We finished this build a little over a month ago and I am just getting around to posting about it. We have been using the Subaru engines for some time now, but this is the first one of our Subaru builds with a factory Subaru ECU and factory OBD-II port.
This build features a DBW throttle, OBD-II port (all the stock Subaru diagnostics are unaffected and can be scanned by the Subaru dealer or a good independent shop), check engine light, pre and post Cat o2 sensors, and all of the factory Subaru emissions and engine controls are left in place. The only change to the motor itself is a cold air intake in place of the airbox. The performance of the car was spectacular and the additional convenience of a factory mapped engine for AC use, cold start, climate changes, etc... just can't be matched...
