Ive heard that you don't have to change the wiring harness in a HF to install a ZC. Is this true? I know that there a few changes you have to make because the distributor wires aren't the same. Also, is the intake manifold/tb on the ZC interchangeable with the si? If it is, will the Skunk2 Intake manifold made for the CRX si work on the ZC? What other aftermarket parts are readily available for the ZC motor?
