So i'm now in the process of swapping out my d15b(95 EX) to a 98 b18b motor. (In case u're wondering, i had to replace my d16z6 cuz it blew, thats why i have a d15 in there). I wanna keep my car obd1. I got a HELL OF A DEAL on the swap from a j/y. I got everything: dizzy, axles, p/s, a/c compressor, engine harness(not ecu), alternator, 5spd tranny, shift linkage, exhaust manny, and all mounts for $935!!! minus ECU.

Anyways like i was saying, i want to keep the car OBD1. I heard that you can swap out the OBD2 connector piece or something within the dizzy AND alternator to the OBD1 so that they would work. How do i go about doing so or what shall i do??

I dont want to have to buy another dizzy and alternator. Which ECU to use? P74 or P75, which is for manual tranny??

Thanks guys!

Very easy swap just plug the 98 integra harness up to your civic plugs at the firewall. I got a jdm b16 with obd2 injectors/distributor/alternator with a usdm 99 Gsr engine harness in my 92 hatch and everything works. I am using a p30 obd1 ecu, but you will need a p75 from a 94 or 95 integra or a pr4 from 92 or 93 integra. there is no need to mess with the distributor or anything else for that matter just plug and play. Seems weird right I almost didn't believe it at first. Hope this helps.
