It's probably the same bare block, but factory turbo cars generally use
different compression ratios and different cam specs than their
naturally aspirated siblings.  Converting an S4 4.2L NA V8 to RS6
specs would probably require replacing almost everything in the engine
as well as the ECU, and probably a large part of the wiring harness in
between.  Lots and lots of money.
