This has been about year in the making, but I have a terrible track record for completing projects so I didn't really want to share much until it looked like I had a good chance of getting it at least somewhat working. Well, about 9 months later than I planned that day has arrived.
As of earlier today I now have the EJ204 out of a 2003 (BL/BP) Legacy 2.0R running well enough to drive around in my 1996 OBS.
Here's a photo from "the good side" (where you can't see the giant rats nest of wires):
Engine management is provided by an open source engine management project called "Speeduino." Here's my totally hacked together testing setup:
Here's a video of (totally not) the very first start:
Raiding the Subaru parts bin: 2003 JDM EJ204 in a 1996 Impreza - YouTube
Yeah, that's a lot more like the 31st start.
You'll have to forgive me for starting in the middle. I'll fill in more of the back story on this as I have time to type it up, clean up the wiring diagrams and dig up old photos. For right now, I just wanted to share my results. I'm happy to answer questions.
