Issues to ponder will be transmission strength, availability of 4.2 high performance pieces and most importantly,cost. The 4.2 tuner market is real thin and modding Audis gets very expensive. If you want upside, you can get a great C5 RS6 for about 25K.

I am familiar with this and aside from going rs4 internals for lighter weight or having custom pistons made there are no options...I'm not shooting for 350-400hp lol im just looking to gain response and a little bit more performance...not looking to go spending 3,000 for 25hp...if I wanted to do that I'd lower the compression to 9.8 and run 10 psi boost with two remote K04 turbos...The transmission strength is not an issue anymore than it is in an RS6 exact same transmission 5hp24a just has a slightly larger torque converter
