there are variations of the K04 with slightly different internals but yes it's essentially 1 RS4 turbo (or TT 225 turbo, but RS4's are cooler). it is a direct bolt on -- a K04 kit involves just the turbo, bigger injectors, a different fuel pressure regulator and a proper engine computer reflash (random gaskets and bolts too). it bumps power to approx. 240 hp/270lb. ft. just dumped in there. if you compliment it with a suite of nice bolt-ons you're looking at anywhere from 20 to 30 on top of that for both figures, at the crank.
i am so tempted to go with this in the future because it will be a reasonable step up in power and wrenching complexity but not too much of either. on the other hand, many people are beginning to peice together turbo systems for only a little more that put out alot more power. however if i were to go that route i'd need to source alot of stuff and do some custom work which i don't think i have the mechanical talent or know-how to deal with.
or i could just do what 90% of A4 people innevitably do, and look to the dark *biturbo* side.....no. must resist more weight and complexity....
ahhh right, i forgot all that pesky fuel mumbo jumbo
I say go with the K04, it seems like a reasonable step up in performance without all the complexity and trouble a complete swap would bring
