I spun a bearing in my 00 impresa obs and I have a complete donor car which is a 00 legacy outback with a 2.5 in it how easy is the swap? I looked at a bunch of other threads and from them I got that its mostly plug and play besides for a couple things. they both a auto trans but will the 25 fit the 22 trans? I know about the headers. would it be in my best interest to swap the ecu and complete harness for the 25 to the obs? if anyone has an exact guide like almost step for step that be great. I'm tryng to get this done asap since I don't have a dd now. thanks!
