Don't use the search on here. Use Google and type "site:rs6.com turbo upgrade", or your choice of terms.

You basically need to upgrade the headers, turbos, injectors, pump, cooling, tune for $15k, then you will blow the auto trans, then you can do the 6-speed swap, then you sell the car...this is typical pattern
I love that we use exactly the same search example. We need a sticky that talks about searching this site!
