Same as D16Z6 (OBD1 Civic EX) swap. I would say just get an OBD0-OBD1 conversion harness and then you'll have to insert some wires for the VTEC selanoid. Also, use your stock CRX mounts.

 

You need to convert to OBD-1 using a conversion harness get either P08 ecu which is the correct ecu for your motor or P28 which is the z6. Id recomend using your Obd-0 injectors so you dont have to deal with the injector resistor box. Also you use all your Crx mounts but you will need to switch the mounts by the timing belt from your old motor to the new one.
