I would walk away from that engine and get a used runner. If it's been through a catastrophic failure you can bet good money that the bearings, crank and oil pump have been beat on badly. Once you start wrenching on it, you are committed to the cause - it's a shame it's only done 52K. You could get a whole truck for the $2k and have enough change to do a couple of worthwhile upgrades (this is where you might get lucky and find a 2.0 with a 5 speed cheap). Half a day with an engine lifter and you'd be back on the road.
