Default Zero boost, Is my turbo blown?

Had no issues before. I was making 16psi no funny noises, no nothing. Now I have zero boost. Car behaves fine otherwise and is running a little lean.

I boost leak tested it today, no leaks. Wastegate is not stuck open, I can actuate it manually. None of the hoses are loose or have blown off, and this is confirmed by the boost leak test.

Any ideas other than blown turbo?

Turbo is kicked dude, pull the DP and look for the exhaust wheel... Bet it's not there.

it happened to me too, took the turbo ex housing off and found a random piece of sheet metal, that got lodged into the turbine fins, which it prevented it from spinning..

Turbo seized began leaking coolant and oil into the intake tract. I've got a used Td04 going on until I can get it rebuilt. Does anyone know if there are any wheel upgrades for the Td05 16g. It's one of the older ones off the STI. I'm told it's better than a VF39/43 so, I'm keeping it and rebuilding it. The wheels still look good, though the exhaust wheel was stuck against the housing.
