Help on my F20B Manifold.

[Alex13mod]

Well you all know that F20B are OBD2. My CB7 has a OBD1 wiring. The motor was converted OBD2 to OBD1. So the sensors dont match up the OBD1 ones. Do I need to replace it with a OBD1 Manifold or can the manifold be tweaked? Or a tutorial on this?

[b-bomb]

You could get the obd1 manifold I believe but I'm pretty sure you can also just get an obd2 wire harness and change that all out. It's not the easiest of jobs though. Use the search option on here I know there are plenty of threads on obd1/obd2 swaps.

Do you know what Manifold that is OBD1 and will fit on my F20B SOHC VTEC Motor? Or does the original F22a4 manifold fit on a F20B?

What everything should bolt up if you did obd2-1 conversion. Some sensors you can use the one already on the accord instead of the one on the f20b. I didnt use my map sensor on my h22a just used the one on the accord.

Prob is that the mechanic threw away my old motor since it was blown. So how do I replace the obd2 map sensor with an obd1?
