what LSD differential is this ?

[vtec-killer]

Hello people... I live in Dominican Republic and I have a AE86 with a sr20det and 240sx rear end. Reacently I decided to replace mi old diff, (open) for an LSD. I bought a noter complete rear end for 6500.00 pesos or 200.00 US. First I thought the diff wasn't LSD because the rear cover was from an open version till I rotated one axle, Bingo!. The new one has the oil inlet tho a side and a integrated speed sensor as you can see in the pictures:

the one at the left is the old one...

the lsd..

Back at home i remove the rear cover to see what was happening and yes it was a oem viscous LSD... and the gear ratio was: 4.08 49 ring, 12 pinion.



Now, mi question is: It's tis a different version of lsd or it was replaced?... it seemed like it was never opened..!
