Have a search there was another guy looking to do this and it would be cheaper to sell your car and buy a S4.
Your other option is to run a larger turbo setup or max out your K04 set-up running a more aggressive map for your K04 but you will need larger injectors and fmic.
Oh and if your car is not Quattro forget the larger engine option.
