I went with Ghetto. It will be on my porch tomorrow. I got the stage 1 with upgrades to the dual b/b turbo, intercooler, BOV, TSBC, and 5th injector. I'm going to run the spacer so I can run the second stage up to 10.5 lbs. on pump gas. You will need a power commander (of course), and a clutch slave support for the heavier clutch springs. I'm putting in 70# valve springs, having the valves lapped, the cams have to be degreed (adjustable cam sprockets added). I'm also having the tappet shims set to the looser side of spec. Hopefully, that will give me more time before I need to check them again. I'm going with the dump pipe because I like the look of it, and stealth isn't too important to me. Word has it that although it's louder than an exhaust system, the turbo quiets the sound quite a bit. I'm not sure if the upgrades I'm getting makes it a stage 2 or not. Cost: around $6400 for the kit and upgrades, $140 for the valve springs, $312 for a PCIIIr (yes, a good deal), $500 to have the spacer put in and the stuff I mentioned, $200 for a gixxer 750 and 1000 fans, $70 for two Muzzy fan blades, $75 for an RPM crank case breather cover (gives more room and has an AN fitting). Add it up. I'm expecting 300hp on high boost. We shall see. Johnny Cheese is doing the internals and tuning. Doesn't get better than that. Motorhead answers all of my questions (stupid as they may be) and he sent me a PDF with the install instructions. They are also a sticky on his board.
