I Happen to have one of these...
It was the first bit of turbo stuff i scrounged up when i entered into the 6.2 diesel world.
I traded a late 80's Citation for a 6.2 that was changed out of a suburban.It came with an ATS kit,but the turbo wasn't usable.The wheels on the turbo were chewed up from stuff going through it.
After reading on this site i decided to go with the banks setup.I figured i would use it someday on a project where i wasn't trying to get a bunch of power.
