Here we have a pair of (used) RS6 Turbos, picked up on the cheap as they need a refub but they are part of my "Phase 2" plans for the RS4 so will be stored until required. Plans are to have them modified to fit the RS4 and a Stage 1 modification to them which should yield 600+ with associated mods. Turbo Dynamics will be the company who modify the turbos as required.
