RE: Rising Sun Motor's
I believe that they mention it somewhere on their site that occassionally they have to fill in their stock with wrecking yard motors.
Direct quote from their website:
"We also bring in top-quality used engines and transmissions from all over the U.S. to make sure that we have one available for your car."
"Let's set the record straight right now. Regardless of what rumors you might have heard, there is no point at which car owners in Japan must change their engines or junk their cars. Used engines from Japan are available because of the unique combination of three factors:
The climate in Japan causes cars to rust out in very short order, usually no more than 7-10 years. Anyone who has ever lived in the eastern U.S. can undoubtedly relate to this.
The Japanese Car Inspection (JCI), or sha-ken as they call it in Japan, is a very rigorous bi-annual inspection of nearly 50 systems and components on the vehicle. Once a vehicle begins to have serious rust, it cannot pass the JCI, and the vehicle is scrapped.
The average Japanese drives his car much less than the average American. Some estimates claim about 50 percent less."
So I figure with the lifespan of the typical L6 engine being 200,000 or more miles they have plenty of solid ones to pick from here in the US. That's my main gripe is that they lead you to believe you are getting a very low milage engine while you could be getting an engine with 150,000 or more miles on it. So don't pass up a local one for one of theirs.
