Hey guys,

I have searched for topics about this, but have been unsuccessful so far. It is s bit of a noob question, but I thought I would get different peoples opinions.

I have a r32 GTR due to arrive next week from Japan etc running the stock ecu. I am a little lost on the whole fuel thing , and was wondering what my optionsr for different fuels are....

I understand the difference in octane in japanese fuels and fuel here in aus, however is it as simple as;

1. Use 98 with octance booster, or

2. Upgrade ecu and tune for lower octane fuel,

I guess I am looking for peep's experience with different fuel and how they have solved this issue.

Nulon makes 2 grades of Octane Booster.

Once I detected pinging immediately after filling it with 98, I started using the stronger version of the above - trying to boost the octane up to perhaps 104 in the tank. I kept this up until replacing the Mine's ECU.

Result:- Whilst pinging reduced somewhat, but not completely, 8 tankfuls later when I switched to a PFC D-Jetro, the plugs were just about etched to death.

Moral:- I wouldn't use the octane booster for more than about 3 fill ups - in the interim, getting that new ECU if the existing one can't be remapped.

When the GTR was released in Australia the highest octane petrol you could buy was 95 octane. They ran happily on that. True story.

So you can actually run a stock GTR on 95 octane. Most people use 98 and they are perfectly fine with that too. Stock or modified. You dont need to mess about with octane booster.

Mines ECU's are notorious and you'll not find anyone recommending them. But you dont have one so it is not a concern.

Yeah nistune is what I have decided on. Any recommendations on workshops to have the mod done in melbourne? I have heard status tuning and chasers are worth looking at....

Status = Chequered = Recommended

Just bought an R32 in Japan.

So they are okay to run on 98? I have united 100 a couple of kms away but would be easier to run on 98.

Would prefer not to modify the tune, car is 100% stock.

Cheers

      Starting again

      By Ozdavroz · Posted

      So my R32 GTST has been sitting around at my old mum and dad's place for a few years now...and it's time to bring it home. Main issue I have is that she hasn't been started in about 5 years or so, so I'm not too keen on just kicking it over and hoping that RB20 reputation for being un-killlable extends to long periods of neglect. My plan is to get it running there so I can move it around,  then get it towed back to my place where I can start working on it properly. The old folks driveway is a bad place to start a project like that. I'm getting old too and also haven't stuffed around with cars since forever, so kinda learning this stuff again. So far I've siphoned out all the shitty old fuel and topped up the coolant (thought it was fully dry but took 2 litres to fill the radiator). Planning on hitting the rusty rotors with some brake cleaner in case the tow truck driver gets a bit gung ho loading it up. As far as oil, it's got plenty although it's now dark in colour and obviously needs a change sooner rather than later. Was doing some YouTube research and was planning to hand-crank the motor from the harmonic balancer with a 37mm socket and breaker bar, removing the spark plugs and spraying some "fogging oil" in the holes but there's not much room to get in there with the radiator fan right up against it. Jacking the car up takes too long and I can't leave it half done between visits. So now I'm was thinking of cranking a few times it using the starter (removing plugs and spraying oil first). Reckon there's any chance it will do more damage that way if something's stuck inside the motor? Should I really change all fluids completely before I go any further? Grateful for any other advice you guys have to get her going safely too.

      Well, that's just wierd. Amongst a string of seemingly benign introduction and request for help threads, we have this one with a link.... to another, unrelated thread inside this forum. Colour me suspicious.

      Import insurance in 2025

      By Duncan · Posted

      So it looks like Lumleys are closing other than in Victoria, with the kind offer that another brand from the evil IAG multi-glomerate (NRMA) might offer insurance under their price and conditions if they want to, as an alternative. Lunmleys was good for us because they covered JDM and USDM imports, had 2 car "stable" insurance (ie, insure many cars but max of 2 can be driven at once), covered mods, reasonable overall prices. So, with them gone, who else should I consider? Shannons is last on my list, we used to be insured with them until we found they were helpful at taking premiums but much less helpful at claim time.
