your bigger concern should be melting pistons not the turbo.

Most folks consider sustaining 1500F pre-turbo near the upper limit, with 1600F for very very short bursts marginally acceptable.

Aside from absolute temperature another thing to consider is the response time of your particular EGT probe as well... with a slow probe and gauge you can be well into the dangerzone before you know it.

And just think, it's that hot after it passed out the head, and through the exhaust manifold.  Wonder what those pistons and exhaust valves fealt like?

The turbo itself generates a tremendous amount of heat. That turbo is not glowing from high egts alone.
