I couldn't agree more with Sean and Kai. I was pushing out an estimated 307 HP at the crank 261.4 HP at the wheels prior to my last round of tuning. I've never replaced my turbo and don't see where it will be necessary till you go through and build up the bottom-end of the motor first. Kai is 100% spot on with his comments as well as his approach. Yeah, he's harsh at first but in the long run it's better than padded bull $hit. Kai has saved me some big $$$ with his experience and direct approach. He'll be truthful and not burn you just as long as you keep it real as well. And now...just my $.02 worth, research everything before you buy. Everyone claims to be the best, but they all have flaws in the logic. Look at your big-picture and buy accordingly. If you need to wait and save money before doing it, then don't rush and go cheap just to get it over with. If you know where you want to be at the end of the project and plan it out, you'll save time and money at the end.
