Hi Hotshot.
I am in PA and working with what is exactly the same motor. Mine is a JDM EJ20R. I have been to no less than 30 sites and cannot find one compatible with my ECU and year. All of my investigation over the last 3 months shows that the motor is out of a late 1996 - early 1997 Legacy GT from Japan. I am working my way through all the U and Australia sites right now. The issue I have is that the ECU uses connectors like the 2.0 N/A engines, not like any of the Turbo wiring I can find, which most label as B135-B137 in bulkhead wiring. The most accurate pinout I found is here: http://www.veloce.pwp.blueyonder.co.uk/ and only the ECU pinout,not the schematics.
If you find anything, or if I get lucky, please keep my contact info available and I will do the same for you.
Thanks,
Steve
