I just got done doing a mixed bag of upgrades to my truck. I got the builders turbo kit from Justin and the fuel rails. I originally had a ats 88 kit and rebuilt that turbo with a 60-1 housing, wheel, and backing plate so I got a .59 t4 turbine for it for $100 and tial waste gate set to 10 psi but I will creep to 12 when I'm on it up a hill (from all my reading a 60-1 starts to get out of it's efficiency zone after 12). It saved me a lot of expense and since it was just rebuilt I didn't want to part with it yet. I was told the turbine is too small but I love it and I have a 5 speed so I like it for that. I got one of the eBay intercooler kits everyone gets, and an extra ebay manifold I welded up like Justin. For the pump I got an Omega moose because of the price difference ($300 if I remember right).
I thought everyone I dealt with was great and would recommend both with high regards. I no longer have to spin the truck past 2k to keep up with traffic between stop lights. I have 3.55 gears and with the taller 3rd gear I hit 10 psi at 1900. Egts are no longer as and issue, so far the max I've see is 950 up a big hill gunning it from a stop to 60mph which dropped as soon as I was up to speed.
