As far as the ECU goes, you will need an OBD-1 P72 ECU (your car is OBD-1). You CAN use a chipped P28, but I would recommend going that route only if you plan on getting the car on a dyno and tuning some. If you use the P72 you will need to wire for a knock sensor and the IAB's. A chipped P28 can be programmed to disable both of those devices, but if you are using the factory GSR intake manifold, you will want the IAB's wired up and a P72 ECU. Good luck with your swap!

edit: You might want to add the other three wires for 4-wire o2 sensor as well. Use your stock wiring harness, or find a harness from a 94-95 Del Sol VTEC (B16A3) with knock and 4-wire o2 already in place. Then you just need the IAB's wired up.

thank you so much!!!!

so obd1 p7 i should get right..

i plan on doing a few mods later on to it like cam gears that shouldn't matter tho a p72 will still be my best bet right? and can i chip the p72 for a higher rev limit?

absolutely. P72 is the route I would go. You can even have them chipped later on so they can be tuned on a dyno, increase rev limit, tune air/fuel ratios, etc. You will always have the IAB control in the P72 as well as a Knock sensor, so you'll be good to go. Your stock intake manifold will perform best with IAB control.

edit: A USDM P72 is easier to chip than a JDM P72, but I can do both. For simplicity, just find a 94-95 Integra GSR ECU (USDM P72)...call it a day!

IAB= Intake (Manifold) Air Butterflies
