Hi lads I'm putting a skyline in my focos and I could do with getting the diffs as close to each uver as pos / the rashiows crown and pins as a skyline diffs are 100% the same so no drag when in 4x4 . Any help would be fab

 

I do not fully understand what you are sking for but most people use the Supra diff from a non turbo supra (3.9). If you are taling about the Skyline gearbox then have a search on the recent threads. I thinnk with this setup you can use the std front diff.

I know with an after market box I need 3.9 drop gears in the MT75 to work.

I hope this helps.

MK motorsport make the supra diff fitting kit and Bara motorsport can rebuild the diffs.

I hope this helps.

 

Thanks for your input mate wot is a ford mt75 gearbox has a visgos witch will help with the mis match I think the ford box runs at about 60/40 split but I'm told today at a place that dose skylines that there 50/50 split . and if I run 50/50 spilt on the track it could weld the clutch in the transfer box as the diffs could be working against each uver . But they did say if I run it like 70/30 and run a oil cooler it should be ok

 

The diffs must match front and rear within 2 decimal places ideally.


You would get away with a slight variation but not much.


The ford system is nothing like the skyline system, do not mix up torque split with drive split.
