I think what he's trying to say is that he doesn't see the need to run 100RON fuel in an N/A car... Obviously there's N/A Hi-po cars, so if they're after a bit of a safety buffer from knock etc then I'm sure they'd run higher octane fuel....but your everyday N/A car doesn't need 100RON and isn't going to gain anything from it...

yeah of course you wont gain anything, even an turbocharged car gains zero without retuning

but he is wording it as though your fuel lines well melt if you put 100ron with ethanol in an N/A car

my car has been tuned for 100 v-racing (it was a good power gain, just ask racepace) so i been running it for 2 years daily driver...

the car has not missed a beat.

in all honesty I fail to see how its going to rust out the fuel lines.. Unless the car is sitting unstarted for months, But realistically the amount of ethanol present isnt that high at least not in V power racing.. That E85 fuel I would be more concerned about

Ethanol doesn't rust out the fuel lines... ...I'm pretty sure that "opinion" came from people using Bio-Diesel containing Ethanol as the "active" ingredient, where it was cleaner than normal Diesel and would clean out the fuel systems... ...Which meant you'd have to keep changing the fuel filter until the fuel system was clean and the injectors would sometimes clog...

Ethanol can eat through the materials that are used for gaskets... ...Ie. paper, rubber, silicone, cork, felt, neoprene, nitrile rubber, fiberglass, or a plastic polymer...

Just like rubbing alcohol can eat away at the surface of a CD... ...Ethanol eats away at the gaskets depending on what they are made of...

And while ethanol won't do much to most metals... ...I think (I was never good at high school Chem) ethanol can eat away at iron... ...but it isn't technicality "rust" as such because I don't think it is classed as oxidation because most alloys that engine parts are made of are resistant to oxidation... ...the ethanol is just picking on the iron parts...

I hope that kinda makes sense... ...I haven't studied in about 10 years... ...So I could be totally wrong and talking out of my ass...

yeah of course you wont gain anything, even an turbocharged car gains zero without retuning

but he is wording it as though your fuel lines well melt if you put 100ron with ethanol in an N/A car

well my wording must be a bit misleading, sorry. The point im trying to get through is what dez stated.

You will gain nothing from running that fuel in a NA.

I just went on the United website and they are bringing out a new fuel, Premium 100.

I think I will try this out when its avalible, depending on price.

I have recently changed from BP Ultimate to Shell V Power Racing and it is definitely a superior fuel. Where as my car used to sometimes get knock up around 6,000rpm now I don't get any knock. It also makes the car feel more responsive.

It's good to see that United is bringing out a 100 RON fuel as I didn't want to have to go back to BP Ultimate!

Just thought I would let you all know Ashburton Shell sell V Power Racing for 1.69 a liter and the price hasn't changed at all over the past 3 weeks. Hence when ever its high price time the extra coin for V Power Racing is only about 9.5-15c a liter over regular fuel. What a bargain! I went to a Shell on Burwood Hwy and V Power Racing was like $1.85 a liter

  • 3 months later...

you can put standard unleaded in an n/a and turbo skyline (Gts, GTST, heck even a GTR if you like)

in all cases the car will run, start and drive fine

once you load it up, it will detonate, the ecu will see this via the knock sensors and it will run a low octane timing map

so the car will be sluggish and perform like poo basically

    • 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.  
    • 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       
    • 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).
