I hit the search button,

Whatever you use, make sure you've got a GL4 oil for your gearbox and a GL5 for the diff. Personally I like Redline MT90 as it stands up to a lot of track days, but can be a bit thick in Winter. MTL is good for street-use. Didn't rate the Nulon stuff and currently running Castrol Syntrans, which isn't too bad but I haven't been using it for very long.

I have a 1.5-way diff so I use Motul competition oil, 75w130 weight or something.

I have change my Manual box oil recently. You can try Motul Gear 300. It can be used for both box. I was recommended Royal Purple for my gearbox, by this autobarn guy, as they ran out of Motul. I can say not totally happy with the purple. It's works ok after a few km during early morning cold start, but during the 1st set of traffic lights I pull up. Always have difficulty put it into 1st gear, sometimes 2nd gear too. After the oil has warm up, then It do feels very smooth. I have yet to change my Diff oil, so I guess you can try some other and we'll see how. The purple does seems to be much thicker than the old oil I took out. Quite a lot of metal filing can be seen from my old oil, but maybe the oil got so old that it has thin out. It's recommended by nissan to putting 75W-80 for gearbox and 80W-90 for Diff. The Royal Purple and Motul are both 75W-90.

Thanks for the fast reply guys,

i changed the motor oil as soon as i got the car few weeks ago but never even thought of doing diff and trans till i spoke with a fellow SAUer last friday. I drive maybe 10kms per day if that, pretty clean run with barely any stop/start but id rather be safe then sorry :)

Now regardless if your a Nulon fan or not,

this is a good guide to use: http://www.datateck.com.au/lube/NulonAus/default.asp

Just specify car, nissan, then i went for 350z and it lists in categories ie motor, trans etc which oil you should use.

      R34 gtt rb25det neo timing belt kit

      By drifter17a · Posted

      So now doing the change and first time dealing with rb so little nervous giving engine power and potential for screwing it up When you align all marks and then remove crank bolt, timing move little I assume you can put the bolt back in once you have removed the pully to get timing to where you want?   here is pic of my both intake and exchust cam aligned, depending on angle you look they seem to be either aligned or a half tooth or so out. Any thoughts? Should you angle your face and look at each mark that way as if looking straight rather than from above as it can be misleading   <a href="https://ibb.co/ZpnhcvbF"><img src="https://i.ibb.co/HfWrGR9b/IMG-4447.jpg" alt="IMG-4447" border="0"></a> <a href="https://ibb.co/4wm2wn4q"><img src="https://i.ibb.co/JWBqWwr1/IMG-4445.jpg" alt="IMG-4445" border="0"></a>   https://ibb.co/ZpnhcvbF https://ibb.co/4wm2wn4q

      braided lines for the turbos

      By sunsetR33 · Posted

      Thanks for the reply @GTSBoy Haven't really thought of that yet, but you are right. If the hose was damaged it should be absolutely pissing by now. I'll put some heat sleeve around it for good measure since I'm already removing the line anyway.  Maybe I'll put on some of the stock hardlines if I ever fully remove the turbos again. Maybe when T51R modding the compressor housings? Might be a fun mod on GT28s for that "fake single turbo" effect.

      Unpeeling the Orange

      Update 1: I did some work on the car already before finalizing this post and my "issues" list. I dropped the Tomei exhaust in favor of the HKS Hi Power Silent. Sounds nice and I can actually hear myself think now. Also gives me a realistic chance to legally drive without silencer inserts. A bit of cheating was necessary to still be able to mount the Top Secret style diffuser. Some malusage of washers and a bit of "convincing" toward the brackets and exhaust hanger seemed to do the trick. The shaky steering wheel has been resolved as various suspension components were worn, like sway bar bushings and link bars. Most notably the two steering tie rod ends. Had some trouble finding bushings because my sway bars are not OEM thickness, 23.x up front and 27 rear. But non adjustable, so no aftermarket I suppose. Maybe they are nismo units? Turbo oil drain hoses were definitely still the originals and are new now. Wasn't the cause of the turbo oil leak sadly. Currently removing the rear turbo because of it, I suspect the braided oil feed line is the culprit. This issue needs to be dealt with so I can work towards actually getting the turbo setup legal and inspected. Two new issues to add to the list as well. Rear Main seal is probably leaking. Time will show how bad it is, I don't really want to drop the gearbox right now just for the stupid seal. Could fix a few other things in one go once I do that. Front right driveshaft grease is going past the cv boot, so at some point I'll fix that too.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Ok so no 4cyl clutch... Yeah it is a factory manual. So if iam correct i need clutch and flywheel too? I can use something that suits something like R32 GTST?   EDIT: https://www.ebay.com/itm/224291042776 Is this ok?   EDIT2: i maybe forget to mention this(dk how important it is) but the trans will be behind RB25DET NEO(iam doing swap) It will be there for a little while. Iam planing to do bigbox or BMW tranny..

      You're probably right about that one. Thanks for your suggestions, I hope I don't need a new 3rd brake light. Although wiring issues might arguably be worse. Right now I'm in the midst of a turbo removal because of my oil leak, other problems are going to have to wait for now.
