Turbo, super charged, nitrous...shorter engine life?

[J.HIDALGO]

We all know MB's are known for engine longevity (at least the older models) . How does the addition of turbo, supercharging, nitrous and others affect the engine life? I would guess, all these outside forces affect the engine in a negative way. And even MB's are not inmune to the effects of these harder working engines.
I read in another forum that a new C kompressor sedan 6 speed is coming to Canada and , who knows, it may come to the USA in the future. It would be sweet to own one. However, engine longevity is my concern. Opinions?

With a factory MB, there is no concern with engine life. No kidding! The M111 2.3L was beefed up when they bolted the supercharger on it.

For longevity, many other things will wear out long before the engine itself, maybe even you...
