I have had this short 'grinding' noise intermittently for several months. Low speed, first gear, once or twice low speed second maybe?

I have only used LC2 a couple of times (no not understating to protect myself)

Anyone else had this here?

Taking car to Nissan prior to next track day.

lol whats FWIW stand for, i cant work it out.

Just sounds like that its a pretty rare issue at this point in time, probably one of those things that happens to every car model, there are so many things that can go wrong that its amazing that the r35 has such few things that are actually failing on them, thje more parts and gizmos in a car, the more chance that something can go wrong.

Don't worry about it untill it happens to your car or you will always be paranoid looking for something to break

the GR6 transmitions not very smooth at low speeds but several R35s already have transmition problems like while they are still new and not even driven hard. have your tranny checked, hopefully its just the normal operation. we do have customers coming in complainin about some rattly or grinding noise before as well.

this occured with oem fluid long before the pentosin went in. havent had it since (you can work it out by dating this topics post date and the pentosin post date).

The transmission is actually a bit quieter and smoother with the pentosin in for what thats worth.

proof will be in how it holds up to the 10,000 road km use and 1,200 track km per year over the next year or so if the tanny lasts that long.

the car is a 2009 model.

I have had a slightly different noise when changing from first to second. There is a bit of a clunk noise from the gear box. It is not a gear clunck, it it more like a sound of metal hitting metal for a split second. I hear it more when travelling through tunnels or when the sound bounces of surrounding buildings, it is more pronounced under hard acceleration.

I havent had any grinding noises but FWIW whilst there is no doubt the Willal oil is the best track solution, and still beautifully smooth on the shift, my car (tranny) shudders like a bucking bronco off the line in daily driving. I'm thinking about going back to Nissan oil for a while to see the difference...

that sounds like gearbox/engine mounts to me which makes no sense as they usually take a while to give up

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
