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

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.
