To: AUDI >All U.S. 4000 quattros from 1984-1987 should have A/C standard, and they >all come with the 2226cc 5 cylinder with 115hp. Didn't they increase the displacement from 2.2L to 2.3L sometime around 87? I think this also bumped the power from 115 to 130hp. Or was this when they brought out the 80-90 series. ---JCG.
