    Just changing the final drive ratio shouldn't mean you have to change the diff. The final drive ratio has all the power travelling through it - the splits for each wheel occur later - so just changing the final drive should not affect the splits to the wheels.

    but if you look at their pics, they are talking about a diff, to me it sounds as if the final drive cog joins straight up to a diff, or am I wrong?

    It is bolted to the back of the diff assembly (if I am correct, and I'm no expert!) but I don't see why that should make any difference? The power/torque is not split until after the final drive gear.

    1st = 3.583
    2nd = 1.947
    3rd = 1.379
    4th = 1.030
    5th = 0.820
    Final = 4.312

    and now have

    1st = 3.583
    2nd = 1.947
    3rd = 1.379
    4th = 1.030
    5th = 0.767
    Final = 3.722

    The internals from the Galant V6-24V, you would have to do some digging but Im pritty sure these would fit the VR4 box and give you the ratio's your looking for.

    Top Speed in 1 gear = 37.739 MPH
    Top Speed in 2 gear = 69.450 MPH
    Top Speed in 3 gear = 98.056 MPH
    Top Speed in 4 gear = 131.280 MPH
    Top Speed in 5 gear = 176.296 MPH

    As for the power, I think Im running more than anyone else here and hammering it more (no daily driving though) and they have held up to everything Ive given them including lots of 4000rpm launches.
    did you ever get anywhere with this? I have an evo 4 box on my legnum, gearing is all to pot! I also have a v6 24v gearbox, so just reading your comment I got a little excited to think I might be able to do some changes without spending money I don't have, thanks in advance for any help, I know literally nothing about gearboxes if im honest but I do love my car an do my level best to keep it out of the car cemetery lol
