You helped me so much on my '91si. Can you help a little here please. I have searched all over 4th gen, found nothing. I have a very nice '93si h23 5sp. I want to put in a JDM h22 R w/ lsd. my questions probably are: Will it work with my computer or will I have to use obd2 and rewire some(how much) or should I just get 92-96 h22. Really want to go Type R. But is it a hassle? Wihich on line supplier is best. Thank you so much.
