drive very conservatively until you can use 98. If you have E85 around, squeeze some of that into the tank and dilute the 95. Around 10-15 litres will help, octane booster will also work if you get one that actually works.

on a NA 95 octane should be fine. any misfires on 95 won't be from the octane rating. might be from the quality of fuel, but not the octane. you could also try backing the timing off a bit if you are worried.

japan's octane ratings are the same as ours, they just happen to have one that is even higher, but they still have 91 and 95 octane fuels over there from what i gather.

Geeze u guys do like if 95 is kerosene or some shit....

Where i'm from 95 premium is our best brew and we run all skylines on that with no probs...just keeping the boost down on hot days

i run e10 95 in the stagea and keep the boost to 5psi most the time and it runs fine

even on 7 psi its ok, down a bit of power compared to 98 but its fine

Yes, but the average altitude of Japan is about 1000m, whereas our average altitude is about 400m.

I believe the "knock" map on the standard ECU is designed for 95 octane.

Yes, but the average altitude of Japan is about 1000m, whereas our average altitude is about 400m.

What's the relevance of that on a MAFed engine?

i forgot to tell you guys that my spark plugs was the cause haha. running on 5 cylinders was fun.. NOT

95 is fine stuff but i still run 98 nowadays

Not trying to be rude, but a car down a cylinder sounds a lot worse than the odd backfire... How did you not notice?

    • I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp
    • Forgot to mention that these are the before pics when I first got it!
    • Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆
    • Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
