I got a 90 integra shell and i got a obd1 94 ls motor. My question is will I have any problems smogging with the obd1 motor in the car?

 

youll need to get it bar approved. but shouldnt be too much of a problem. idk how big of an issue it is to run your obd-0 ecu though. they could fail it for being an obd-0 ecu and not obd-1. that might be your only problem.
