ok, so i dont know much about your situation myself but still tried searching it the other day for ya, search the ej207 on here, nasioc and on co.uk wrx sites. I found a ton of info and a few people that have done the swap, mostly because of the 8000rpm thing. that seems to be one of the major upsides to it.
well, good luck and happy searching
Matt, when I was researching this for him (the most that I could without digging too deep)I had saw that you would be the man to ask but didnt want to overstep boundries, so im glad you stepped up to the plate...props, also i was on nasioc earlier and noticed that there is a place in their just for swap topic discussion, so that would be another great place to look......
