My 2000-2005 S2000 Honda Service Manual says the drain plug on the differential need to be torqued to 33 lb ft, same as the fill plug. I changed the fluid out for the first time a couple of days ago.

the spec on both plugs is 33 lb-ft, but as mentioned in the original FAQ, you'll probably have a difficult time fitting your torque wrench and socket between the diff and the beam you see in the pics to remove/replace the fill plug. Because of this, I just use a regular wrench, and tighten the plug with the same force as I did the drain plug. This is not a critical bolt, so better to under tighten, then if it leaks, give it a bit more.
