the info.

 

the 88 and up transmission will not bolt to the D15A3 - completely different bolt pattern
