which diff?

[chris280]

Does it matter what age or model of XJ6 you take the diff from? I assume there are different ratios, which one is used as standard and what would happen if a different ratio was used? Also anyone any idea of how much a recon diff would cost?

The SEAC uses an IRS with a '3.06' ratio - giving
30.86 mph / Thousand revs - which at 6k revs
gives a theoritical top speed of 180mph..

So - don't get this one for you 2.8 - it will
be seriously gutless !!

Best try to get the diff from a 2.8 litre Jag
- it will probably have about the right ratio.

Yes. You want a 3.54 which are like rocking horse doo dah because all the kit car boys and hot rods have used them up. I was quoted upto £1200 for one! Other ratios are available and many do not have the PowerLoc LSD either. Absolute swine to get out of a Jag BTW as the whole of the rear subframe/suspension has to be dismantled.

The 3.08 was an option on the SEAC. Standard fit was 3.54 which gives a lot better acceleration.
