hey guys just got my r34 gtt but the 'aftermarket' manual mentions only unleaded fule - it doesn't specfy if it needs to be premium 95/98RON or if the standard 91RON is fine

what's generally recommended for the r34 gtt (manual) with stock everything? Cheers

filled 'er up with bp ultimate. My first tank .. cross my fingers my fuel economy isn't as bad as some of the horror stories I've heard around SAU (250km to a tank etc)

I just cracked 220 at the half way mark :)

Hmm this is a bit worrying... I've just got 300k out of 50l of BP Ultimate so that's approx. 17l/100kms, yet everyone here seems to be getting 400-500kms per tank.

I got the car last week and I think the dealer 'tuned' the computer or atleast I heard something along the lines. Could it be they've screwed up the fuel economy at the same time?? The only aftermaket mod I have right now is a 3" turbo back exhaust and bigger wheels. I haven't been 'racing' the car but it's mostly stop n go (under 70kmh) sort of traffic through the city with no highway driving whatsoever.

What do you guys think?

lol mate i think they're is something wrong with your car. R34GTT? 17l/100kms doesnt look right at all. :)

Unless you've been stuck in really horrible not moving traffic. You checked to make sure you're not leaking oil?

my advice would be to take it to a mechanic to check it out if you're continuously on 17l/100kms.

nothing to worry about. 300km out of 50 litres is still ok. Thats 16.67L/100km. You said it was city driving stop start up to 70km "no highway driving" And you said you've only had this car for a week, so of course you would be doing some "spirited driving" lol. You will get round 12L/100km with highway driving. And your economy will settle after you've had the car for a few more months im sure.

Few things to try on your 34 to get the fuel consumption down. Replace the O2 sensor, you can do this quite simply by removing the O2 sensor you've got and going down to repco for a replacement bosch unit. And disconnecting your battery to reset your ecu. Hopefully in a couple of tanks your ecu will have relearnt your driving habits and fuel consumption should level out again. Btw, always run 98 :D

This might also be of interest to you

      BTW, the reason I came in here to "update" this list was that the Garrett G Series II range have been released and I've updated the list with their flow details if you're curious to check how they fit with previous Garretts and other brands The G-Series II G35 990 looks like a banger...

      Hi all, I thought I'd put one of these references in here before but it seems I haven't - not sure how many people are actually using this place still but I feel like there are guys lurking about who might find this reference useful or interesting.  A lot of the time people don't catch key details or even fully understand how compressor maps work - or don't even look at them and just go from heresay about deciding how different turbos may compare, but I've been putting together this table over the years as a quick reference to get a gauge of how certain compressors compare to cut down the time that can be wasted looking around aimlessly. * This relates purely to compressor flow, so won't necessarily reflect the outright capabilities of these turbos as the power potential also comes down to the turbine side.  If you understand this, you should be able to use this 😃 * The inducer and exducer size listed are the mm of just the compressor wheel * The values under the "psi" headings are "lb/min airflow" and reflect the maximum airflow that compressor supports before it's efficiency dips under 65%, or it reaches it's maximum speed - whichever comes first. Any questions, or requests for other turbos which the compressor map is available for then let me know 🙂

      And what you pay for a pack of 8 bolts and nuts at Bunnings, will land me 200 of the same nuts and bolts from a fastener shop.   M12 * 1.25 IS a standard. It's not like ordering M12x1.25 and hoping the thread pitch is right. Unlike ordering an ounce, will get you 4 different amounts depending on which ounce someone takes it to be. Your issue is a supply issue.
