It's not the turbine wheels, it's the vanes and vane mechanisms that can't stand the heat. Gas engines put out ALOT more waste heat into the exhaust (up to 1600*f) and the 19 or so moving parts for the vanes can't take the heat. There are only two gas cars to ever use a VNT turbo, the 1989 Shelby/Dodge Shadow and the 2007/8 Porsche 911 Turbo.

Diesels run much cooler exhaust temps in the 1250*f range.
