These are all good points. If we are really worried about reliability, we shouldn't be adding a turbocharger in the first place. It sounds like the turbocharger is the best bang for the buck. An X51 swap won't give near the same amount of power, and a 997 with supercharger motor swap may give similar power but is going to cost a lot of bucks. Am I correct? Please let me know, I really would like to know.
