I boughta book at Books-A-Million yesterday called Supercharging, Turbocharging & Nitrous Oxide Performance handbook by Earl davis and Diane Perkins-davis. Doesn't seem too bad, but I'm still not understanding all the formulas and what all I need to do to build a decent turbo setup for my engine. My goal (if possible) is 200 HP out of it. I saw where somebody mentioned 170 or so with a Garrett, and that's not bad at all, my caliber goes pretty well with 170 and its gutless CVT, much better than my Wrangler! Is it possible for 200 HP on pump gas with a turbo and/or some other mods to help it out some? I'm also needing help with actually sizing a turbo for it.
