Unfortunately the 90 b18a motor I bought from the yard is fucked, almost 95% leakdown at tdc, so I'm taking it back. If I end up with a 92-93 ls motor instead I'd like to know what I'll need to do in order to run as obd 0. I have searched, so plz don't flame, links are appreciated. I have a pr4 (obd 0) ecu, dizzy, and injectors which will be used on the 92-93 motor if I end up buying that year motor. Anything else I need, or that I should be aware of, obviously will be doing the dpfi to mpfi conversion, but I'm concerned about any extra **** I'll have to do if I end up with a obd 1 motor. Will the obd 1 engine harness work will the application? Thanks, any input or suggestions (links) are appreciated

Thats exactly what you need..Dont use the obd1 integra harness at all..Use your stock harness converted to mpfi and your done..Also you can use the obd1 injectors ,,just don't run a resistor box since they're saturated..The only thing Im not sure on is the 02 sensor..I think you have to get a 88-91 style o2 sensor if you run pre obd..Because the 92-95 sensor is 4 wire heated..

 

Hes right, For sure dont use the integ harness, just use it for parts for the mpfi swap.

 

Thanks guys
