You actually couldn't be more wrong.

Longnose R200 in a HR31 is a 2-way mech locker, just very loose.

Few places and shims later, it's exactly the same as the Nismo item, or better if you customise it up a bit.

WTF... Are you reading the same post mate? or even the next line after the one you have quoted above?

"Viscous LSDs are not the real deal and even when new do not provide the response or locking capabilities of a mechanical LSD, after 100k+km's and a few laps of Sandown the stocker is 100% useless!"

No doubt the R31 diff is a doozy... but the R33 viscous LSD is a POS!

2 way - locked under deaccell

1.5 way - partially locked under deaccel

So 2-way & having the rear wheels turn equally going into a corner with it locked up generally will induce understeer.

Once you get over that, it will snap/insta oversteer

How do you deal with the tendency to plow on in corner entry then - I'm referring to driving style - you just got to chuck it about more?

If you aren't drifting etc, IMO 1.5

2 way is fun if you know how to use em, but very demanding.

So you're saying that?

1.5 way = ghey

2.0 way = Charles Bronson?

:rofl2:

Ok so i know sweet F A about diffs and dont profess to but my car has a kaaz 2 way and its rough as guts at low speed cornering on nice smooth concrete it chirps turning & the whole car shudders it is quite unfriendly for a daily drive. I personally havent noticed any difference in how it affects the handling though i must admit in the wet it does feel seriously slippery but i boiled that down to lotsa hp lol! BUT with 386hp on the tar my car doesnt do a great deal of wheel spinning

Never get why ppl complain about 2ways shimmed welded diffs for street i drove on weldy with 300 kw on the street for over a year and no problem if you drive properly its fine besides being abit noiser theres not much difference for everyday.

The Kaaz LSDs are noisey as fark during low speed cornering and put alot of stress on the rear subframe etc.

Some guys claim to quieten them down with LSD friction modifier but that only detracts from the performance of the LSD and is IMO ghey...

Kaaz LSDs are "off road" products designed for racing not daily driving it's as simple as that.

After I did mine I also replaced the diff mounting bushes and installed alloy lock collars on the rear subframe instead of poly pineapples - a vast improvement in rear end shuddering, axle tramp and subframe movement!

I can assure you that if you went back to a standard diff you would notice the difference - bigtime with 386HP!

My Kaaz LSD improved my lap times by over 1 sec @ Sandown simply because I could get more power to the ground earlier on corner exit and therefore reach higher speeds on the straight etc. It is also much easier to control the car in a power over-steer (i.e. drift) situations and in general.

The best thing you can do for a KAAZ is to run an 85w140 or similar LS oil. The 80w90 that they come with is just a run in oil and way too thin, creates heaps of noise when the oil warms up a bit.

Also, when going around corners at low speed (daily driving etc.), you can either hold the clutch in so it just coasts around the corner silently, or with clutch out give it plenty of throttle so that the tyres start chirping instead of the diff chattering. It's slipping the clutch around a low speed corner that causes the most chatter because you are power on / power off.

Is it the A-LSD that you are referring to ?

still running one with a lot of track work and 600+rwhp fine ?

I dunno dude... Do you see the letters "A-LSD" anywhere in any of my posts???

You can probably work out the answer for yourself from here... :blink:

P.S. You should be up for TROLL of the year with this! Nice work!

both me and a mate have OS giken 2 ways in our cars...

his.. unknown how long its been in, or when the oil was last changed..

i ordered my diff from otomoto in sydney, had to be shipped out from japan,

i am using the genuine oil... 80/250w grade oil , seriously thick!!

my mates one... chatters and makes noise like crazy.. mine is still quiet!

it has started to get a bit noiser now, but that could also be put down to the fact i just added solid metal subframe bushes and diff bushes.

getting use to the diff is easy... first time i drove it after fitting it ,was at a track day at wakefield.. just had to adjust the way i drive.. on the street i dont notice any real difference, coming out of round abouts is a bit more fun under acceleration as it feels alot better.

each to their own..

      By GTSBoy · Posted

      You've done it wrong. I don't have time right now to type up enough. I'll have to come back to it or maybe someone else will in the meantime. The boost signal has to pass through the MAC valve from boost source (turbo outlet - effectively anywhere between the turbo outlet and the throttle body will do, but closer to the turbo outlet is best) to the wastegate. What you have done is connected it sort of like the stock solenoid. But it doesn't work the same way as the stock solenoid. That Tee piece that you have connected the solenoid to....? The solenoid itself serves that function. You should look up a typical MAC valve connection diagram for a single turbo internal wastegate application. You'll find one easily enough. Every single boost controller manufacturer that uses MAC valves will have one. Bugger it, I'll just grab the HP Academy one. The other thing you have to get right is that the boost source has to be connected to the correct port on the solenoid valve. This is because the solenoid makes the valve switch from connecting 2 of the ports when it is unpowered, to connecting one of those first 2 ports to the third port when it is powered. One inlet, two outlets. You will note from the diagram that the common port is port 3, the port to the wastegate is port 2, and port 1 is the vent (where the boost signal escapes when the solenoid pulses ON). As to the BOV.... the vacuum signal for the BOV simply has to come from the plenum. It must register boost when you're on boost and vacuum when the throttle is closed. That's all. The original location on the plenum is best. Best practice is never to interfere with the vacuum line running to the FPR. Just leave that one alone, as you will avoid causing unintended problems that might occur if you mess something up.

      I was able to complete installation of the G4X ecu. I needed to reroute MAP vacuum signal from stock location to where BOV is connected on the intake plenum. Has anyone needed to do the same? When I connect vac port by the BOV flange to my HKS BOV, it doesnt work and I get flutter. I would to get BOV working, where would it be best to T in? Or would it best for me to move MAP vac line and T into FPR? Secondly, I installed a MAC 3 port boost solenoid and wanted to know if i routed it correctly. I place two lines from stock boost solenoid and placed it on ports 1 and 2, leaving 3 vented. The T for wastegate and boost source on compressor elbow is on port 2, and port 1 is connected to turbo inlet intake pipe. Please see attached pictures. Ill upload ecu config later today. Thanks in advance.

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      So I raised the car up a fair bit for shipping - see image - then lowered it again when it arrived. I then rushed to get an alignment in NL before the track and the shop just wasn’t anywhere near as precise as what I got in Japan. The guys that did the alignment this week said there was a fair amount of toe in the rear that could have contributed to the understeer. It was also the case that the rear camber went from about -2 to -3 at the shop in NL. However, since I’ve now got slightly wider tires in the rear - NS2Rs run wider than Accelera 651S - I could only get a minimum of -3 in the rear now due to clearance. Front is now -2.75 (-2.45 in minutes) due to being raised a bit (previously -3 in JP). So it’s likely a combination of the two factors, camber and toe. The issue now is I have more camber in the rear than the front and the next step on the front Cusco arms will put me at -3.5ish front which seems a bit excessive to me. The weird thing is I’ve never had any understeer at the track in Japan but they are very different circuits - Japanese circuits are much slower than the one I’ve been to here.    I’m probably going to have to start another thread for the E90. The plan is sort of to keep it as a daily but progressively mod it into a track car - honestly, you need a cage for the sort of speeds you go here. Just ordered the M3 front arms btw.  Love the car despite it being in pretty shitty condition. Oil analysis came back okay and it seems to have stopped consuming oil since fixing a load of engine bay things. Saw yours is a 335i right? f**king mistake on my part getting the DI N53 over the N52, fuel economy is insanely good though at 14-16 km/L.   Cheers, it’s great to see the benefits and pitfalls of different places. I’m contemplating going back to the U.K. around next year as the cost of living in the Netherlands is just ridiculous. GF is nagging me to settle and buy a house but I don’t know what LSD to buy.
