List of aftermarket LSD for VLSD cars
I was doing a search on LSDs and it is hard to find this info... I am intending to compile a list of LSDs that require no open diff parts to fit in VLSD cars. I'll edit the first post as people add information. I would appreciate your help on this and I'm sure it will be easier for others to refer to when searching for aftermarket upgrades for stock crappy VLSD.
Quaife: Yes - 2 versions for both open diff and VLSD cars.
Cusco: Yes
OS Gikken: No - drop-in for open diff cars
Nismo: Yes - comes with stubs so can fit on both open diff and VLSD
ATS: Yes - versions for VLSD, open diff, and AT cars
Carbonetics: ?
Kaaz: Yes
Tomei: Yes
Let me know if I left any LSDs out or have any misinformation.

Quaife: Yes - 2 versions for both open diff and VLSD cars:
MT open - P/N QDF11L
MT VLSD - P/N QDF13L
Automatic Z - P/N QDF10L
Or if you happen to get a good deal on a 11L BUT have a VLSD diff, then you can cut the longer shaft 1.7" from the end:
or by the MT stub axle....
OS Gikken: No - drop-in for open diff cars:
If later year diff, may need to have machine shop open up snap ring hole or cut vlsd shaft, see here:
https://my350z.com/forum/8376966-post23.html
and
https://my350z.com/forum/engine-and-...tallation.html
Nismo: base model only, probably can cut stub axle on vlsd as well,but not verified.
the following 3 i belive will be just like the others and cut end, need to verify though:
ATS/Carbonetics: ?
Kaaz: Yes
Tomei: Yes

This applies to ATS LSDs. I am not referring to any of Carbonetic LSDs.
350/370Z 6MT with stock VLSD 109130
350/370Z 6MT with stock open differential 109150
350/370Z AT with stock VLSD 109160
No change in the axle stub is required. Actual parts number has more letteres depending on your choice (metal, carbon, or latest spec 3)
350/370Z 6MT with stock VLSD 109130
350/370Z 6MT with stock open differential 109150
350/370Z AT with stock VLSD 109160

I, personally, prefer clutch-type LSDs but it's really hard to find one that is silent. So far, Cusco RS looks the most promising as I've read many good reviews.

ATS LSD is composed of carbon plates, right?

Yes, LSD oil change is a pain in the neck. But the recommended oil change interval for ATS carbon LSD is same as the one for ATS metal LSD (after 2007). Metal LSDs are also available from ATS.

See here:
At drift events I loose only a few ounces of diff fluid when the diff starts to cook....
The factory Nissan design, the 350z rear diff has a breather hose, but if it gets to hot and pours out fluid the breather hose dumps it into the rear sub frame versus letting it fall on the road or track. The sub frame catches the fluid and there it stays for all the remaining Z years, driver unknowing he lost differential gear fluid..........
Subframe OEM breather line:
Target hard clear plastic water bottle:
I used this bottle because it was clear, hard plastic so it should hold the hot diff fluid and the top nossle design was easy to retro fit a typical barb fitting to attach my hose with little to no modification. It was about $8.99 so its easily replaceable.
Bottle cage mounted:
I have a single exhaust so I removed the oem heat shield. The remaining heat shield bolt studs were hanging down, so i used the drivers side rear stud with a lock washer and nut (M8x1.25), had to drill the water bottle cage hole a little bigger as well. I bought the universal strap water bottle cage at walmart for like $6 bucks. I then simply used a sheet metal self taping screw for the front water bottle cage hole mount location....the opposite side is the spare tire, remove the spare first. I carry no spare, so no biggy for me...one day ill file it down or replace with a nut and bolt but for now I'm good.
To connect the hose, i need to just buy or build a 1/4" to 3/8" barb fitting and run some hose......
REFILL THE DIFF:
I'm not done.....I plan on adding an AN fitting 90 degree elbow fitting to the differential FILL port, then an SS line going up to the rear hatch floor. I plan on drilling a hole and having a diff fill port with a AN fitting cap back there for super simple diff fills inside the car!
I don't need a diff cooler.....I'm not constantly cooking fluid, but my Nismo LSD does get it all going at drift events to loose "some" fluid.....if i was road racing many hot laps, i would most likely be designing a diff cooler, pump and all...
This set up will allow me to monitor (clear bottle) easily, re-fill accordingly, etc....
Thought i would share my progress thus far....

and
I worked a little today on my Diff fill port:
This is just mocked up....you can see the end on the right isnt crimped....once i determine the length I need ill cut and crimp it.
From left to right on that hose its:
M18x1.5 to AN10
AN10 90 degree crimped to
kevlar hose
AN10 straight fitting - not crimped yet
AN10 blue bulkhead break through and nut
AN10 black CAP
I drilled a pilot hole with a super long drill bit here and then opened it up big from the other side using a step drill bit:
I plan on filling my diff using this inside the hatch:
