the only vortech that i know of on a p5 is that of the Area 51 car and the wings west car and the WW car has about 15 grand under the hood, not too cheap. Along with the SC they have a 100 shot NX kit. serious stuff, but as far as i know Area 51 doesnt produce/sell a kit. And of course you could always find out what SC they are using and have some custom brackets made, but as for the rest of the 12 grand or so, thats gonna be a fun one to accomplish.
