he can really verify that it's good. The ways I know of doing that are: Buy on this site, at least you can check out the seller. Buy from someone you know and trust. Buy one that's still in the car and can be started. ... The problem with these engines is that they are expensive to fix. You can buy a junkyard engine for $1000, then spend $3000 getting it usable. Since you say "drop it in and drive", this means that he doesn't want to spend a lot of time learning how to diagnose and fix it. I've bought 3 used Japanese engines, 2 were very bad. (I know, I'm a slow learner). I agree with others that a rebuilt engine from Kyle is the best way to go.
