What is different about it other than the RON?? If it is just a higher octane fuel, it is a complete waste of time. Nissan specify 96RON fuel, using anything higher is of no benefit in a stock engine/tune. If it costs more, it is flushing money down the drain.

Burns hotter. So it's cleaner. If your car is tuned for it you'll get more power.

Better economy.

If your worried best to ask Nissan. Say to them you have a 350Z. ;-)

have you seen the price of that fuel? Its certainly not economical.

Tuning for it is completely stupid.

Ya i took it into my mechanic, he isnt really sure what it could be. His thoughts were either a missfiring spark plug or pinging. He said he wouldn't know until he started changing parts

Go somewhere else. A misfiring cylinder doesn't sound like pinging. ...

VQ's rarely ping, the knock sensor is pretty good at picking up knock and dropping timing out. Are you sure it isn't just a bad batch of fuel in the tank?

If it is indeed pinging, I would be looking at fuel supply. Have you changed the fuel filter at all?

Does the noise sound like nails dropping on a tin roof?

The noise been happening for a while. It only happens in certain revs, at the star it would happen between 1.7 - 2.2 but now also does it between 2.8-3.2. It sounds like a metal on metal sound, i guess it kinda sounds like nails on a tin roof. I always use bp ultimate but once last year used 95 for some reason. I dont think the fuel filter has been changed...

Check your heat shields aren't coming loose. I've had a light metal rattling sound since shortly after I got my Stagea, always around 2000-2500rpm on light/medium throttle. I came to the conclusion a long time ago it was most likely a heat shield rattling due to engine harmonics. I'm just super-lazy and haven't bothered crawling under it and prodding things around.

Another possibility: I don't know if the V35s are constructed the same as the Stageas but mine has a twin-walled exhaust, with the outer layer having corroded through, meaning lots of thin, small strips of metal to tap against the inner wall. Any day now I'm hoping the inner wall will rust through and I'll be forced to fit something better.

Performance hasn't dropped off at all, it burns almost no oil between changes (5,000km) and the noise is always under the same conditions.

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.

      To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all

      300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
