HELLO i own a R34 coupe 2.5ltr neo, tiptronic auto ewww, has a K&N air filter, removed the cat, new iridium sparkplugs, well serviced only done 100K... the problem is i fill it up at $80-$90 right to the top about 60ltrs i think and it only goes as far as 400k-430k depending on how i drive it!!! ive had it hooked up on the scanner tool and all the sensors are fine. thinking of some performance chip in future aswell but not if it going to drain more fuel and yes i will be getting and exhaust extractor and putting a manual in soon .. the point is that i should get 100km to 9.5ltr-10.5ltrs of gas.. any ideas if there could be something else wrong...cheers

BTW if you do a search theres 11tybillion threads on similar topics

yes there is heaps of threads on this but none to do with later models, i have heard about the vct on the neo heads can sometimes put the timing out

just thinking out loud here.

seems like the NAs no longer get the fuel efficiency they used to. wonder why?

back when i first got my car, i'd get 500km+ easily... 600 when i took it for highway, easy drives.

is it the fuel or the age of these cars? two of my mate's gtsts (one is stockish, runs high 13s. one has 250+rwkw, runs mid 12s) both get something like 400-450km/tank driving off boost.

Funny, mine did the opposite. When i got it it was getting about 330-40kms to a tank (9km/l), and now i'm getting around 600kms. The only thing i changed was running V-Power for a while while it was cheap, and then kept running vortex or Unleaded 95 from shell.

i got about 480k's out of my last tank of v power racing... the fuel light was on and off for like 3 days... never been so scared in my life! :blink:

i normally aim for 400, my needle is pretty low about then, but theres still about 15litres left in there...

im running a GTS-T though, and often run it boosted...

woah thats incredibly depressing...

i get around 500k's to a tank average driving with my beast :blink:

your economy is not normal people, maybe professionally clean injectors, new 02, clean afm, make sure the engines in good service and tune (plugs, timing) check compression... no exhaust leaks? smash it on the dyno, check out a/f?

invest in a safc and lean out your mixes :P

I'm getting about 330 till the fuel lights come on.

I think I average about 100km for every line. 3/4 tank = done 100km.. roughly..

would LOVE to learn how make my car go further every tank..

cheers

Exactly the same.

I seem to get close to 100km per line, then it just drops bad when it goes past half way haha.

R33GTST - I average 500kms per 45-50L - 70%-80% is freeway driving though .....

yeah i do about 5% freeway/motorway driving... depends where i go on the weekend... even then, im probably in a rush and still boosting it :P

my fuel economy is about right... probably a little better then normal... im not very conservative with fuel, yet it goes pretty far :D

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
