Really impressive. This isnt a swap. Ruf created their own V8 engine designed to fit in the 911. What makes it even more impressive is the fact that it makes 550HP & meets u.s. emissions. This 4.5L V8 makes the same amount of HP as Porsches 4.8L Twin-Turbo V8 in the Cayenne Turbo S, yet it is 80LBS lighter then the H6 it replaced.
