Stay NA or go to the Dark Side?

Both NA and FI have proven reliable, given a proper budget and knowledge. IF that were not the case, half the new cars coming out wouldn't be small displacement and turbo'd. It's all a big physics game. Not every motor needs to run a closed deck and low compression to run forced induction. But damn near every motor will have to be re engineered if that boost is turned way up. Keep boost pressure low, improve flow, and you get more performance per psi. Driveline reliability, good luck to those half shafts if your tires hook up. Our motor's as will only get so far without increasing displacement in naturally aspirated form. There are really only a couple things left to do. Exhaust cams, VVEL, increase compression, and octane. We don't have the luxury of Direct Injection. The JUN cam's don't seem like they are going to make a drastic difference looking at the specs. I'm sure I can get some custom ground ones taking it up just a bit further. Our Heads have a lot of unlocked potential if we could ever figure out how to take advantage of them.increasing compression doesn't make sense, because if we are going that deep, we might as well increase displacement. Regarding octane, E85, that's as easy as replacing a fuel pump, lines (if necessary), new injectors, and a tune. I like both options and they have their advantages and disadvantages. And thank the Car Gods we have a tuner market supporting both!
