Help required designing a diff

Well as i find it better to plan a project than just jump in im looking to find exactly what i need to make the diff of my choice.

Being that it will morethan likely be in a semi performance application in the future i thaught i would work out exactly what pieces i need that would hold up reasonably well.

Now Im looking at either 3.9 or 4.11 gears (i do bugger all country driving 95%+ city) with a 4speed auto, and afaik these gears were avalable in the R30/1 Skyline and pintara respectivly. Im assuming these would be BTR75 series gear sets.

For strength i would like to go 4pinion 28 spline, however iirc this was only avalable in 78series.

Now so far these are the parts i think that i would need.

Stock EAII (origional 3.08open) diff housing
28 spline non ABS axels.(ED==>)
28spline LSD 4pinion center (XR6/ED LSD/V8 diff)
4.11 diff gears from pintara.

Does this sound right?

Cheers.

Ill take it as a complement i think.............

Re: Help required designing a diff

All models from EB onwards (inclusive) have 28 spline axles. Any 28 spline axle LSD from EB onwards will be 4 pin. Any ratio from 2.92 to 4.11 will fit a low ratio hemi, but discuss the best ratio to suit your application with someone running an auto, as lower ratios will not always guarantee better times. It will come down to the work done on the engine as well.

If you're not driving a manual you're really just steering.
