If you are looking for a Garret Turbo, go to anyturbo.com. They have the Blue Ribbon setup with a T3 or T3/T4 hybrid. I was looking at the Stage 2. But there is none available at this time, it is in the works. And with that I was also thinking to have the Turbo upgraded to ball bearing type from turbonetics.
