Actually that's not entirely correct. If it's a Torsen LSD, if you spin one wheel while they are both off the ground, the other will not spin at all. If you put it in neutral, spin one wheel, and while doing it get someone else to try to spin the other wheel the other way I think it would engage the LSD. If it wont let you spin the other wheel, then it has a Torsen LSD (which is what the Type R has).
