OBD is not of ANY concern when swapping any S13 SR20DET into an S13 chassis. There is NO distributor on the SR.

It probably would have been smarter just to start a new thread, usually whenever I have never written in a thread before and it has 30+ posts already I skip it. Start a new one to get more attention.
