I have a 90 Honda CRX DX. Right now it has the DPI D15 in it. I want to install a ZC motor D16 like that are in the CRX Si's. Do I just need the ECU for the motor or what? Is the wiring harness different? Please help me! Reply to this thread or PM. From what I have gathered so far. I need a PM6 or PM7 ECU, OBD0 D16 wire harness, 88-91 D16 ZC motor and trans (mine is done). What else? Any help is greatly apperciated!
