If I just get the conversion harness, I would have to using an OBD-1 ECU, right? But what about all the other sensors and stuff? Distributor? would I need to get obd-1 distributor or keep obd-0 distributor?

<<who has done this recently.
yea, that is the whole point of coverting. if you buy a chipped p28, you wont have to worry about the knock sensor.
they should be fine. anything specific you are worried about?
yes, and you will have to repin your obd0 harness to accept the obd1 dist.

 

You'll have to change and add some wiring in the engine bay. I don't know all of which exact wires need to be changed/modified, but definitely at the distributor.

You will have to get these OBD1 B-series or D-series parts, depending on if you're going SOHC or DOHC:

Distributor
Injectors
ECU
4-wire 02 sensor
(this is optional) 92+ throttlebody, with top mounted MAP sensor.
An OBD1 vtec or non-vtec engine harness to salvage plugs from.

Supposedly you can just match up the wire colors from your EF wire harness up to the OBD1 engine harness, then just match and repin the pinouts to each plug, adding the OBD1 plugs to your EF engine harness.

this is all I know about this subject though, good luck.

You don't need the injectors, just leave the peak hold injectors and resistor box in place.

 

Didn't know that...thanks for the info.
