One should realize that over-time any machine will wear and eventually fail. Majority of people on these platforms have gone tuned and full bolt ons and exceed 100,000 miles no problem.
A proper tune, and proper maintenance is all you need.
I dont think the average joe has anything to worry about and that goes for any enthusiast either.
Perhaps if you were tracking your car on a weekly basis running hot laps or 20 minute road courses then I would say you are really beating this car up.
One should realize that there are certain cards you are dealt with in the long run, and one of them may end up being turbo failure, but that can happen to even a stock tuned vehicle.
If you want your car to last forever, store it on a temperature/humidity controlled environment, fill all the mechanical bits with oil, and see what it looks like in a 100 years, otherwise enjoy your car
