Let me know what you find out. That 2,500 rpm turbo kick-in is dependent of
turbo size, and what you want your engine to do. If you want useable, fairly
instant torque, you'll want smaller turbos that will spool-up quicker. The
neat part about dual turbos is that you can have (theoretically) the best of
both worlds --gobs of power at the low-mid band all the way up to readline.
I have a technician who specializes in Audis who recently rebuilt a V-8
tranny. Turns out very little was worn (I think it mostly leaked). So the
good news is a ZF repair kit is available --Have to find out how it went. As
to whether Audi made a "heavy duty" turbo-ready auto tranny, I'm not sure
(maybe Phil Payne across the pond would know). Audi did offer an S-8 in
Europe (V8 turboed), but I believe it was a stick.
