I blew my engine in my 96 civic. It was a stock d16y7. My friend has a d15b8 with d15b7 complete swap that I am going to pick up this week and was wondering what else I would need to do the swap. The engine is obd1. It comes complete with tranny,longblock,axels,and wiring harness. Only thing I should need is a ecu right? if so what ecu should I use

 

P06

 

Is it a D15B8 or a D15B7, because you listed both? Regardless, both of those engines are OBD1, not OBD2. You'll want to use your stock harness, because it's a 1-piece harness, compared to the harness from the '92-'95 Civics, which have a 2-piece harness. You can use your stock transmissions and axles if you wanted to as well. As for the ECU, you're going to need to get an OBD2A to OBD1 conversion harness. If you're getting a D15B8, you'll need to get the P05 ECU. If you're getting a D15B7, you'll need to get a P06. They have 2 different ECUs, because the D15B8 is an 8-valve engine, compared to the usual 16-valves.

 

sorry its a d15b8 block with a b7 head. so if i take the motor out of my car can I just drop this one in? is there any plugs I have to change in order for it to work. I have every plug and piece from the d15 and the d16

 

You could use most of the parts from your car; like the distributor, intake manifold, and injectors. If you have both alternators, you could swap the voltage regulator (the part with the plug) from your stock one into the one from the D15B8/7.

You also COULD use your stock ECU, but the fuel and ignition timing maps will be off; which will probably effect emissions testing. But using an OBD1 ECU will effect emissions testing even more. Something you might need to think about.

 

just to let you know, if you though your y7 is slow this motor you actually can out run it. lol
