A boosted engine most likely won't last quite as long as an engine running stock power levels, however, longevity will still be quite good and most likely in the hundreds of thousands of miles before needing a rebuild. This of course is providing that the maintenance intervals are adjusted to reflect the additional power levels!
Speculation..speculation and more speculation..the only way to ensure longevity is to leave the engine in its original configuration...
