It's also worth noting no two drivers drive alike. Somebody who bounces off the rev limiter daily, versus somebody a bit more conservative will have an impact on motor health/life. Adding boost will only exacerbate wear and tear.
You've got to pay to play. Don't add boost if you can't afford to rebuild if it blows up tomorrow.
