This particular engine was bought early 2009. Besides it was very clean (and came with iridium plugs) which showed the owner cared for the car. Here's pic of it when i received it
On the other hand, this is what you typically receive from the big sun...
It seems owners in Japan don't change the oil from one point on, when they decide they will scrap the car to get a new one. That's why (at least here in Chile) it's not easy to get a hold of a clean one. Overall I think the engine had the 50k judging on things like wear on the distributor rotor and the overall color inside (Not black! like the second one) which I returned to the imported BTW.
