My focus is at 163k miles and I travel from Lake Elsinore to San Diego for work on average about 150 miles a day round trip I love my Focus and don't want to give it up, so I am looking into buying a used 2.0 duratec off ebay or elsewhere and cleaning it up a bit. My question is can I drop any 2.0 duratec or does it need to be within a specific year range. I have done work on my own car, but this would be my first engine replacement so sorry for the new guy question [boxface] much appreciated.
