R33 GTS-T Diff or is it?
 

So I purchased a complete rear end awhile back and it came with what I was told a R33 gtst diff. These are suppose to have 4.x ratios and have 5 bolt flanges. Mine appears to fit the look of it.

Then problem is my internals don't seem to match up to the specs unless I'm reading the information wrong.

Can someone help me figure out what diff this is?

Crown wheel has 47 teeth
Pinion has 15
That equates to a 3.13333 ratio...I have not seen this posted anywhere in the r200 diff searches I've performed. Ami calculating this wrong?

On the crown wheel these #s are shown "S17:15x 3 6 28"

There's not a ratio stamp on the ring gear?

Hm.. I might have a pathfinder Diff... I'll have to take a look tonight but if that's the case... I'll be running 3.13333 in a stock KA so great gas mileage? haha.

My crown wheel says S17:15 x3 6 28

I tried googling it and got whack results. Also, I can't upload the picture for some reason.
