Hank touched on something that is beyond most people's control, and that is the quality of today's pump gas. How many times have you known of someone that has gotten water in their gas from a local gas station of just crappy quality from one batch to the next. Its times like that when electronics is worth their weight in gold, and can save your engine before you even knew there was a problem. I'm starting a killer turbo 250 build myself and I wouldn't consider it without all that stuff in place.
