ok ihave a 90 crx si that i plan to go turbo. Do i have to change over to obd1? how hard is this? also for the stock motor in my car what size turbo should i be looking for i had a integra and was going to use a hx35 but im guessing that might be to big for this motor. thanks jamescb77

switching obd has to do with the tuning program.

turbo edit uses obd0
most others use obd1.
