obd2 engin in obd1 car
im putting an obd2 motor in my obd1 NX. I was just wondering what sensors need to be changed to make this motor work on the stock wiring harnest. and also do i need to get my dizzy cut to fit?

Old ass thread but BUMP this shit up.
I haven't found anything but dead ass threads like this.



I learned through people TELLING me to use the following from the obd1 engine:
-ignition coil
-power transistor
-obd1 injector harness w/ the obd2 injectors
-obd1 CST
-obd1 TB


The dizzy and it's harness HAD TO be used due to the harness and the OBD2 harness not working with the OBD1 wiring.

Distributor wiring is pretty easy. You can get rid of the external coil and use and SR20 internal coil/ignitor distributor or vice versa. The 99 or 2000 up and VE distributors all work the same as the OBD1 dist. I went the other way with my OBD2 and put the OBD1 external coil / ignitor so I could use a MSD 6AL for much better spark.

Also is the new motor a highport?

Distributor wiring links: (most of this shows VE distributor but they all work the same way)

INSTALL SR20VE DISTRIBUTOR IN A B13 sr20de harness

HOW TO: wire a ve distributor into a de harness!!

We all start from somewhere.
Just would be nice if people shared their findings instead of leaving a thread hanging
