Why do our engines blow up?

[steven88]

Okay guys...I originally purchased this car to do bolt ons and tuning...and keep the stock turbo...I never planned on going big turbo or even exhaust manifold w/EWG for that matter....just your avg enthusiast with 2 grand to spend on bolt ons....but now I am having second thoughts on continuing with the speed 3

Theres just too many threads that I've seen with people blowing their engines...whether its stock or highly modified...this can't be normal, can it? I understand Mazda designed this engine to be at 263/280...but come on now...some people are blowing from just an intake and bov....whats up with that? Is our engines that weak? Bad tuning from the factory? Bad PCV valve?

So I'm in a dilemma here...I love my car to death...its given me no problems what so ever...not even a single rattle from the dash....and I love the power and the way it handles...but I'm just seriously concerned about the engine blowing....and when it does, I have a feeling mazda will not cover it under warranty...heard too many stories about warranty claims being denied...I just feel like parting out and getting another platform....even though I will lose money on depreciation on my ms3...its definitely going to save me in the long run because a new engine for the ms3 will be hella $$$$

What should I do guys? Keep the MS3 and not worry? Or EVO X? 370Z? haha
