I'm going to b20 swap my crx soon, figured out most of it but just wanna clear up the OBD side of things. I have a complete orthia as a donor car, couldn't I just swaps while loom etc over to the CRX and make it OBD2 since ill have all sensors distributor etc to match. Or is obd0 and getting obd0 distributor ecu injectors etc better?

I'm not planning on doing much to the engine other than exhaust and intake so not worried about tuneable ecu etc

 

To much work....

OBD1 B-series distributor
OBD1 B-series Alt
OBD0-OBD1 jumper harness
OBD1 P75 ecu if going non Vtec B20
OBD1 P75 intake manifold and TB
OBD1 injectors and eliminate the resistor box.

 

long as you have obd0 ls ecu and injectors aswell as the distributor

 

All depends on if your going non vtec or vtec. If you are going Vtec I have great guide.

 

I'm not going vtec. It just seems buying all those extra things is more work lol when I have an entire car already there to use

Makes sense for vtec and tuning as obd2 hasn't really been done much
