Hi.

I plan to import a Stock Nissan Skyline R33 RB25DET. Octane 98 is not available in my area. Would it be ok to use Octane 95 after I reset the stock ECU? Is the stock ECU hard map to using only Octane 100? Or, since I can not get Octane 98, I should import a Nissan Skyline R33 RB25DE instead of the turbo? I do not plan to race or modify the car. Also, what is the difference between ping and knocking? On my old car, my knock sensor was not working properly, so the dealer diagnosis it because the check engine light was on, so I had it replaced.

Knocking and pining are the same thing, differently worded. I beleive tuning the car would allow it to run on lower octane fuel, but you'd want to be even more sure that the air temps are cool especially on hotter days.

If you are going to mod, and run more boost, the summer air could cause some pinging if you don't run an appropriate intercooler.

That's my input, but i'm sure that more veteran-style users will give you better info. =-]

You could always run octane booster but that could get a tad expensive puting a bottle in every time u fill up.. lol

95 should be ok aslong as u run stock boost and get the car tuned correctly.. because fuel quality always differs..

I run 95ron full time as its the highest available here. I'd say fuel up with 95, reset the ecu & u should be fine. Stock ecu is not tunable... but, its clever enough to retard the timing if it detects detonation.

don't be ignorant people...

your options are:

1) don't get a car if you can't maintain it

2) if you MUST have it, then either get the timing retarded or the ECU re-written to accomodate the different fuel

i ask you this question... would you put deasil in, if it were the only fuel available in your area?

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
