I was looking at Vast's website and I noticed that they had some manifold spacers for use when adding parts from different cars. I recalled that the RS4 and the A6 2.7t are very similar cars arent they? The 2003 are if I recall are similar at any rate. If I were to find a RS4 in a junk yard...very unlikely I know, but if I were, what parts could be stripped off? Would the manifold be swapable? What about the turbos, arent those k04's? The intercoolers are bigger I hear. What other parts could I look for that might fit the 03 2.7t?

 

In regards to the spacers I would either email Mike or call up to VAST and ask him.

As for the RS4 vs A6 I am not too familiar, but you may want to try the S4/RS4 forum.

Sorry I couldn't be more help

 

I think you can get the turbos, intercoolers, MAF, fueling,... not sure though...clutch maybe....
Note sure.... Could be more,

 

turbos would be a sweet pick-up
