I have a 94 Probe GT (auto-trans) and the original engine is leaking oil in a place where fixing it would be as much work as dropping in a new engine. I considered a KLZE, but that is boring. I was thinking it be awesome to drop in a 3.5L or 2.0L Ecoboost engine. Does anyone have an idea how possible/difficult this would be? Any thougts on this would be appreciated!
