DavidN,I don't think it's a bad set up at all, it just takes some work to get it all to run just right. I have mainly, smoke, and egt issues right now. The stage 1 cam, Bts twins, and PP heads need the right charger to make it all work, and the 38R w 6x6 just wont' do it. I have a constant haze and smoke on tip in and in Ca that just doesn't work. I only have about 8,500 miles on the new build, so as you can see I'm still doing some tweaking. I built the engine with the intention on using the gtx4294r on it, I just wanted to break in the engine first, before going to crazy. I was getting ready to pull the trigger on a Sxe369s w gate, or the S468 which would put me at around $ 3,800 give or take a few hundred w gate, but now after what Charlie/KCTurbos just put out there, I'm gonna wait for this charger. I really like having the drop in BB type turbos, they lite a little quicker and should be some what cheaper to just bolt right up. I'm real excited about this one. I apologize guys if I got to far off the Op's original thread.
