I bought a set of Skunk2 stage 1 for $460 shipped...used once on the dyno. I am going with ITR valve springs and Crower Ti retainers, skunk2 gears and manifold, and a portmatched ITR TB. I checked around and did some research, Stage1 seems like the best cam for the street. Also, at $460 I couldn't turn it down.

The stage 2 will need a nice bump in compression to be effective, and some headwork...basically, it's more of a race cam than a street cam. More high end gains, though.
