I pulled a r200 form a 87 turbo 300zx today. When i cracked it open did not look like a lsd or open diff . I was hoping someone could help me id it

when i held the the drive shaft and spun one cv axle the other spun in the opposite direction

when i spun the drive shaft the only one cv axle spun

it did not have fins on the back of the case.

im hoping its a lsd or vlsd

all the r200s i came across so far you can see the spider gears very easy

thanks for the help

Looks like a clutch type LSD to me, but I'll defer to people who know more than me.

Nope. 4 pinion open diff. What looks like a LSD is just the carrier for the outer ends of the cross shaft.

Four Pinion Open Diff - Z31Performance

Thanks for the help guys was hoping it was a aftermarket LSD but look like I am going to have to keep looking

thaaaaats why I'm deferring to people who know more than me :stupid:

Never, ever buy a diff that's supposedly a LSD without having the seller pull the cover and send you pics.
