After the manifold to turbo gaskets failed (heat?) turbos were removed and apparently the thrust bearings are worn but otherwise the turbos are good. They've been on the car for maybe 50,000kms with quite a few track days, and i'm diligent with oil changes.
So, would that be considered early failure? Do thrust bearings usually go first? If not, why would they fail early?
334kws on -7 is high, could the tune be too aggressive? (I can post it when i get the car back).
