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!!
