Title: Diff ratios
Post by: albitz on 13 May 2011, 08:23:10

Anyone have info on the various ratios fitted to different models please ?
Specifically, 3.2 auto/ 2.5 auto.

Just found Markjays info in FAQ which says 3.2 is 3.90/1, it doesnt mention 2.5 although 2.6 is 4.22/1.
Assuming the 2.5 is the same as 2.6 this would mean putting a 3.2 diff into a 2.5 would give a bit more acceleration at the expense of top speed and fuel consumption - yes ?

Edit - I think I have got that the wrong way round ? :-/

in general 3.45, 3.70, 3.90 and 4.22 can be made to fit.

do you need a way to work out which you have fitted at the moment ?
