Believe it or not I like them to stay factory with exception of ignition, exhaust and rims. Once you start changing things the reliability goes out the window. I think we all agree that I know that by now!! I can take the turbos out of mine faster than I can change the tire. Modifying is okay as long as you are willing to do more maintainence and not be bothered by down time. Speaking of which we need to see more pictures from Wayne!!!
