This thread, or threads like this always turn into a pissing contest in some sort. He want's to stay NA, he doesn't want to go FI, also n2o doesn't make you NA. It might sound dumb why some people would want to stay NA when it will cost almost the same price as going turbo. But it's the same ideology, to why we like FORDS for being Ford, and dislike others such as Chevy and Dodge. He just wants to build his engine and Tom's info should be enough. Custom Intake Manifold, Cat's Cams from UK, and 3" Exhaust. This will get you into the levels of putting down what is rate on the fly if not over. Cannot look down on a well built engine can we?
