The engineers at Nissan know this...which is why it can handle a bit of boost. If you can afford to spend the cash for a build, it's going to save you a lot of time and headache later when/if you decide you want more power. You need to find the right balance of what you can afford to spend and reliability. If you don't leave yourself a margin for error, you'll end up broke like a few guys I've heard rumors about.
