Kinks Posted August 16, 2013 Share Posted August 16, 2013 tailshafts don't chatter they just explode. don't ask how I know. not in an R33 thankfully it's probably suspension or subframe movement, lots of cars do it. usually it just means you've been a big girls blouse and haven't broken traction properly. half-arsed = chatter. 1 Link to comment https://www.sau.com.au/forums/topic/429679-nismo-2-way-lsd-vs-kaaz-vs-shimmed-lsd/page/2/#findComment-6973528 Share on other sites More sharing options...
cobrAA Posted August 19, 2013 Share Posted August 19, 2013 Considering a diff rebuilt kit i 300 shipped and labor to shim/rebuilt it would easily be 3-4 hours at 90$/hour. wouldn't buying an used cusco diff be a wiser move ?? Actually the question I should ask is : does OEM diff lsd break with time or they work just as good till the break and don't work at all ?

GTSBoy Posted August 19, 2013 Share Posted August 19, 2013 GTR or GTSt? GTR is a mechanical diff. Any mech diff (except for helicals) relies on friction to provide the limiting action. A such, as the plates/cones/whatevers wear they gradually stop providing the limiting action. GTSt is viscous. These things are marginally useful as an LSD when brand new and when presented with stock power/torque and stock skinny tyres with original hard compounds. Fast forward 20 years, add 150000+ km, add wider wheels with sticky rubber and wind up the boost or work the tits off the motor......and wonder why they don't offer proper LSD action.

donut_kng Posted August 20, 2013 Author Share Posted August 20, 2013 Tailshaft chatter is not the same as axle tramp, if you feel it you know what I mean it's pretty ugly- just as bad as axle tramp! Every cusco I have been in has been rough as guts although apparently these can be retuned to not be so savage. Got the Nismo 2 way detuned and put together in my R33 housing so fun times ahead should slap it in within the next fortnight Link to comment https://www.sau.com.au/forums/topic/429679-nismo-2-way-lsd-vs-kaaz-vs-shimmed-lsd/page/2/#findComment-6978729 Share on other sites More sharing options...

R31Nismoid Posted August 21, 2013 Share Posted August 21, 2013 I've had both - Shimmed is "not as good as", but I personally wouldn't say it's really overtly noticeable, depends how the shimmed diff is done, how many plates etc Link to comment https://www.sau.com.au/forums/topic/429679-nismo-2-way-lsd-vs-kaaz-vs-shimmed-lsd/page/2/#findComment-6979098 Share on other sites More sharing options...
BrynDETT Posted August 21, 2013 Share Posted August 21, 2013 would there be much difference between a shimmed r200 and a welded r180? debating on whether i should get my r200 rebuilt and put it back in ? welded has been great, just a bit of understeer Link to comment https://www.sau.com.au/forums/topic/429679-nismo-2-way-lsd-vs-kaaz-vs-shimmed-lsd/page/2/#findComment-6979109 Share on other sites More sharing options...
GTSBoy Posted August 21, 2013 Share Posted August 21, 2013 (edited) I'm keen to point out again that when R31Nismoid says "shimmed" he usually means a shimmed mechanical R200 like in a GTR. Other people talking about a "shimmed" diff are usually talking about a viscous R200, which is not a good technical solution. The two concepts (and the results) are not exactly the same. A shimmed mechanical diff is just a mech diff that has been tightened up a bit. A shimmed viscous diff is a crappy piece of poo that has had an additional wear surface put in it, where there isn't supposed to be one.

R31Nismoid Posted August 21, 2013 Share Posted August 21, 2013 My HR31 was also Mechanical So yes, i mean the Mech ones not the Viscous items which are just shithouse.

donut_kng Posted August 22, 2013 Author Share Posted August 22, 2013 I have shimmed about 4 viscous Diffs and only was truly happy with one of them, really have to play around with the shim thickness to hit that sweet spot of between not too savage and no peg leg action. This takes a lot of patience hence why I CBF anymore and just want a solution I hopefully won't have to revisit So viscous shim is only good as its good bang for buck- but 99% of the the time just know that diff will be coming back out!

benji-nz Posted September 17, 2013 Share Posted September 17, 2013 Hey guys. I'm wondering if anyone could identify this diff? (rather then start another thread). Planning an upgrade for the 32 and have spotted this; 4.3, 4 bolt rear R200 with 5 bolt shafts, s13 front housing.

Planning an upgrade for the 32 and have spotted this; 4.3, 4 bolt rear R200 with 5 bolt shafts, s13 front housing. Looks like a 2-way. Not sure of brand. It looks a lot like an OS-Giken. OS-Gikens should have the logo on the crownwheel bolt side of the housing. But really, it also looks like Tomei, Nismo, and whatever else. You really need to find some markings.

donut_kng Posted September 17, 2013 Author Share Posted September 17, 2013 Get a front on photo of the whole in the centre - will tell show more if its a 2way or 1.5 etc. Just an update, got my Nismo 2way detuned by a place here in Sydney- apparently reduces the harshness but maintains lock to improve drivability, and got some good oil put in. Popped it back into the car and cannot stress how great it drives. Gives the odd clunk when cold but once it gets some oil through it drives as nice as a viscous LSD but with instant 2 wheel action as soon as the clutch drops. Also gives the odd chirp on car park concrete which is no issue at all. No shimmed LSD no matter how good (i thought) it was, was even anything close to as good as this. Highly recommended I'm wrapped Link to comment https://www.sau.com.au/forums/topic/429679-nismo-2-way-lsd-vs-kaaz-vs-shimmed-lsd/page/2/#findComment-7023311 Share on other sites More sharing options...
