Im thinking to to convert to obd1 and go with d15b in my 91 mpfi DX

Just want to gather my thoughts together to make sure i understand what all i need to make this thing run.

1. Repin my, mpfi converted, obd-0 to obd-1 like so:

and plug in a p28

2. Cut the resistor box out with all the wires joined and run obd-1 injectors

3. Motor will be direct bolt in with my zc tranny

IS that it?

1. Do i need a different driverside engine mount?

2. Anything to change around with distributor or any plugs for that matter?

3. how many plugs will be different?

4. Anything else im missing? I need this to be as easy as possible since i dont have much more time to screw around.

5. And what do i do about the o2 sensor

 

Off topic i pm you a couple weeks ago about a question and never heard back...que pasa...!!!

 

going to need to run an obd1 dizzy, which has different plugs. You could snip off plugs from an obd 0 dizzy, and plugs from an obd 1 engine harness, and make an adapter harness for your dizzy. As for the o2 sensor, obd 1 has a 4 wire o2, while obd 0 is a one wire, so you will need to run those new wires to the ecu.

 

wil i need to switch dizzy wires around tho? I can always make a plug out of anything, as long as i got the right wire order, but where do i get that?

And i think d15b had one wire o2, so thats confusing as well, i guess if i add a 4 wire o2 at least 3 new wires will run into ECU, which wires are those and where do i find it?

BIG: pm me again i was out of the country
