OK..i just bought a b16a bare bottom end off a friend. I plan on getting all the internals and all wiring myself. I have '97 Civic DX...OBD2. This b16a is a slightly older motor..i think, therefore is not obd2. I don't even know what car or what year car this came from. I had planned on getting a b16a2 cuz i know those are obd2. But those plans all went to hell and i bought this b16a instead. Does it matter though? Because all i have is the bottom end...can i still use the obd2 wiring harness with this older b16a block? What would i need to buy for this motor to properly install and not have any wiring problems? What harness would i use? Do i need to do some type of OBD conversion? I have no idea. Plz help. All suggestions are appreciated. Thank you very much.
