It looks like there are a couple of us that have running H6 -> Impreza swaps and a couple more working on it. I thought it was time to start a Q/A type thread for this type of swap. It has its own distinct difficulties that don't get discussed in the many STi -> *.* threads. This thread should also serve as a forum for those of us that learn something significant to share it with others.
So, what do you want to know?
Also, this should help keep individual's threads focused on their own cars and keep them from getting too far off topic.
Lesson #1 for me: The EZ30 requires two radiator fans to stay cool when parked and running. There isn't really space for this, but make room. Before I added the second fan, I routinely saw water temperatures of 220 and the car was always hottest parked at idle. After the second fan was installed, I hardly ever see 210.
