Does anyone know if the above from an 89 turbo sw20 will work on an early 93 turbo sw20. Any thoughts would be greatly appreciated. Cheers

It's my understanding that the AP Power FC was created for the late 1992- 1993 rev 2 cars.
 
I used one a long time ago in a 1990 rev 1 and had to re-pin the ecu harness etc to make it work.
 
So yes I think it should be plug and play for an early 1993. What is the part number on your factory ecu?

What he said. Iirc they were originally rev3 powerfcs adapted to suit the rev2 as the pinouts were almost the same. So if its running in a rev1, then the rev1wiring wouldve most likely been modded to suit the ecu

Thanks guys for your help
