[V8] V8 Twin Turbo?

[Brian K. Ullrich]

I'm probably way outside the bounds of responsible spending, but does anyone
have any experience of a twin turbo conversion on a V8, a la RS4/RS6? I
figure it CAN be done on a 4.2, since the current RS6 application uses that
configuration, but what about a 3.6? 

 

If so, what of plumbing, injection, ECU, exhaust? 

 

Anyone ever heard of this being done? Just curious.
