Some do… I got base s14 with vlsd that was sold with an SE emblem - I am just glad it didn’t say “type-r” on it… 
If you guys want to check the model factory features, check vin / model # on the firewall then look up the specs at http://garage.projectraine.com/
Click on guides -> VIN / MODEL ID DECODING…
Or look for orange VLSD sticker on the side of the tranny, burnout w/tiremark tricks to confirm this (in case it was swapped out by one of the owners for an open diff before sale).
