I have a 1999 Civic EX (D16Y8 w/ Vtec) and i'm swapping in what i was told is a 1997 Integra GSR b18c1 engine. I'm just a little bit confused when it comes to the wiring aspect of the swap. I have a P72 GSR ECU, which i'm pretty sure is OBD1 because it has 3 prongs. I want to get my car tuned after i do the swap also, so basically i need some guidance.

Do I need a GSR distributor or will my stock distributor work?
Which engine harness should i use, or should i get a conversion harness (obd2 to obd1)?


any other tips or input is appreciated too.

 

You need an OBD2 B-series Vtec distributor (GS-R/ITR/CTR/B16)

Keep the EX harness, you may need to lengthen some connectors to reach certain sensors. If you have an OBD1 ECU you will need to get a conversion harness.
