What I've heard from a very knowledgeable person in the VW-Audi club Norwegen is
that all 20V Turbos use the same inlet cam, including the RS2. 3B, ABY and AAN
uses the same exhaust cam, the RS2 has a special ex cam.

His car (It's the widened S4 MTM RS that Ferry + Tom saw in France a few weeks
ago) has the 420 hp kit from MTM. It has the 7A ex cam among the many
modifications.

I can translate the mail he sent to the club with a lot of info on the cams in
the S motors.
