Omega Diff Differences
« on: 27 February 2011, 18:51:35 »
Regardless of LSD, Is anything different about the diffs that come standard on the Omegas across the range?

Would a 4 cylinder diff fit a V6 and vice versa?

Yeah, I knew that there would be differences in ratios between auto and manual but 4 cylinder and v6 if both were manuals?
Alas I have no Haynes manual  :'(

Library it is then, unless someone wants to have a look for me please

OK thats really strange, the later 2.5 manual's having a 4.22:1 final drive but as per Rob's post it says that 2.6's have the 3.9:1 ratio.
