He's already MPFI, no need for that.

You'll need a new ECU, but I would recommend that you convert to OBD1 as well. That means you'll need an OBD0-&gt;OBD1 jumper harness and an OBD1 ECU for a D16Z6 I believe (not sure on the code).

 

id also grab the tranny outta ur car, that would be helpful in the future....

 

i plan on useing my tranny.. lol would it work?

hahaha yes yes it will

 

kk

 

you will also need jumpers for the distributer to go from the obd1 plugs that come with the d15b to the obd0 ones on your harness.

 

the ecu you need is a p28

i didnt mean to double post either. i meant to edit the last one but hit the wrong button.

 

you can de-pin the plugs on the dizzy, so you wont have to cut them or buy the plugs for them.

 

can you explain how to do it? or can i search it and find it?

You answered yourself Grasshopper. Good on ya!

 

hmm idk if im searching the right thing or not but there is nothing..

 

my car has the engine harness from an 89 si so im not sure if they are the same or not. anyways here is how mine is:

Small plug- the colors match. you just have to take the obd1 clip from the engine harness side and re pin it so it will plug in

Big plug- all the colors matched but one, and that is the thick white wire. take the obd1 clip from the engine harness side and re pin it so all of the colors match except that one. and that should be thick white(engine harness side) to yellow/green(dizzy plug side)

hope this helps.
