does any one know if a 2009 A4 stock turbo assembly wit fit on a 2007 A4, B7 engine?

 

I would have thought it would fit, but that doesn't appear to be the case. Might want to check around to confirm.

 

The 2009 TFSI 2.0t had many revisions. I figure since that engine has 11 more hp and 51 lbs more torque, that something more than turning up the turbo boost, and adjusting valve timing was done. I wouldn't be suprised if there were some turbo revisions too.
