I think it should have an LSD. The way to tell is jack up the rear. Spin on of the tires by hand, and if the other spins in the opposite direction then you have LSD.

I'm sure by now jacking up my car and spinning the tires will not let me know if I have a LSD or not. my car is almost pushing 175,000 miles. by now I wouldn't be shocked if I have a LSD the clutches are worn.
I am going to do the burnout thing with one tire on grass the other on the street
but I am still curious as to why the rear of my car pulls to the right
and if it is a open diff why am I leaving two tire marks when I shift and launch

hmm... how 'bout you first look for the tag on the drain plug, ... then pop the pumpkin open and take a good look.... (this would solve the ****** problem... )
...BTW, if you look at how an OPEN differential works, if the outer casing remains stationary (ie. the propshaft is NOT turning) and one side is rotated (ie. spinning one tire by hand while the car is up) then the other tire WILL spin the OPPOSITE direction.... (seriously, look it up or something guys... )
...as for the functioning of LSDs, no bloody clue have I....

There was no LSD option offered for the '86 Sport. I'm not sure about an LSD option for the '87 Sport, but I'm not going to disagree with you.

open diff, One wheely peely.
LSD, can spin both wheels when both tires are on similar gripping pavement.
Locker, Spin both tires when one is on slippery (or in the air) and the other has traction.
All my cars with open diffs do one wheel peel outs. If you can put power to both wheels with an open diff then there is no advantage to a LSD. Also, WITH a LSD you can still spin only one wheel if there is too much of a traction difference. Do some time serious off roading (preferablly with a 4x4 not the rx-7) and this will happen a lot. My 4x4 has a LSD and the preload so high I can't turn one wheel by hand with the other wheel on the ground (trans in neutral brake off). My rx-7 has LSD and the preload is so low that it basically freewheels under the same test. It still can spin both tires though so I'm good

Hey you guys cant all go by what model your car is. My 90TII has no tag but its a LSD. Ive seen lots of LSDs w/o tags and Ive seen stock gtu that were open.
And actually I just got a clutch diff for my 86. It had a tag and both halfshafts spun the same way when the diff was out on the ground

ok so I tried this
I put one wheel on a bunch of dirt that was on the road and the other was on good pavement
spun the tire that was on the dirt
so I guess no LSD for me
but I still don't understand then why with my open diff when I dump or shift I spin BOTH tires and leave two nice big tire marks

it was like the wheel on the dirt was slipping while the wheel on good ground did almost nothing no spin no power
while a locker would try to spin them both

Last night while installing the exhaust I noticed the yellow tag on my differential So I guess this means I have an lsd like ive suspected this whole time. So is mine still a base with an LSD option?
