Ok im confused. I have 2 cylinder heads, both are labeled PR-3. One appears to be obd0 tho, all the connectors are clear plastic type material, the vtec solenoid looks a lil bigger than on my other PR-3. On my known-OBD1 PR-3 head all the connectors are green opaque plastic, and the dizzy has 2 plugs coming off it, the other dizzy only has one.

Are there 2 different PR3 heads, one OBD0 and one OBD1? Can I use my OBD sensors on the PR-3 OBD0 head? Will there be any issues doing this? Like if i use my obd1 dizzy and vtec sol on the obd0 head, will all the other sensor match up with my obd1 harness?

Im so confused. Please help

 

There are 2 pr3 heads. An obd-0 one off a pre-92, 160hp jdm integra b16a, and an obd1 version off a 170hp 92-93 jdm xsi integra b16a.

Sorry I can not say anything as to the compatibility of the parts.

 

aha, ok then i have both lol. anyone know about compatibility? I know the that the ob0 dizzy and vtec sol need to be changed but what about the other sensors and the head itself?
