im surprised nobody suggested a supercharger with n2o, i know its not one of the two things your lookin at, however a supercharger you get into boost a lot quicker than a turbo, and for what you cant make in boost compared to a turbo you can make up with n2o. depends on what you wanna spend though, you can probably get a centrifugal setup used for a really decent price, but i would go new with the blower itself or rebuild for reliability, or if you want to spend a lil more and be real nasty you could always go roots type. its just a suggestion, i was just thinkin of off the line power, with nitrous you can have that, but with a turbo you cant as easily, but since your goin for lower et's then a supercharger wouldnt be a bad idea imho
