I am building my h23vtec at the moment and am almost finished with it. I just have one question. Can i use my h23 distributor on my h22 head? The head was from an obd2 h22a4. and i have a p13 obd1 ecu for it. Also, will the obd2 injectors work? i was wondering because i read something about one being low impedence and one being high impedence? just wondering if it was true.
