This was discussed years ago when I had my 1986 Volvo turbo. The usual rule was to not drive at 3000 plus rpm and immediately stop and shut down the engine. I always felt the last slow mile or so to the house of office after exiting the interstate would let things cool down. The last I heard was that modern turbos now all have small pumps to keep the oil circulating for a short while after shutdown. Even without that, I was told to expect to repair the turbo every 100k miles. The car lasted 240k miles and the turbo still worked fine.
