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...

      R34 Gtt Wheel Offset Advice

      What can't be done with a little bit of decking board or similar timber bolted to a hub flange via 2 wheel nuts is not worth talking about.

      R34 GTT idle problem

      By silviaz · Posted

      I noticed something. On the tps sensor and the sensor behind the adjustment screw is adjusted towards the far left. Are these screws supposed to be centered? (this sensor was in the same position before the tune as well)  Also attached a photo of where my car usually idles at when warm (sometimes a tiny bit above that). I think I might have screwed up the calculation and it might have better than I thought lol at 750rpm still not 650rpm though.

      So for both general interest of engine health, and to rule out any coolant/oil issues, I organised an oil analysis done on the 125,000klm oil Results below, all good, just a bit of fuel dilution which I'm not too worried about

      This is actually a really good way of measuring what wheels fit. If only there was a similar measurement between hub face and suspension :p That said, it's probably pretty simple to actually measure it all with the wheel off the car for the rear. The front is a bit more complex but..

      R34 Gtt Wheel Offset Advice

      By AdiR34 · Posted

      Being the top Google search result for R34 wheel-related inquiries, lemme throw down my experience. I calculated that 100mm from hub face to wheel face is about the perfect fitment for my ENR34 sedan.  I've been running 18x8.5s, ET35, with a 1" spacer. So, 8.5in to mm = 216mm. 216/2 = 108mm. 108-35 = 73mm. 73+ 25 (1" to mm) = 98mm.  If you wanna get close to this on dif widths, here are the offsets you'll want: 9" - ET around 15mm 9.5" - ET around 20mm 10" - you're crazy, but ET around 30mm All these should fit perfectly on a non-widebody, non-GTR Skyline. Note that it's probably the absolute max, and you're probably better off running a couple degrees of camber in this config, but it looks great, super flush.
