Does anyone know how our turbine maps to the stock Audi K04 turbines? If ours is the same or smaller we may be able to leverage the already available aftermarket impellers.

Blouch turbo does work on the K04s that I have seen on the net. They do a 27lb/min compressor and an impeller upgrade for the Audi A6.

I'm just not sure of the specs on our stock stuff.

ΙΜΗΟ the Audi RS6 uses the K04-029 turbo which is slightly more efficient than our K04-025.
Our K04-025 is the same as in Audi RS4.
Right now i'm in contact with a tech shop in Netherlands ...he installs a compressor wheel from a garett T28 into our turbo along with some port/polish.
He told me he will sell to me a new K04-025 hybrid with the new compressor wheel,not just a compressor wheel.
it's pricey...approx 2.500 usd.!!!
