I'm one of the owners who is getting my car maintained by a non NHPC garage but am using genuine fluids in order to maintain my warranty. It's time to do my diffs and I can either buy the factory specified SAF-XJ 75W-140 for $60 for 500 ml from the local BMW/AMG dealership or else purchase 20 litres for $567 from Supercheap Auto. They don't sell it in smaller quantities. Trouble is 20 litres will last me around 270,000 kms based on the standard service intervals of 30K and 2.2 litres for both diffs so if anyone local wants 10 of my 20 litres I'll be happy to sell it on to you at what I paid for it.

Just out of interest, Nulon specify their 80W140 gear fluid for the GTR and appear to be happy to provide a warranty in case Nissan fails to honour the warranty as a result of them blaming the Nulon for the failure. Interestingly the Nulon says it's a 100% synthetic but I have been told that it's really a highly refined mineral oil. I'm no chemist so don't quite understand the ins and outs of how they can claim that its synthetic when it isn't. Either way I'd rather just go for the recommended stuff than stuff around with that whole blame game process if something was to go wrong with the diffs.

nulon have a habit of claiming their fluids are full synth when they're just a GrpIII oil - their argument would be that it's "close enough" to a full synth.

i'd stay clear of Nulon, especially for a R35

Yes but at the expense of this:

" When using this oil, LSD efficiency will be greatly increased (with especially good high-speed performance), but there will also be greater wear on the LSD's internal clutch plates. Please be aware of this before purchase."

and this:

  • This oil was developed for high-intensity competition driving. Please note the following two points before using this oil:
  • 1. Except in the case of the Nissan GT-R (R35), this product is not covered by Nissan Motor Co., Ltd. warrantees.
  • 2. When this oil is used, it should be changed every 3,000 kilometers.

So pretty much track use only? And has Nissan confirmed these warranty claims?

      Before you blow your car up, have you checked you've made all the correct modifications to the wiring if you're still using the RB20DE loom?   Some things to look at: The pin used for the map sensor on the RB25DET, is the same pin used on the RB20DE for the Ring Gear Crankshaft Position Sensor, no idea what you've got it plugged into now. The turbo pressure control valve solenoid you're talking about on the RB25DET, the same pin is used for the Variable Air Intake Control Valve on the RB20DE.   The factory manual has the wiring pinouts in it for you to check everything. It also has the diagnostics process to read codes out. In addition, there's a great table that shows what sensors and what actuators not functioning will relate to which signals. And Nissan confirm the as everyone else has from experience, the Solenoid being disconnected won't cause a fuel cut. However, the turbo pressure sensor being missing / wrong, WILL cause a fuel cut. https://www.nicoclub.com/service-manual?fsm=Skyline%2FR34-Workshop-Manual-English.pdf

      I've been hunting info on the G Series II - this is best I have found so far(Link below). Still waiting on the G35-1150 comp map, kind of very keen   So how do we go about getting precision on that little table of yours ?   https://turbosbytm.com/sites/default/files/product/technical-info/Garrett-G-Series-II-Product_Flyer 25 30 35_1.pdf

      yeah I get ~0.6L per session into the catch can. very ethanoly. It ends up overflowing out the breather of the catch can on circuit days too even with a 2.3L capacity catch can and I only drain out ~0.6L max. So every session I have to come in and drain the catch can, which is a hassle. So this is me cracking the shits and doing everything I can without removing the motor (back of head sump drain/breather and oil restrictors off the table). plans short term are: full length splash plates remove oem cam cover baffle add foam and reinstall at -10 or -12 AN fittings to the side of the cam covers down to the sump (luckily I already have fittings in the sump) Yes the ~340,000km unopened motor is probably not helping things

      I'd use any fuel safe foam....mine went in 15 years and 15 rebuilds ago, still getting reused I'd have to say I don't understand swapping to studs to fit a particular baffle unless you are having a massive blowby issue, and even if you are addressing crankcase not head breathing is probably the next step.

      BTW, the reason I came in here to "update" this list was that the Garrett G Series II range have been released and I've updated the list with their flow details if you're curious to check how they fit with previous Garretts and other brands The G-Series II G35 990 looks like a banger...
