Hey all, I recently went away with my GF, thankfully we took her car because i was amazed to find that servos in country towns don't sell 98 octane fuel..

Were looking to go away in my skyline ( R33 RB25DET ) next time but the problem i have is, How am i going to get 98 octane fuel if places don't sell it, I found the lowest they had was 95% octane, So what are the choice's i have? Bring alot of jery cans lol or use 95% octane and just add half a bottle of octane booster to the tank? ( or how ever much you need )

Thanks, Russ.

Nah, i have a PowerFC and a bunch of other things lol, Running 13psi also..

in that case HELL NO, only as a last resort should u go 95ron if 98 isnt available.

for someone who seems to have good stuff on their car and put in all that work, u seem to be willing to throw it away on suspect fuel.

just when 95ron is in there, take it easy eh

Mate you think that you have a problem.

I run my GTR on V Power Racing that in NSW you can only buy in Sydney and Canberra so whenever I go anywhere else I carry an extra 50 litres of fuel in the boot so I can get home.

This is a bit of a pain but it is tuned to run on 100 RON and has performance to match - the things people do.

It will be fine if you limp it; run it near empty then push a tank of 98 in to it.

Don't even think about giving it a little hit.

Once tuned mine would ping its arse with 1/4 throttle bringing it up on boost in an attempt to slow overtake..

Be carefull of those ring lands.

stock car?

look under your bonnet mate.

recommended fuel is 95RON min.

95 is fine if its still got stock ecu etc.

Can anyone confirm this? I thought 98RON was the recommended fuel, NOT 95.

I drive a stock R34 that only has aftermarket exhaust and pod. I have only ever used 98 fuel, but are you saying I could now switch to 95?

you mean shell v power???? r33's are recommended for 95 ron or higher, no it doesn't matter if you mix them, but you don't get the full benefit of 98 ron fuel.... also if your worried about the 95 ron jsut don't give our car a hard time

nah not shell V power. I thought it was Shell V power. but it was Shell Premium unleaded.

And now my car is making a weird noise. like grindin ish and goes away and come back. engine shakes a little. just after i filled up.

its coming from the front of the engine near the fan.

Yeah wont give it a hard time. will just go put 98 in and mix it in a few mins.

Hope all the shitty noises are coz of the fuel.

Yeah, can anyone confirm? I thought it was 98 as well (well best we got here anyway...) & on the inside of the little door that leads to the petrol tank, I got a green sticker that says "some jap words" & 100, I think that its saying recommand RON 100?

I wouldnt put anything less then 98 in mine, and havent done so since i got it. Japanese fuel is higher octane then australian fuel generally so id exect the minimum to be 98

I know people that have run there fairly stock skylines on 95 but it isnt terribly safe.

id buy some octane booster to put in with every tank, peace of mind for an extra $10-$20 a tank really...

    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
