I think Phantom Grip is the only option for D series...and it's better than nothing, from what I have been told, but not worth the money.

dam 2g's there is no way i can just get the differental and install it on my b16 tranny?
The type-r has a torsen limited slip, i don't know who makes it. The other limited slips (all factory non-type r trannys) are usally made by hitachi, they are totally different. They are clutch pack limited slips. Hitatchi is the OEM diff supplier to most japanese carmakers. They also make the performance clutchpack diffs but they are based on the same housing as the open diffs so they are cast and have only 2 pinions. All of the aftermarket clutchpack diffs (kaaz, cusco,ats) CNC new 4 pinion housings so they have more space inside for largers clutch discs. They are less prone to failure since they were designed from the ground up as LSDs and build up less heat. For the street I would recommend an aftermarket 1.5way clutchpack diff or a torsen. If you find a good deal on a jdm lsd tranny they are worth it but remember that clutchpack diffs wear out and you should try to get a rebuild kit (viscous and torsen diffs should last a long time). I have heard some bad things about phantom grips but they are so damn cheap (i have seen them new for less than $200) that it might be worth it to some people. I hope that this helped.

the primary difference between the 3 is this:
clutch-type: cheaper, but wears out quicker due to the friction-lining based nature of them (think of it as, of course, like a clutch or brake pad). very effective, however. very good all around LSD
torsen (or gear-based LSD). not mechanical slippage so there is no wear like clutch types. very expensive (compared to clutch type). for street duty they work.. if you are gonna drag race i would recommend a clutch type. with hard launches, sticky slicks, and a strong clutch, you can actually break the teeth on these types.
viscous: they use a thick fluid.. kinda like a heavy oil to lock the drive shafts. they have the long-wearing properties of a gear-based LSD, but without the pront to breakage under high load. these will be the longest-lasting type of LSD. they are very expensive however (moreso than gear-type), and they usually end up "hunting" for traction leaving the car to wander under hard throttle.. or causing a delay in shifting power to the outside wheel. because of this they are not as effective as gear or clutch type lsd's, but they have the best longevity.
our 1997 Nissan has a viscous LSD in it from the factory.
the ITR and new SE-R both have gear-types, but most other factory LSDs are clutch type.
hell.. even the porsche 959 had a clutch-type center differential
