Reminds me of me right now. Im in the same situation as you, ill like to talk to you more so you can help me out on some stuff because im doing the same thing as you but yeah
90-91 is OBD0 and 92 is OBD1.
Can you say what you mean again bcus i do understand but than i dont

 

Your O2 sensors are different per the ECU, which is why you are having the issues. You need an OBD0 to OBD1 harness. Check out Rywire.com dude has an awesome product for a decent price. You also need the OBD1 ECU from the 92-93 Integra. Or just a PR4 will work.

i have a 90 integra obd0 with obd0 ecu but i have done my swap to obd1 motor the 92
B18a1 after a month the check engin light came on and now my car wont stay on and my obd0 ecu is trowing me code #4 ...im thinking about getting the p30

 

if it was fine for a month you may be having other issues. There is more to it then what you have done, and just buying the OBD1 harness isn't going to fix your problem. You need a converiosn harness, and a few other pieces to go with it. Join G2IC and ask around on there. It is all G2 Integras.

 

ok thanks email me if u got more info ... guerrac_JDM@hotmail.com

 

Just hbit up www.g2ic.com Plenty of people here have done the swap so you will have all the info you need in one thread.
