Wanted to give those interested a quick update - the car is up and functional. Everything suspension-wise works flawlessly.
I have run into some road-blocks with the ABS computer, and its integration into the ECU and CANbus. I have just ordered a VSSpro to facilitate getting a working speedo signal back, and I will work through the rest of the issues once that is going.
After that, I need to do some minor tuning for the change in exhaust that came along with the six-speed swap, and then I can really try it out. It will be at least a few more weeks before I can find time to get the VSSpro installed and see what other surprises the computer has for me.
I have also become a dealer for all DCCDpro devices, due to my positive impression with the company and their products while looking for a solution to this speedometer signal issue. If any of you need a DCCD controller, a way to create a speed signal output from the ABS wheel sensors (on any car, not just Subaru), or an advanced fuel pump controller for your high performance Subaru, Mitsubishi, or Nissan (or, most likely, many others) just let me know!
