10-4... do you know anything about the Quaife-esque WaveTrac diff?...

BTW, why when I Google Quaife, AutoTech still comes up as Quaife America... and they still have Quaife prominently shown on their main page?

nope - we had room to add one more LSD line to our offerings and went with OS Giken instead. I just didn't want to risk running into the same supply issues as Autotech had in the past when they distributed Quaife

Type of LSD: NISMO Lsd 1.5 set to 2 way @ 80%

Can i Change the Lock-up rate?: yes, 60%, 80%, 100%

Type of Driving you Do: Daily Driving and once a month Drift event.

Type of conditions you live in: Rain about 8 months of the year, dry for a few months. WA.

LSD Loudness: 5/10 while backing out or turning at slow speeds, after about 30 mins of driving the loudness tends to go away.

Overall Impression: I like it, not very loud, but you know its there when turning or parking lot pimping. You can def. tell the difference when switching gears and accelerating through a turn. Haven't taken it out to a drift event yet, but i will update when i do. One thing i did notice though is that on deceleration you FEEL the car slow down, (that feeling when you get off the gas) it's a lot more noticeable, but have no problems with it.

Recommend to Others?: This is a good lsd for daily driving and the once a month drift event. There will be noise but only when turning, very tolerable if you don't mind the noise. I like this LSD because it came with all available pieces needed to put on a base model. If you really are concened about noise though, do not get this one.

I've read this thread from first post to last. Its amazing how many people repeat everything that was stated not even 3 posts before them! Anyhow...Z1, if you still read this thread thanks for all the information. I will be ordering first part of the new year!

Z1, are you sure understeer and not oversteer? I would think having greater power to the rear under decel would induce oversteer and be desireable for drifting... Maybe I'm still not thinking about it correctly though. To my way of thinking the 1.5 way mode would provide more understeer during a turn in decel due to less rear wheel power.

In simplest terms, when under deceleration, 1.5 way allows the wheels to move at different speeds. This helps keep understeer minimized when entering a turn. On a 2 way, the wheels are always locked, so understeer is promoted

Ahhh, so during decel when entering a turn, a 2 two way diff will continue to limit the diff action between the two driven wheels making the the car want to continue to go straight, or understeer.

Thanks.

Z1 I recently bought a cusco RS brand new offline (ebay). Is there two types of cusco rs's for 350z's? I mean is there one for a base model and then another for a vlsd car? If so is there a different part #? I didnt see a part # on the original cusco box, but the top to the box is missing. I have an 06 Grand Touring with VLSD. Thanks

only 1 type for manual 1 type for auto

Can I have the two different part #'s? And where can I find it on the LSD itself? Or on the box? I cant find a part # anywhere. Thanks

iTrader: (564)

I am not aware of any part #'s stamped on the diff, sorry. Cusco part #'s are on white stickers on their boxes

Here is the part #LSD 252 L15 given to me when I purchased it. I just looked the box over and could not find a white sticker. Like I wrote before the top of the box was ripped off the box before I bought it. The person I bought it off of bought it new and never installed it. Then sold the car. This will fit my 06 (with vlsd) 6spd , right? Thanks for all your helpful info. Robert

I am fairly sure that is the one for the 5at. Z1 can probably tell you for sure.

LSD 251 is the part # for a manual transmission car, LSD 252 is the part # for an auto. The suffix of L15or L20 refers to how the diff was preconfigured from the factory (1.5 and 2 way respectively). This is changeable by rotating the internal cam. They all ship from Cusco as 100% lockup. By restaking the clutch plates, you can change the lockup. As I recall on the autos, there is an 80% setting. The Cusco manual diffs give you 3 possible settings of 60%, 80% or 100%

If you want to pm me the name of the person you got it from, I can see if it came from us and confirm the part #. The vast majority of Cusco diffs that were sold in North America for the Z/G came from us.

Since your car is a twin turbo, you can kill two birds with one stone and use that diff, by swapping your stock ring and pinion for one from an auto (3.3). Check out the private classifieds, or give us a shout, we offer them new:

http://www.z1auto.com/prodmore.asp?m...ne&prodid=3234

When installing the diff, you are going to need minimally new side carrier bearings, output shaft seals, and ring gear bolts, regardless of the mileage on the car. If you're going to swap the ring and pinion, we can offer all these, plus the rest of the install parts needed (all shown at the link above)

I can never win! I thought I got a good deal on it. I emailed the guy to ask who he bought it from. Hopefully he is wrong on the cusco part #. So for me to use this if its for an auto I need a 3.3 ring and pinion? Are the stub axles the same as what I have? Then I would also need a new pinion seal to? Thanks, Robert

Z1 Performance

iTrader: (564)

yes you will need an auto ring and pinion

output shafts/stubs are the same

ideally you want all new install parts - click the link above we have everything listed

I currently have a 3.5 ratio correct? What will the 3.3 ratio do to the driveability? Thanks

Ok Z1, the seller told me that he had reputable shop build his car with a vortech supercharger, exedy twin disc carbon clutch. That shop ordered the Cusco LSD. His car was a 05 roadster, 6spd. He said they ordered it for his car. He said he didnt know there was more than one and he just looked up the part # from online. The top of the box is missing. There has to be a way to tell a difference of the two LSD's? I would assume that sine the ring gear has to be changed that the actual size is different! I asked him if out of all the reciepts if the actual part # shows on it. I emailed that this morning. I hope he emails me back soon. I hope this deal wasnt to good to be true. I hope that it is for a 6spd. Thanks for all your helpful info, its greatly appreciated! Robert

I don't know how to tell the dimensional differences, sorry - you'll know when you go to install it, the ring and pinion won't be able to mate up properly

Greddytwin350Z

Is there anyone you could recommend that I can call from Cusco to ask what the exact difference is between the two versions? I mean there has to be a way to tell the two apart. The guy I bought it from seems like a stand up guy and he is 100% certain that the shop that ordered it, did so for his 6spd car. I would just love to be 100% sure myself before I take it to Frank Hill in the spring for it and my other goodies to get installed. As far as the 3.3 ratio, I rarely take the car on the highway. In my case wouldnt I be better off to leave the factory ratio in it? Again, thanks for all your help. Robert
