Ahhh cool,

That's one thing I was going to post a thread about "which oil to use for a mechanical diff".

Do you know which oils to use? Appart from the fact that I should change it cause the gearbox was never changed, so i should do the diff too. Plus I wouldn't mind loosening it up a little.

hi to all in this trend ive got a 94 r33 gts ive big plans for it at the mo the first thing ill be looking at is the suspension and work my way threw i guess the biggest thought on my mind is that my 33 is currently only free wheeling rear end ive heard from a few of the drifters round the way is you can lock a standard diff by welding your standard diff internals is this something any of you guys have attempted theyve spoken highly of this mod saying you dont get veriation from the switchn while drifting also i have noticed after they when turning in tight spots their rears do skipp massively and the cars tend to push foward rather than turn in cant be good for your day to day use or runnin to the super market also alot of 3 point turning so yeh is there such thing as the best of two worlds i wonder?????

I was told i had a locked Nismo diff of some sort, and in regards to wet weather, it is pretty bad, as when u hammer the pedal the rear end just spikes out, i found out the hard way doing a 360 around a round about, and thats with 4wd. =(

News flash, you have a powerful RWD car.. :P

I have the standard viscous diff and I have had one or two big "oh shit" moments when the rear stepped out on me. The only thing that'll save you in that situation is a diff that's completely open and single spins. Soon as both wheels are spinning you're going to get oversteer.

A locked diff will definitely step out, but they are predictable in the sense that you know they will *always* make you go sideways. Viscous diff - sometimes it will sometimes it won't. Sometimes it skitters back and forth as one wheel slips then the other.

R31 - locked diff will compromise your handling. Awesome fun for sideways action but cornering with a locker will always be slower than a proper mechanical diff due to inherent tyre slip. Slip is SLOW.

V8 supercars use locked diffs because they are cheap, not because they are the fastest way around a corner. V8's aren't the pinnacle of racing that's for sure!

:) kinks what v8s arent the pinacle of racing are you refering to circuit or drags last time i checked the fastest quater belongs to top fuel v8 draggsters not no rice cake and lemanz the tvr vanquish and corvetts are dominating not the exotic turbo snow blowers try switchin on the ol boob tube maaate yore dumming up the place :(

If you had read the whole thread you would have realized that he was referring specifically to V8 supercars and not to V8s in general. I think your looking a bit to hard for a V8 Vs turbo argument that never goes anywhere... :)

I'm pretty sure most people would think its pretty dumb going on skylinesaustralia and calling turbo's snow blowers. And your le mans argument is pretty flawed because as far as i'm aware turbo diesel audi's and peugot's are dominating...

    • Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...
    • Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.
    • Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents
    • I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.
    • One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
