The thing is most people want all the power and thrill of high performance without the cost or issues that comes with high performance and running on the ragged edge. Very few are will and committed and for the builder/tuner/shop there are no accolades for engine failures by most even though they are doing what the customer wants and if there is not that loyalty between the two, the consequences are always greater for the one doing the build.
What is interesting is that I see as many issues or more with those that stay NA, the only difference is how much you are willing to pay!
