viscous diff replacement for R33 gtst

[Kinkstaah]

Their webpage says this:

"Quaife ATB Helical LSD differential is suitable for Nissan R200 280-300Z / 200SX models and fits both S13 & S14 with equal length drive flanges"

To me this is the direct swapout for the existing Nissan helical, i.e the S chassis one?

No....the open diffs also have equal length shafts. I would presume that an LSD upgrade (ie, Quaife) would be primarily aimed at the open diff market, not replacing an already helical diff. I have no idea whether the open diff equal length shafts are the same as in the S15 helical diff or not. They might be. I really should go to the effort to find out one day.

The Just Jap listing for the Quaife diff lists it being good for all the S & R chassis diffs (and older long nose diffs too). With the only stipulation being the 29 splines. But of course, we all know that there's a bunch of different spline lengths across all that, hence my concern.

Hi im here again to try and find some information before i go and spend my hard earned buck purchasing the bits needed to upgrade my single spinning viscus diff to a cusco kaaz nismo centre is there any shops in the south east queensland or north eastern new south wales where i can take my diff and have the parts fitted and setup like preloads set etc as i would also like to replace the pinion bearings and front seal. Does anyone know where i can purchase new pinion bearings and seals so far i cant find anywhere who stocks them or there part numbers.

I would be grateful for any information so i can get full throttle and traction again

And don't bother trying to source bearings, seals and crush washers yourself.** That's what the diff shop is for.

**Not that it's hard. Nearly everything you want is available at JustJap anyway. And the other usual suspects.

You're in NSW, just drop it off at Smithfield Diff & Gearbox, the brothers there will look after you. They know their Nissans inside out.

Yes their website sucks, but they're not short on customers either.
