MY Kaaz sounds like its tearing itself to pieces!

Its was making BAd noises from the begining, as soon as i reversed out of the shed and turned it was doing it... i had to drive around 15k to get to a car park to run it in, but i drove sensibly...

when u go round a corner with the clutch in it makes a bit of a whiring noise.. that i expect.. but as soon as u are driving normally it doesnt sound happy at all....

(sounds like the thing is skipping splines on the axel... and no its not.. i checked.. twice)

if you have put redline diff oil in then this could be your problem, the oil is too thin for the kaaz diff and results it becoming very noisy; when did it start making the noises?

Ive got a kaaz 1.5 way with about 1500kms on it, and im not happy with the clunks and grinding noises either. Im thinking of pulling it out and putting a standard one back in. I changed the oil after run in with more kaaz oil, and the diff became a bit quieter, but still feels as though the rear cradle is dragging on the road when in car parks. I f**kin hate it at the moment.

I changed the oil in mine yesterday and put some Penrite Competition diff oil 140w in it and it is ten times better! still makes afew noises but nothing like it was!

So did you have the recommended Kaaz oil in it before you changed to the Penrite?

Ive heard that the Penrite seems to quieten them down a bit. When you say "a few noises", do you mean clunk!, clunk! around tight corners in car parks, or just slight grinding noises.

Thanks,

Shaun.

Toughen up people!

If you wanted a quiet diff you should have stuck with a viscous LSD.

I have changed the oil in my KAAZ diff twice, both times using KAAZ oil, each time it has quietened down a little. I am due for a third and final oil change, which will be done shortly, using a Castrol oil, which has been recommended by a friend using the same diff.

All mechanical diffs will be noisy as you accelerate gently through a corner, if you don't like the feel/noise just push the clutch to eliminate the drive force to the diff. I just don't worry about it.

Mate it doesnt worry me a f**k if it makes a few noises.. but this wasnt right at all.. it made more noises than a auto locker... now with the new oil its spot on!

I wouldnt recomend the castrol oil, ive got a nizmo 2 way and had the castrol stuff in there, wasnt to bad but later on i changed to penrite 90 weight stuff and it it heaps smoother, still clunks and stuff but i dont mind that :P

might be different to the kaaz ones, seems like you guys are all using a much heavier oil

2way LSDs are very aggressive and thanks to that will always make a noise and theres almost no way of drowning the sound completely but at least when your cornering you tend to forget about the noise. tho, i gotta admit the noise is annoying.

from what i heard from some, the nismo 2 way and the tomei technical trax 2way are quieter than the rest.

these diffs are supposed to make noise it feels like the whole cradle is moving and ready to drop out but if you don't want the noise then get a stock car i'm pretty sure all of these things ultimately have the race track in mind and that's where they are supposed to be used hence the lack of quietness if ya don't like it stock is the way to go mine sounds like crap but if ya want it you put up with it still works a treat oh and i use motul oil essentially the same as nismo oil just without the nismo and price tag

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
