Help diagnosing turbo issue...
I can't seem to figure out what's wrong with my turbo. Can you let me know?

Doh
You should see the shaft play. Total shot bearing. Turbine must have smacked the housing. Poor turbine blade.

Haha! Yeah, I forgot to charge the system with oil (crank engine w/o ECU) :) Send me new K04s!
Just kidding. They look purty and I hope they run great (as I'm sure they will). Engine goes back in this week and hope to drive it next week. I'll keep you and the group posted with logs.

High temp materials are somewhat brittle...
There is a resonance associated with rotating a turbine beyond it's operating spec that it wasn't designed for. That K03 had 5k on it, MBC only with a rev-matched downshift to avoid some *******... as I said many times before, lol.
