I recently found an OBD2 motor and tranny to drop into my integra. I found something a month or two ago about all you need to do in terms of wiring changes but I lost it.

I used to be a Honda technician and I've done swaps like this before but I had forked out the money to buy a separate harness to make it easier, it would be nice if I could avoid that this time around. Can someone give me a rundown on all that needs to be done with the distributor, alternator, etc. in order to this swap to be in full working condition?

I plan to use the OBD1 ECU.

Thanks.

 

If anything is different, just swap sensors and use the same harness. When I put a b18a1 block into my 96 Integra, I just swapped what didn't match up from the old block to the new block. It has been a couple years, so I don't remember exactly what I had swap.

 

If you're using the obd1 ecu, I'll assume you're also using the wiring harness.

All you need are odb1 injectors, distributor, and alternator really.
If you Have the odb1 motor there still, you'll be able to figure things out pretty easy though.

 

I do have the those parts from the OBD1. I'll swap them out and go from there. Thanks.
