what all do i need to put an obd0 b16 in my obd0 crx hf?can i just wire up vtec with my pr3 ecu,or do i need a whole engine wiring harness?

 

you need axles, mounts, rear bracket from a da, hasport linkage and a couple other things I believe. you'll need to run 2 wires for vtec, 1 for the 2nd o2 sensor (if the motor is obd0) and 1 for the knock sensor.....check out www.norcalcrx.org/droppedcrxsi/ there's a lot of useful info. GL with your swap.
