If you go to 2GNT.com and use the search there, you'll come up with an assload of answers. As far as what you need to know, the kit itself was pretty straightforward install. I bought the Stage 1 kit for 2100 bucks and did the 'ghettofied' Stage 2 using a 1G sidemount. If you where to take into consideration the cost of gauges, stuff that needs to be replaced, and the 'ghettofied' Stage 2, I was looking at spending at least aroud 3K. That don't include getting a bigger exhaust. Me and a couple friends of mine, Fast420A and Skillionare on the board, did the install. A couple of things that you really need to replace from the kit is the Craptech FPR and those gay allen bolts for the manifold. Replace the FPR with the Vortech SFMU and use stock GS-T manifold bolts to replace the allen ones. Lemme know if you have any questions.
