Being that theres not much performance enhancements that can be done(if there is let me know) on this car due to the tight fitting engine in the chassis, is possible to engine swap for a 07 RS4 4.2 V8 or 07 S6 or S8?

 

Hey my name is Rick and I have a 2002 A6 4.2. I would like to swap out my 02 4.2 for a 2010 4.2. I understand the 4.2 is not a big tuner which I'm good with, just would like crisper performance. Any help would be greatly appreciated.
