I'm planning on doing a engine swap on my 93 Toyota pickup and a buddy of mine is going to do it for me he already has an engine for me that has 180k miles. Should I go with that engine or should I get one on eBay that is a JDM Engine with about 50k miles? Only reason I'm not sure it's because if I get the JDM Engine and it's not good I don't want to spend another 200 to ship it back
