Better ratio diff?

[JH32]

Just wondering ... if you put a different diff into the back of a GTS4 could you get better acceleration times?

If so, what sort of diff could you use?

Cheers

dude there already 4.3:1

[meggala]

and you need to change 2 diffs not one.

look for mods else where

[JH32]

oh

hehehe

cheers

Do you know what happen if I convert to manual n did not change my auto diff to a proper manual diff?

Is there any difference between R33 diff from cars with ABS and cars without ABS?

[meggala]

rianto your car will be fine with the auto diff if act it will probably accelerate a bit quicker cause it has shorter gears 4.3 as opposed to 4.1

is the abs sensor on the nose of teh diff .... i dont think it is

[rs73]

Thx for the info Meggala... I can then keep my diff, no point spending $$ on a manual diff then. That would not throw my

speedo accuracy away, isn't it??? Cause speed sensor is

not taken from the rear wheels?

MrMayhem, if the ABS sensor IS on the nose of the diff, then I might as well keep my diff as sourcing a 2nd hand manual diff I might end up getting a non ABS one. But I think ABS sensor should be on the 4 wheels, coz on the diff doesn't make sense to me, as a good ABS system should be able to apply different brake pressure to different wheels depending which one is locking.

oh, another "stupid" question....

is 4.3 diff theoretically stronger than 4.1 diff ?

or is it just affecting the acceleration and engine rev at certain speed.

[slip]

its just a ratio of how many times the tailshaft spins per revolution of the wheels.

[rs73]

Basically, if we do the maths....

4.3/4.1=1.049 (4.9% increase)

So if a manual skylines doing +/- 2500rpm at 100km/h,

then with a 4.3 diff it should be doing 2622rpm at

the same speed...

Also means top speed will be reduced by 5%...

But at 250 or 270km/h @ 7000rpm, anyone would be mad to

try that

well ive been in an R33 full of passengers on a racetrack doing 240kmh. 250 isnt that fast.
