you speak of it as a new engine, and it is not. The engine was a JDM which you can never truly tell the mileage on unless you buy the front clip. I had a JDM installed and I didn't use the turbos that came with the engine due to they were froze. Next time though, I am planning on having Kyle or SGP build or rebuild my engine and do this thing the right way. But I got what I had paid for and it is still running fine after 1 1/2 years, no complaints. Good Luck, Dre
