holy crap, sounds like you coulda been overspeeding the turbo. It will actually go rich under that condition as the compressor is pulling more air past the sensor plate than the engine is actually ingesting, and yes, it will quickly kill a turbo. The loss of pressure makes the turbo spin faster as there is less pressure on the signal line going to the wastegate per a given turbine speed.

You should consider doing an intake leak test before installing your new turbo. It's possible you may need new injector blocks and or intake gaskets. (hopefully not but worth testing)

Good luck
