Thrust bearing Issue
I need to figure out the problem before I put another motor in. I need you turbo gurus to help me out here.

Anybody WHAT? You have gotten a whole host of different possible answers here and on M.net. What the hell do you want? It could have failed for any number of reasons. Without a full failure analysis nobody here is going to be able to give you any better guesses, and even then a lot of people are still going to say "it's the clutch."
Who assembled the engine in question and did they properly install the crank and align the thrust bearing? Was assembly lubed used? Was the oil pump primed before the first startup?

Actually having the clutch preloaded CAN cause premature thrust wear. Think about it. If the slave is pushing the clutch assembly that's bolted to the crank, then the entire assembly is pushed against the thrust bearing. So every time the car is started, the crank bearing face at the thrust, is pressed against the bearing w/o any oiling.
