the VR6 is the hot swap in the audi now.it mounts longitudinally, allowing a big turbo on the side, modified intake manifold, where the APB 2.7TT barelly fits in the car and putting a big single on, or bigger twins is harder to do, manifolds are more difficult to make, and quite frankly there is more out there for the VR6’s. this engine was used in USP’s old 9 second mk3 Jetta drag car. all they did was take that engine, put a new intake manifold on it, and get rid of the old T74 for the new 67mm billet turbo, tune and go… and the S4 does it on BFG Radials
fits like a glove.
