i got an 88 crx si D16a6 and im going to pull it out and build it i got an zc to put in it but will the stock si mounts work on the zc or do i need some other mounts also will the zc motor harness plug in to car harness and will it run off the pm6 if not i got the zc ecu?

 

single or dual cam ?

yes it will run off the pm6 and harness fine.

 

dual cam

 

It will drop in with D16A6 mounts...and the harnass will fit.
It's basically the same block from the outside....

 

there are 2 wires you will need to change out, but its a very easy swap. my girlfriend and i did it in about 6 hours.
