That engine is a bit of a mixed blessing - it's an awful lot of engineering for 
just 20bhp over the 10V ur-quattro.  Plus some operations are a downright pain 
- have you seen the instructions on how to reach the distributor, for instance?

I'm not sure what the upside performance potential is.  I don't think I've seen 
a 20V ur-quattro in the UK that wasn't absolutely stock.  The price, for what 
are comparatively minor improvements, is pure insanity - 20V urqs trade at over 
GBP20k ($32k) compared with MB urqs like mine at around half the price.
