the 88-89 Integra distributor is the same as the DOHC ZC distributor which uses a separate cylinder sensor on the end of the exhaust camshaft - it, therefore, does not have the cylinder sensor inside the distributor which is needed for MPFI - it will not work on SOHC and won't even come close to bolting onto the head - it is also clocked differentOh, and thanks for all the help and advice. I'm conflicted about the distributor because I've heard both that I can us the Si one, and that I need to buy the 88-89 Integra one. I'll stick with the Si for now and hope it works.
this is the OBD0 JDM DOHC ZC/USDM 88-89 Integra D16A1 distributor oriented the way it goes on the engine
