Maybe I'm not searching on the correct terms, but is there a nice turbo guide for the 2.7 like this one https://www.audiforums.com/forum/b5-models-69/1-8t-turbo-upgrade-information-93439/ for the 1.8?

I currently own a 2.8 A6, but will likely be purchasing an S4 soon and am starting my research for upgrades I want to do.
