Also i would love to get a pair of the ashz turbos he had up in classifieds last month :-). But i just got off the phone with Greg D. and hes pretty much convinced me to get the 530 . . . I would go with his turbo kit as he told me that it would spool up around 3800-4000, ( Also the turbos would prob. throw me off the track) But i would like to use my car at streets of willow and button willow and every other kind of willow. So I need something that will spool up quick.
