I have a 1988 R31 with red top RB20DET. Question I'm wondering is are the coil pack harnesses the same between the silver top R32 RB20DET and the red top R31 RB20DET?

Do they also share the same igniters?

Several of the plastic clips on my harness broke on my motor.

Well I just broke down and ordered a new harness from Nissan for my motor. Cost me $350! :facepalm:

Would still be curious to know for future reference if the R32 and R31 harnesses are similar which I assume they are. Suppose I'll post a picture of my new one once it arrives.

I had a R31 Rb20det parts motor and the coils and injector harness were different. Mine matches with the S1 RB25 for the coil harness plugs.

I had a S1 RB25 on hand and the harness didn't match up. Igniter plug side was too big I think but didn't match up either way. Hopefully this new one I ordered gets here soon, itching to drive my car.

Fubar my bad I ment the RB25 coils matched up to my harness. You could eliminate the ignitor all together and run LS2 truck coils.

Well thanks at any rate. I have a new harness on the way so hoping that will fix my issue
