Which LSD to buy, OS Giken,Wavetrac,Nismo or Cusco

3 posts in this topic

Posted · Report post

Just looking for feed back from anyone that fitted an aftermarket lsd in their Z. Since fitting MCA coilovers and Yokohama AD08R tyres it’s highlighted how weak the stock VLSD is . I don’t want a 2 way so would prefer a 1 way or 1.5 way . My car is a weekend warrior so don’t mind if I have to put up with a few clunks and pops from a nice tight diff . I’ve heard nothing but good things about os Giken and is my first choice but I’m also tempted by the Wavetrac. The Nismo GT pro kit offers great value for money but I’ve read it is very harsh in its operation. The Cusco RS also seems like a good choice although I’ve not read that much feedback about it. I’ll also put a 4.08 final drive in whilst I’m at it, just wish the Aussie dollar wasn’t so weak at the moment :-(

Hey Bry,

I too am doing some research on a 1.5 way for my Z as well. There are a few options out there however I don't think many Z owners have upgraded their stock VLSD. I've been chatting to a couple of guys in the US and they all tend to steer me towards the OS Gilken.

Not sure on the final drive though as I'd like to keep mine near 3.9, however the 4.08 would be suitable for an N/A setup.

p.s. I feel you on the Aussie dollar atm too... I have parts on hold in the US as it is and don't think I can hold out much longer.

Would be keen to see which route you take though. Keep us informed!

OS Giken does seem to be the weapon of choice. Interestingly I asked my local Nissan dealer for a quote on a Nismo 3.9 final drive gear set and it is a no longer available part, however, the 4.08 final drive gear set from a Nissan Titan is available for about a $1200 dollars which works out the same as importing from z1 motorsports in the states. I also started to get quotes for the seals and bearings in the diff and Nissan were hugely more expensive than everyone else I'd got quotes from. So the diff and the final drive plus the bushes are all available here in Oz at a reasonable price it's just the bearings and seals that will have to come from the states.

    • Best project car: Regular 370Z or NISMO?
      By Marsh · Posted
      Hi Ralph im also 45 YO. And own the very car you describe, For me it’s a road registered track only car and sometimes it gets taken out for the odd cruise (twice in a year). I bought a used 2014 Non Nismo 370z Manual and did the following mods, the intention was to always have this as a track toy.  Oil cooler Z1- This needs to be your first Mod  New Hardrace bushes and rear arms throughout the car. stillen exhaust front upper control arms (SPL)  good set of 2 piece disks and race pads- brakes are really good for about 6 -7 Hard laps  Then you have to back off for 1- I may get brake ducting, I see no need for an upgrade here. MCA Red coil overs - best Mod ever I can turn them down and they are very comfy.  white line front sway Bar  standard rear sway bar  Standard subframe and diff bushes ( I need to do the diff ones)  1 race seat 😀 1 professional race level alignment and corner balance  Nt01 semi slick 275 40 18 all round  car has a basic tune to enable left foot braking and maybe get it a little more responsive -uprev Nismo body kit for the looks - 😎 the car is absolutely on Rails And turn In is Porsche like. In the correct hands will Keep up with a hi end sports Car ( Not on the straights however, but Its not drag racing! )    Things I’d do to it now? 
      half cage (For my well-being)  Mechanical LSD As the VLSD doesn’t like getting hot and I have to change fluids every track day to keep it working. a few instructors have jumped in with me and they have been surprised on the cars composure and balance and those guys get to see a lot of cars. https://youtu.be/olkAcVSDwYs Im after something Lighter and more track only for my next car and am contemplating selling the Z but I would do so with a heavy heart, Maybe I can convince the Wife to keep it for her Daily....    All the best

      Hi, has anybody tried using Naviplus  to update the stock head unit? Looks like a tidy solution.

      Hey Ralph, Depending on what sort of power plant you left the clio in (in terms of mods and such) The nismo will be a far greater contender with the right mods attached. Depending on your overall budget for the car, off the top of my head. Everyones go-to mods are: Intake, hfc, cbe, tune, coilovers will set you a good 7k give or take on install costs. And given the right tuner you’ll see 240kw atrw. If you want to go turbo or supercharger. You’ll need deeper pockets unfortunately. Some turbo kits from the states are an easy 15k without clutch, flywheel and some without fuel pump and injectors. And obviously a tune on top. Then you add your coilovers and exhaust to that equation too. I’d personally set aside a potential 80k including cost of the car if you were looking for a daily driven track car. And i wouldn’t really expect a great return on investment at the end of the 4 years regardless of the mods. Sent from my iPhone using Tapatalk

      Hello, one and all! It's nice to be posting on this forum for the first time. I'll introduce myself, and then get to the reason I've joined this forum. I am a 45 year old man with a love of old-school performance cars. I've owned numerous Honda Type Rs and an S2000, as well as a couple of Renault Clio RS models. I like cars that handle like go-karts, rev like crazy, and are as close as possible to analogue motoring. My job requires me to have a new car every four years, and I am looking to trade-in my four year old Renault Clio RS Sport for the kind of car that is almost extinct: a manual, rear wheel drive coupe; just because I still can. I do a lot of country driving, and I take my cars to the track, so I want a car that will be a proper and entertaining machine at the limit. I have looked at the current options for a new RWD, manual coupe, and there aren't many that come in under $100,000. In fact, the only cars still being made that aren't tanks from America are the Toyota 86/Subaru BRZ and the Nissan 370Z. The BMW M2 is $110,00 plus, and then we come to Porsche Cayman and Lotus Evora ($150,000 to $200,000+). So, I am looking to spend no more than $60,000 on a Nissan 370Z, and add some serious coilovers, brakes, exhaust and tuning to the package so as to turn it into an M2-beater. My questions are these: 1. What are the differences between the regular 370Z and the NISMO, and could those differences be improved upon if I bought a regular 370Z and got it properly suspended and tuned? 2. How does the 370Z respond to suspension upgrades? I want a car that I can throw into corners, and be confident it will stick. I'm used to Honda Type R and RenaultSport models that turn in as if they're on rails. Does the 370Z chassis respond well to coilovers and camber change? I'm looking at KW Clubsport or something similar. 3. What is the best option for tuning the 3.7 litre V6? Can much be gained from lightened flywheel, upgraded exhaust, remapped ECU, cams, etc., or is supercharging or turboing the best way to liberate the engine? I like a free-revving engine, and I've read the 3.7 litre V6 is quite lazy. If so, can this be significantly improved upon? Okay, I'll leave it there for now. Any advice would be much appreciated. Cheers, everyone. Ralph
