STS has done all of the research/leg work for you, with GREAT gains. personally, i'd mimic their setup which would give you the same types of gains. i'd purchase the same turbo & wastegate (which you could find cheaper used/rebuilt/or just get it new), and then have a shop build the exhaust/intake piping for you. i'd also find out what type of tuning/fuel system they use, and get that. i'm sure you could copy that kit for half the price and have the same results.
like i said though, it's hard for just anyone to tell you what size turbo is ideal for your application. find ANY KIT designed for your truck (doesn't necessarily have to be STS), and save yourself the money but putting the kit together yourself, using their specs. just my 2 cents.
