The S2000 has the Torsen T-2 LSD.
Torsen stands for Torque Sensing.
"Our" T-2's do have Torque Bias Ratio, but I have found no info on what ratio Honda decided to use in the S2000.
Read lots about it here:

According to the website mentioned above, the Torsen LSD is designed to use even ATF fluid.
But beware!!!
YOUR HYPOID FINAL DRIVE GEARS DO NOT!
That means you must stick to the recommended SAE 90 GL-5 oil.
(or simular viscosities like 75W-90 or 85W-90, but make sure it is GL-5 rated gear oil!)

No clutches or special fluid.

The Quaife in my civic specifically specs synthetic gear lube. Has anyone ever tried MTF in the dif? Be an interesting experiment since MTF is the dif fluid (well essentially it is) for all the honda FWD cars.

Not recommended IMO.
You try it first
With FWD and front engine cars (engine east/west) I'm not sure there is a hypoid gear set in the transmission to drive the diff.
With that set-up crankshaft/transmission/axles are all in the same "direction".
Straight gears (straight cut or diagonal) are less oil shearing IMO.

I'd look it up on Google. Go to Quaife's site.
In a FWD car with the tranny in there sideways, there is a ring gear and a driving gear that's built as part of the countershaft (so to change dif ratios you have to change the ring AND countershaft).
I'm not sure if it qualifies as "hypoid" but, the dif pumpkin looks the same in a Type-R and in an S2000 (within reason). You can't use some gear lubes in an FWD tranny because it'll eat the synchos.

After browsing online parts stores I found this:
That shows the final drive gear being a straight cut gear, not hypoid.
These parts are from a 5 speed manual Accord.
Those gear sets are less hard on their oil, less then a hypoid gear set IMO.

The Torsen T-2 works in a different way.
On wide turns it will act like a "open" diff (open as in .. you can see the gears
.. just a joke, this was discussed before)
and when one wheel lost taction it will act like a locked diff, that is the way I understand it.
2-way or 1.5-way diffs always are somewhat locked, because of the clutch plates right?

Quote from Wikipedia
A hypoid gear incorporates some sliding and can be considered halfway between a straight-cut gear and a worm gear. Special gear oils are required for hypoid gears because the sliding action creates extreme pressure between the teeth (see zinc dialkyldithiophosphate).

So is Torsen T-2 LSD 2way or 1.5 way ??
