I'm looking ahead to when I may have to replace my stock turbos. Can anyone share experiences with what they have done with the A6 2.7T? Hybrids or K04s? What other intake or exhaust changes were necessary to accommodate the different turbos? Change in performance and gas mileage? Approximate costs?

(Also posted in the turbo/supercharger section of the forum.)
