Sounds awesome man. I'd love to see some pictures. I should have elaborated but I have my answer. I was abbreviating for Antilag. (ALS) Since you're endurance racing I'm assuming that there was none involved

That's very similar to T2 here in the states for SCCA.

There are a number of users that have lost the stock turbo on the USDM version as well.

That is why I am asking ..

Is that an Inconnell turbo or not ?

RS has Inconnell fitted as standard, GSR as an option (HA is standard)

I think USDM only use Inconnell ?? I'm not sure on this ..

When the dealer showed the owner they only showed him that the shaft was broken by just showing him the turbo. They didn't disassemble the turbo to show what part of the shaft broke so he doesn't seem to know. He did say that the dealer was spinning the exhaust blade so I guess the bearing was in tact.

I believe that I read that they are inconel in the states. I havent tested them though. Inconel is supposed to be able to take a VERY HIGH heat level, however it seems not enough in many cases (that is of course it is actually inconel on USDM units).

In the cases we have seen firsthand, the turbine blades deteriorate and disintegrate unbalancing the turbo and giving it a whurring sound. The turbine blade pieces can end up getting bounced back all the way to the cylinders and contact the spark plugs.
