Hi guys, been looking about and don't know if I missed a post but can't seem to find the recommended oil for an RS Four S manual. Does it make a lot of difference? The diff oil seems to be 75w140 is the gearbox oil the same viscosity or more like 75w90? Could also use info on power steering fluid and 4 wheel steer fluid, is it all some kind of generic steering fluid like dot4 for brakes or is it some special blend that only Nssan and a couple of other places make? I have a trade card for a national parts place so generic PSF is cheap in 5l bottles lol

Cheers for any info guys :)

p/s and attessa (the one in the boot, RHS) take normal power steering fluid (idealy nissan matic-j but i think the one below is ok too)

not sure on gearbox oil but check what an r33 gtr would use, they should be in the valvoline/castrol/etc books

Hi Dude,

For the Attessa reservior in the boot, power steering AND transfer case on the box - use a high quality dexron III auto trans fluid, castrol trans max z is what all of us are using when $$$ isnt a problem

As for the gear box depends on its condition to help syncro life I'd recommend Leightweight shock proof...

Hey Bud,

As above peeps have said already.... Dextron III (or equivalent) for Attessa, P/Stear and Transfer case.

I use Redline in my Gearbox as well as Front and Rear Diffs. Using it in the Rear Diff can make the LSD lock up a smig earlier, but its no problem as long as you don't mind (It still acts like normal). And thats the whole point of having a LSD anyway.

Not sure if you wanted it also, but I run 10-30W (I think it is) Royal Purple in the engine. I honestly swear by this by the way. I've used a few diff oils and this stuff is amazing.

Anyway hope thats what you were looking for :)

If you are going to use Redline shockproof in your gearbox use only the lightweight version. If you have a viscous diff 75W 140 but if you have a mechanical lsd you must use a special lsd oil such as motul 75W 140 for lsd.

Thanks for the info guys, I was looking at special LSD oil and the same version but for the box, both at 75w140 but both state not to swap them, as for the psf and atessa I'll have a scout for some good stuff like the castrol and see what I can find. The box and diff oils I'm going for are specifically made for the job and motorsport use, the box oil actually stopped a high power evo from chewing up the synchro's. I believe having the rs four s the stock lsd needs the special lsd oils?

Engine wise I use 10w40 royal purple, have also used fuchs silkolene but the purple is like nothing else oil wise, no idea what it's exact chemistry is but it works a treat, keeps the engine quiet and helps the turbo spool up.

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
