R33 gtst diff replacement

[BASHERnissan]

Hi again. My diff is, in technical terms, buggered. I was wondering if I could make a Frankenstein diff out of a diff like one of the silvia or 300zx diffs (not sure which one) as I would like a bit more taller ratios as I drive on Wellington highway everyday. Is this a possibility ? Or do I have to just buy a R33 diff ? They are 350 on trade me at the moment. 

Any other options I haven't thought about? Any advice is good. Thanks in advance RB gurus lol

3.7 and 3.9 crownwheel & pinion set from other diff can be bolted onto R33 centre.

Don't do it yourself. Needs to be set up properly or you will destroy it.

Thanks for the information! What do you mean by set up?

Gears mesh. When gears don't mesh properly, gears destroy each other. Getting the gears to mesh properly is a non-trivial exercise, involving careful assembly, measurement, use of engineer's blue, shims, crush spacers, torque measurement and other lovely things that are far beyond the capability of your average home player.

Get it assembled and set up by a diff/trans specialist.
