AFAIK the AAZ was available only as the 90hp turbo in the USA. But in Europe, there were the 60hp NA, a 75hp low pressure turbo (the follow-on to the Eco-Diesel), the 90hp that we had, and a 110hp with a scrolling turbo. VW's experience with the 110hp led to our current 140hp common rail engine. Dan Snyder - the Fancy Dancer
