I personally wouldn't buy one from Japan unless I was ready to at least take the head off and inspect the bottom end. You never know how long they've been sitting around and under what conditions.

I used to work at Import Auto Recyclers in Abby, disassembling write offs. The good thing about places like that are they actually test the motors before they pull them, record the #'s and the mileage. You generally know those motors were good when they were running right before the accident. They can also tell you where the car was hit (ie. a rear ender will probably have a decent motor vs. head on might have lost coolant/overheated etc.)
