Oil For Nismo 1.5 Diff

[tridentt150v]

Would the Castrol SAF-XA be Ok for a Nismo 1.5 diff? Or other recommendations pls...

Mild tune 280rwkw, street not race, '98 GTS2.5t.

clutch type diffs need an LSD oil. The standard R33 diff does not need an LSD oil because the viscous centre is a sealed unit.

LSD oil has friction modifiers so the wet clutch works properly, if you fill with a normal oil your diff will shudder.

Check to see if that Castrol one is suitable for limited slip differentials.

thanks, I'll check it out

i'm putting motul in mine (its the same oil nismo use aparently)

[tridentt150v]

^^^^^better still, any idea what weight?

[joeyjoejoejuniorshabadoo]

i'll find out when i buy mine from the motul rep

[tridentt150v]

thanks, keep me posted, keen to know.........

[Gts-t]

Couldnt you just order some nismo stuff thru repco or one of link international's retialers. Thats what i plan on doing

[tridentt150v]

Hard to get, not even sure what grade or weight, I'd need the brand grade and weight first. ie Motul Gear Oil 90 PA SAE90 or Motul Gear Competition 75W140????

I'm thinking that the Gear Competition would be the go, but would like to be sure, tearing the teeth off a diff is NOT on my list of things to do..........lol

[joeyjoejoejuniorshabadoo]

weird.... why?

[JaseR33]

Standard nismo oil in the LSD kits is weighted 80W-90. I'm gonna have the same problems sourcing oil after i install and run in my diff. Keep us posted how you go with alternate oils.

I got no heart.............

Can anyone tell me the capacity of a Nismo diff.

A std diff is 1.8 litres, i just did my Nismo and it only took 1.35 litres and thats after I double checked!!

It flowed out the fill hole twice so it has to be full, but I'd like to have my figures confirmed - peace of mind and all that.

[EJD001]

what grade of oil u using??

im getting a OS giken 2way and the oil its spose to use is 80w250

[tridentt150v]

Motul Gear Competition 75W140

80-250 doesn't sound right, didn't think you could get the viscosities that far apart in an oil??? Maybe 80w150????

Since when is a std diff 1.8? 1.3 is on the money unless you have an extended backing plate (trust)

Sorry, i went off what a certain well respected shop told me when they looked it up - when i was buying the oil.... pretty sure they said 1.8 - but it could be my memory, maybe they said 1.3 - I can't be 100% sure. Then I didn't look it up anywhere to check either.

BTW I just did a 1500km weekend and the Motul Gear Competition 75W140 worked fine, no problems.

And EJD, apologies, 80w250 it is>>>sounds like a good broad viscocity base, would handle a lot of situations.
