I was told it was new at the time I got ahold of it, and from the way it looked I can believe it. Though, I know I could clean up the turbine housing to make it look new too.



I hate to say it, but you'd have been better off getting a new cross bearing assembly with watercooled bearings and having the housings/wheels installed. THat would have increased the longevity 10-fold at least! AND it would virtually eliminate the need for a cool down period on anything other than hard running. Call the guy up and ask him how hard it would be to add a watercooled bearing assembly, normally it only costs like $75-$100 add-on when getting a T3/4 turbo. Since he's rebuilt the old bearing he can use that on a rebuilt turbo and sell you the water cooled assembly for maybe a bit more....hopefully.

I always gave about a 1 minute cooldown after beating racing my car before shutting it off, but normal driving I just waited maybe 10 seconds and shut it off. I did have the benefit of an EGT guage and my criteria was letting the temps drop to 400 degrees C or lower at idle after getting off of it, both Turbo or N/A.
