Re: Alloy block on ur-q's

[Dave Eaton <dave.eaton@minedu.govt.nz>]

as far as i know, there ain't no such thing on ur-q's.

the original alloy block for the 10v (330hp) group 'b' (a2) cars never saw
production in ur-q's.  the alloy block was also used for the famous narrow
angle 20v head which was homologated and saw production in the (305hp) sport
quattro.  the head lives in every 20v installation albeit without the radical
cams.

so as far as i know, the only alloy block audi i5 is in the sport.

i've scanned some pictures of it (block) if you're interested...
