It only chattered around corners tight ones, and when first started out cold. The unit is in fine working order I used the GM LSD additive and found it to be as quiet as OEM but, did not realize that it would take away from some of it's performance characteristics. I was using the LSD additive from CRC, it worked well and you would only here it under tight cornering and when cold. The rear is new and has had two oil changes, first was brake in and 2nd is with the GM additive.
I pulled the rear the other night and removed the aluminum cover to inspect. All looked good I just set my backlash a little tighter and will reseal it back up and add new fluid.
I have some of the new LE stuff that replaced the LE 607. I was going to use that and go back to using the CRC brand LSD additive.
The rear is my avatar pic it has only 480 miles on it.

 

[QUOTE=KeeblerElf,Nov 28 2007, 08:54 PM]Thanks, that does help.

 

Alright Red, I'm not going to lie. Once again your great replies pulled me into another thread I would have otherwise never been in. With that being said, after reading your above reply, and reading how you said "and when the diff is cold I avoid accelerating while turning". I'm not going to lie, when I'm getting up for class in the mornings and driving to school, its usually cold out and theres one turn where it's fun to get the back end out a little bit. Its not like I'm doing huge donuts, I might get the back out at a 30 degree angle or so (lack of protractor be damned). Am I doing excessive premature wear on my diff? I do not want to go breaking anything, but I can't imagine slipping out one turn when it's cold is worse on it than a day's worth of autocrossing.

One more, I have a 00, as do you, and my diff whines like crazy under deceleration. Is there anything I can do for this? Im 90% sure it is not the dreaded (and all to common) clutch buzz, as it's coming from the back of the car. And Im no mechanic, but Im pretty sure the clutch ain't back there. Anyways, would a change of diff fluid help that out? It has 22,000 miles on it and Im not sure as to whether or not the diff fluid has been changed yet. It may have, but Im not sure. Ill look into it in the morning. Thanks for the response to come, you're great.

I to live in a wooded area too (small town) I have to drive about a 1/4 mile at 5 to 8 MPH before I get to the main road. With the CRC stuff it only made a little slipping sound when I made the first turn onto the main road. That road is a 40 MPH road that I drive down another mile on, before hitting the 50 MPH road. By the time I make that turn it is pretty much stock sounding. The thing works like a charm and is a blast to drive with I find myself going around corners a little faster than I did before to get a little rush No crazy chance taking but, just a little faster

I will Email Kaaz to ask about the LSD additive from Gm. I talked to a rep from CRC and they said that there product is made for clutch type LSDs and is safe to use with the unit I have.

Thanks for all the info, it has been very informative about the LSD in general.
Kaaz has a new "solid LSD" that they make for the Nissan. Soon the clutch kits will be available for our Kaaz units to upgrade them to this new type if you like

 

The reason I don't accelerate while turning is because I have the KAAZ LSD, and when that baby's cold, turning and accelerating at the same time is downright nasty. With the OEM Torsen it's not somehing to worry about. Just warm the car up thoroughly before driving it hard. It only takes a little time, and it makes life easier for the equipment.

LOL, be careful sliding the tail out on cold tires.


I wish I could diagnose differential whine on the Web, but it's tough. The clutch buzz comes more from the front of the car, and sounds like something is rattling. Nothing like what you'd describe as a whine. My best guess is that you're probably hearing the differential, but to find out if it is whining excessively you should probably have someone else (reasonably knowledgable) ride with you to see what they think about the noise. If it's really LOUD, then something isn't right, but lesser amounts of noise can be signs of coming problems. You're probably OK, but if in doubt it's always best to have the car checked out by someone who knows their stuff.

Next time you have the oil changed, have them change the diff oil too. Make SURE they use the right stuff (there a number of good choices, but YOU decide what you want, and make sure that's what they use). It imght not quiet the diff down any, but it's not very expensive to do and certainly won't do any harm.

SpitfireS, Billman, or someone else might be able to recommend a diff oil that will (or might) reduce the whining, but I really don't know if such things even exist. As long as you follow Honda's recommendations you won't go too far wrong.

More info on my "whine". When I accelerate, it does not make the sound. However, it does under deceleration when the car is in gear and the clutch is not engaged. As soon as I lightly touch the clutch or the gas pedal, it goes away. I understand this (in my infinite reading of s2ki and what not), to be relatively normal, but gosh, mine sure seems loud. I sometimes find myself feathering the clutch or taking the car out of gear just so I dont have to hear that whine...

If CRC says their stuff is OK in the KAAZ then it's probably OK.
KAAZ may be able to give you greater insight into any tradeoffs that might be involved, so asking them too still isn't a bad idea.

LOL, I cannot tell a lie. The KAAZ also tempts me into misbehaving more often than I did before it was installed. I've owned cars with aggressive LSD setups before, and it's just too easy and too entertaining to lock up the diff and spin the tires a little when taking off and turning at the same time. I can't pull out of our local Kroger's parking lot without squeeling my tires a little. I think I could be fined about three hundred bucks if some cop wanted to be nasty about it, but it's so much fun I really don't care. I'm wasting tire rubber too, but it makes me smile, and I really can't help myself. No self control what so ever.

The KAAZ does more for me than just change the way the car responds to throttle inputs, and to me it's as much of a part of the fun as anything else. I could have bought a much cheaper car and modified it to have handling responses that were as quick or quicker than the S2000, for less money, but the S2000 also struck me as a wonderful platform for building my own E-Ticket ride. When someone new goes for their first ride, going through the rituals to avoid chatter and warm up the diff make the car seem (to them) more like some kind of crazy hard core racer. It is a part of the ride that helps prime them and pump them up more for what lies ahead. By the time we get over to the Huber road (private road, no cops or traffic) everything is well warmed but the KAAZ, so I'll do a couple 1-2 or 2-3 pulls, but I'll shift at 6k. Now keep in mind, with the CTSC/AC, I'm making as much or more torque at 4,500 RPM than a stock S2000 makes at 6,000 RPM, so the car is pulling harder than a stock car during the first 1,500 RPM of VTEC. This is quite enough to impress most people who aren't jaded, and it usually gets most first timers talking about how fast the car is. But (hahaha ) little do they know. I do a pull to 6k through the gears until we're approaching a second private road. I slow and downshift to second, then take the turn at 6k in second gear. The passenger never has the first clue what is about to happen ...
I get the car totally straight at a constant speed of 6k in second, and then SLAM the throttle open. Passenger is already thinking the car is quick, and the rush to redline in VTEC catches them totally off guard. Reactions vary from statemets like OMG, to giggles and squeeling. Some women swear that it's orgasmic.

Hahaha, I need to put a camera in the car to take pictures of the expressions people get on their face when they first feel the car leap forward as hard as it can.

Anyway, in addition to having fun with the way the KAAZ makes the car resond to throttle inputs, I also have fun with it becaue it makes the car seem a little more like a hard core race car to people, and it adds to the excitement and drama of their experience. All S2000's are about the driving experience, but I've tweaked mine into a thrilling experience for passengers too.

Maybe crazy, but having too much fun to worry about it.

Thanks Red.

Thanks Red! i drank 2 cups of tea while reading your explanations... very thorough, might be stealing this for a guide of LSDs or some sort for our local Honda club... Hope you don't mind, i'll put a
