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.

    • Hi again all, I’ve tried doing some searching on the topic but couldn’t find the answer I’m looking for.   I deleted my clutch booster because it had an air leak and was squealing like a hog, and now my clutch has very poor pedal feel and the friction zone is way too small, so I believe I need a bigger diameter clutch master cylinder to compensate for not using the booster. I found a Wilwood option that’s 3/4” for a good price and will fit my 3AN clutch line, but all the firewall adapters I see online such as RB factory or Chase Bays are listed as RWD only (GTST/GTS). Link below. https://rbfactory.shop/products/nissan-to-wilwood-girling-clutch-master-cylinder-adapter My question is if these adapters will also fit a GTR, and if anyone has experience using a 3/4” CMC without the booster, my clutch is a Nismo coppermix twin plate.   Thanks, always appreciate the advice!
    • Catching up on a post, I've replaced the external shark fin with a small 4g antenna (no further drilling, just a 1mm embiggening of the existing hole, and run that to where the dual battery models have the battery in the left rear guard.  No idea what the factory antenna did, but removing it had no impact on anything I use, according to the US manual the GPS antenna is in the dash and it still works fine Also ended up stealing battery power from one of the amps and ACC power from a unit nearby to add an ACC relay to power it. The mounted the booster, wifi, power socket and antenna splitter in the rear left guard out of the way, all out of site with the boot trims in
    • What drama? The only drama you're going to have is the near constant work to maintain all those sphericals. I only have sphericals in my front caster rods and front upper CAs (because both of these are near compulsory in an R32). I have had the front arms out of my car 34 times already this month, and if the new replacements arrive today, I will have them out and apart again tomorrow. Chasing clicking and clunking that comes from sphericals being a.....poor choice for a road car. Moisture and dirt are not their friends. I have been contemplating a change to my rear subframe that would require me to use sphericals in my lower CAs. And.....I don't want to have them that close to the road.
    • Did you need anything else you've already done? If you had it before... and liked the changes after, then supposedly it'd be more of the same. The idea about most suspension arms is to tune geometry that the OEM arms max out at/can't handle because they weren't designed to have the car setup in such a way that 'looks good'.
    • I have replaced everything on my r34 including suspension to Miester R, all rear subframe bushes to poly, all arms to metal adjustable and same in front.   only thing I haven't touched is the front lower control arm. Should I? what improvement can i expect ? I mean the one on the link below?   Car drives perfectly, it is just me thinking everything is either puly bush or hard bearing type so should also do lower control arm front but do I really need it ? https://www.japspeed.co.uk/product/suspension/adjustable-arms/nissan-200sx-s13-s14-s15-skyline-r32-r33-r34-adjustable-suspension-front-lower-control-arms/?gad_source=1&gclid=Cj0KCQiAo5u6BhDJARIsAAVoDWs5V_PauQPf0kx3zFCaA4tOC9Q7JSIsfJWma_jAPN2f1sJA686djOwaAidgEALw_wcB
