In serious though, what the hell do you want to do with a subaru over a tracker? Subaru has open front/rear diffs, viscious center + no low range = worse offroad than a tracker. As for putting a 2.2 or a 2.5 in a tracker? Bellhousing fit? Motormounts fit? Can you custom fab? Why would you put a crappy NA subaru motor in when there are other better choices you could make?
What is this thread about?
