[urq] RE : WR Aluminum Engine

[audijim at comcast.net]

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.
