[urq] RE : WR Aluminum Engine

[Brandon Rogers]

I'd be curious about the history of the alum blocks in the street cars.
Putting some of them in road cars for testing for the rally machines
does not make sense to me at all.  I would think they would put some in
road cars maybe for homologation.  And road cars don't see near the
abuse of the rally cars - so I would think road cars wouldn't be a good
testbed.  Vice verse makes more sense IMO.  And would an onwer really be
happy about their car sitting for who knows how long while their motor
is crated back to Germany?

Very cool block - wodul love to hear if you can fel difference in
handling.  Anyone of the historians - chime in on history.

This aluminum engine came from a Euro UrQ. The WR code is listed in ETKA
(and take this with a huge grain of salt) from 1980 all the way through
1991. Rumor has it, that Audi put the aluminum engines in UrQuattro's
and a few 200 Quattro's to use the public as a test bed for the blocks
before they were used in the rally program. As the vehicles came through
the dealers for service, the engines were removed and sent to the
factory. The KW (Sport Quattro) and WR are both listed as alu engine and
yet the WR is also listed as an iron block. ETKA also directs you to a
parts data sheet 1-71 5/1991 for the WR alu engine. Engine internals are
nearly the same with the difference of longer head bolts (10 X 90 vs. 10
X 80) and a few other "aluminum engine" spec hardware requirements that
at quick glance, are only length differences.
