Alright, I have an A4 1.8t so obviously i have looked into uprgades, however i want an S4. What I was wondering was, since the new S4 uses two of the standard KO3 turbos, would it be posssible to replace both of them with new KO4 turbos and have the chip reprogrammed? If anyone knows, please inform me, that would be the fastest S4 ever. Thanks.

Sure. In fact, I think that's how the RS4 gets 380 bhp. They use a pair of K04's.
