there was a post not so long ago about about different fiffs

now my question is

my car runs the 3.6 diffs

im going to be using a gearbox out of a 2.9 xr4x4 which uses 3.9 diffs

will i have any issues

or will i need to use the 3.9 diffs



totally confused on all this

thanks

no pal, the box will be fine, its only if you run differant ratios front and rear.
e.g, my car will run a 4.55:1 in the rear, and a 3.64:1 in the front, so will need to adjust the step offs to suit a ratio differance of 1.25:1 between front and rear,

your setup 3.64:1 rear , 3.64:1 front is 1:1 equal diffs, therfore wont need any adjustment as the 2.0 = 3.9:1 and 3.9:1 so the step offs will be 1:1 std ratio.

does this make sence ?

have you got any spurious step off gears/chains knocking about bernie ?

i think ive got mine sorted with a 32/24 should be ok, just wonderd if you have anything else ? 31/25 ???????

25/31 is closer at 1.24:1 than the 24/32 (1.33:1)
Sorry mate no.

as long as you have the same diff front and rear no problem.

else VC will over heat and fail and maybie rodger the plannet gear as well then only RWD

ok

so as long as both front and rear diff are the same i shouldnt have any worries



whats the better diff to use as i have cjoice of both at the minute

3.6 or 3.9 and why would it be better

thanks

I thought the XR4 x 4 and cossie had the same final drive ratio....3.62:1....

Didn't think the XR4 x 4 was on a 3.9.....

3.9 will give you better acceleration, less top end....

the 2l models came with different diffs than the cosys or 2.9s

so think these are 3.9 then i thought they were 3.6 lol


not to bothered about top speed so ill stick to the 3.9 then

thanks

the 2.9 came with 3.6 diffs as per cosworth and has the same box ratios as a cosworth - just a different case

the 2 litre came with the 3.9 diffs but different ratios to a cosworth but in the same case as a cosworth
