If by that you mean more heat is retained under the hood with a turbo, that is the point I am making. With all of the plastic parts under a modern BMW hood, because of sustained high temperatures inherent to an efficient turbo, I sincerely doubt the ancillaries will last as long as those in a non-turbo (not to mention the turbos themselves). If they have been re-engineered, it is likely for recycle-ability rather than 200,000 mile operation. Anyway, time will tell.
