i HAVE A 90 ACURA INTEGRA AND HAD ORDERERD A DISTRIBUTOR. WELL COME TO FIND OUT THAT IT WAS A OBD-1 DIST. SO THEN I WAS WONDERING WHAT ARE THE EXACT PARTS THAT I NEED TO DO THE CONVERSION AND IS IT A DIFFICULT CONVERSION??? CAN ANYONE HELP???

Iv got a feeling that Dropzone will be here to answer your question.

Actually, I've never really been totally sure on the upgrade parts for swapping to OBD-1... I'm pretty sure you just need the ECU and a jumper harness though. You can get full instructions w/ a jumper harness from HaSport and RyWire, plus several other companies.

I do know that if you're only going to do the swap to negate having to send the dizzy back and get the right one, DON'T. You should never do unplanned work just to negate a few dollars out of pocket, you'll always end up spending A LOT more than you thought or planned, and there is no immediate return for swapping to OBD-1 unless you plan on tuning for boost or something, or using Vtec

Distributor, ECU and a 4-wire O2 Sensor are the 3 things off the top of my head.

But like Dropzone said, don't do it just to negate sending the distributor back to get the correct one. If you have other reasons, go ahead. But you are looking at spending money on a new ecu, o2 sensor and a conversion harness.
