    as long as you keep the resistor box then the obd0 injectors will work how they are supposed to

    What ECU are you using? If you are using the OBD1 P75 then I recomend ditching the resistor box and using the B18B1 injectors.

    whether you use obd0 injectors with the box or obd1 injectors without, the car will run exactly the same. doesn't matter whether the engine was obd0, 1, or 2.

    you're looking for either an obd1 pr4 or p75. the pr4 is available in obd0 form and the p75 is available in obd2 form as well, so be sure whichever one you get that it's obd1. depending on what kind of deal you find (be it eBay, craigslist, etc) it could run anywhere from $40 to $200.
