im swapping a b18a1 into a 91 CRX si...i was just wondering how hard it is going to be to convert obd0 to obd1...if anyone done this all tips would help...thanks

 

It would be easier (and cheaper) to change the injectors and distributor to non-obd (90-91 Integra) and use your stock engine harness. I think the only mods to your stock harness would be to lengthen a few wires.

I'm pretty sure you can just use your stock si injectors in the ls manifold. If you don't want to, just bypass the injector resistor box and keep the 92 injectors and you'll be fine.

 

Good idea to keep the stock Si injectors, I don't think the 92 obd1 ls injectors will plug in or work with the Si harness.

I could explain it all, but I'm lazy, these guys are talking about swappign a vtec engine into an OBD0 crx. But it is very similar to what you are doing.

Yeah... I'm assuming you have the obd1 plugs/harness along with the engine
