Hi all,

Would it be OK to fill up the R34 GTT with 91 RON petrol and then treat it with Nylon Pro octane booster?

From the reviews Ive read, Nylon Pro is the bets one out there and raises the octane rating past 98 PULP.

Its just I can get access to 91 petrol but not 98... atm.

If that's all you can get where you are atm, then it'd be best to do just that.

Whatever your mean average RON is, sitting in your tank atm, the octane booster is only going to shift it up marginally.

You'll get a better result with toluene (ie methylbenzene), depending on what amount you put in; but through regular skin contact and inhalation, it's carcinogenic.

if you got 98pulp in your tank and you drop in octane boost

how much more would it raise the pulp?

105pulp?

Doesn't quite work like that mate. As in theory adding more octane booster again would give you 111RON, then 118RON. Until you ended up with 300RON super fuel to run an engine with 37:1 compression...... laugh.gif

Running Octane booster in general is a bad idea.

A once off is ok for emergencies... But then you can just stay off boost/light throttle and you'd be fine.

If you keep using it you'll run the chance of fouling plugs after a few tanks, and that'll make it just 10x worse over time than using proper fuel :)

a mate of mine was a mechanic for repco a few years ago (the local repco store had a workshop on the side of it) and one day the nulon rep came through and had an octane test kit with him. my mate grabbed some BP ultimate out of his car and they ran a few tests. first they tested the fuel by itself. it was 98 octane (as you wuold expect). next they put in the standard measure of the pro strength octane booster (i think. this was about 5 years ago now so the memory is a bit dodgy). pretty sure this put it up to about 103 octane. then they put in double the normal dosage. the octane rating actually dropped back down to around 99 octane.

just run it on 91, unless you have an aftermarket ecu tuned for 98 it wont be a problem. with a stock ecu your better off with 91 than 98 anyway.

if you use octane boost make sure you have plenty of cash for spark plugs, you'll be changing them every 2nd tank. not to mention o2 sensors and other shit like that

are you missing that he said it was for a GTT, or are you taking the piss? the stock turbo ecu is tuned for minimum 95 octane fuel. running it on 91 octane will result in a loss of power, or if the knock sensors aren't working correctly a damaged motor. 95 or 98 octane will result it more power and safer knock levels.

Most people know that Australian 91RON unleaded is basically served as shots in Japanese bars... Our fuel sucks. Thus, imports not originally made for the Australian market should be run on 95 or better...

    • This. A 3d wheel alignment is like $120...just take it to the shop. Since theres probably multiple adjustments that need to be made after changing something. Mine has front/rear lower arms, traction rods, tension rods, camber arms, toe arms, front upper arms, hicas kit, sway bars and coilovers. I measure from the edge of the bolt holes on the originals and set the same length on all the adjustable stuff to dial it as close as I could to OEM. Took it straight for alignment; it didnt feel right at all...after alignment, it feels perfect. Similarly i've just changed the springs on another car; and I still needed multiple adjustments to bring it back in spec.
    • A full Veilside kitted JZA80 Supra in Meriken park in Kobe city a few weeks back
    • Its a well known brand in New Zealand; its a rebrand of the Rhino RAV3.  I don't know what the wiring difference *is* between the rev.1 (installed about 15 years ago) and rev.2; but as you say I would think its reasonable that it uses the same immobiliser relay circuits. I had a look but couldnt see a similar harness; but didnt move things around since I didnt want to mess with it   It was one of AVS well known Authorised Installers; I spoke to AVS themselves about it but theyre unsure hence seeking advice more so from the skyline community who are more familiar with the actual car and its wiring. Im in Auckland; but the installer is on the other side of the city so hes very reluctant to come back to even look at it to confirm something isnt connected into the wrong wire.  I dont want to drop the name since they *did* do a really good job for the most part. Everything is very tidy and he fully replaced all the alarm wiring, all the sensors, the wiring to the door motors, installed a switch which was never installed in the first place...really happy with the alarm install itself..just not this one issue. We all make mistakes, if it is the alarm, I just want my fuel pump getting proper switched, fused, power as it was; without having to shell out for an auto electrician to switch a wire and tell me it was the alarm. 
    • Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.
    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
