    You need to take the injector harnesses off of both motors, and use the one from your CRX on the new motor. Then, you will need a VTEC sub-harness from hasport to wire in the vtec, or an MSD RPM switch. If you choose to go with the VTEC Subharness, you will need a PR3 or PW0 ECU to control the vtec, or purchase an OBD0 to OBD1 adapter harness, and use the 92 Si's P28 ecu. You will need to change the drivers side mount I believe, and keep your CRX Si tranny...... Everything else is good.
