Hey guys just joined up and did a search, no results so here goes.

Looking at a R33 on this forum and need to know ball park figures for fuel economy.

I have never owned a boosted car before so do not really have a good grip on fuel consumption for such a car.

Also anything to look out for when buying one (set on a R33) such as common faults from production etc.

Thanks guys

Joel

There have been a few threads on this. Mine did about 14L/100km in the winter on the stock ECU (with intercooler, exhaust, pod), now does around 12.5-13L/100km and the only reason i can give is hotter weather. Stockers should do 10-11L/100km from factory specs. A Power FC or other aftermarket computer helps lower fuel consumption on modified cars back to near stock when cruising.

There's a thread here for what to look out for when buying a Skyline.

fuel economy depends on how you drive it. i drive rather 'spiritedly' and i get about 16-17L/100k. i have full exhaust, pod, frount mount and 14psi. that is city driving. on the highway (even if its just 80kmh zones) it drops to about 11L/100k.

R33 GTST

mild hi-flowed turbo @ 1bar, PFC, fuel pump, reg, full 3" exh, pod ~210rwkw

Consistent 450km/55L - 12.2L/100km

Highway driving ~600/55L - 9.17L/100km

lazy-bastard: thats mad fuel economy, my car struggles to see ~340 to a tank and thats normal everyday driving. Will my fuel economy increase by heaps with a pfc?

my brother has spoken to a few drifters and they get consistand 400+ to a tank even though they have over 250kw.

i think its tune dependant i think. Im running 209kw on 12psi and im on around 11-12 psi everyday, fuel economy is poor. I have been told by tuners and others that my fuel economy will be heaps better with 250kw and a pfc.

My car had an SAFC2 when I bought it and I was getting about 400ks/55L, so the PFC tune did improve economy a bit.

fair enough, i think if you have a conservative tune, then you will see good km's to a tank. Instead of dumping a whole heap of fuel for no reason, you use every bit of fuel that is allowed in.

1998 R33 gts25t manual completly standard, i could get 500km for a full tank driving it like a granny, i normally get about 200-240km from half a tank of 95 octane depending on how it drive it.

I got my SAFC II tuned and i managed to pick up about 50 ks in town, if i drive it now i would see 400 km in town out of 55 liters but highway is only about 500 if driven nice. I have already changed the O2 sensor and makes no differance.

On average i fill up with 35-40L and get around 350-450k to a tank depending on the type of driving i am doing

Mods are just a exhaust & air filter

I read somewhere that they are meant to do 9L/100k....

I get around 14-15 l/p100k's around town if i drive carefully.... If I hammer it, it can be as high as 19!!!

Just did a run from Cairns to Cooktown and it averaged 14.5. That was sitting at 130kph-150kph (open roads with no-one on them - just gotta watch for cows and roos)

On the way home I sat 110-120kph and I think that has improves it to around 12....

That is in a series II R33 with exhaust and 10psi.......

:(

  • 7 months later...

Guys when doing highway trip i dont get much more out of a tank then if i am city cruising..

I get about 380-400km from 50 liters in the city pretty consistantly, but do a 200k round trip on the highway in there too and am lucky to see 420-430 from 50 litres.. I would have expected above 450km's from 50 ltrs.

Is this a sign my o2 sensor may need replacing, or is this common for a skyline not to get good highway economy.. This is my 2nd r33 and both cars were the same.

Series 1 rb25det exhaust, cooler, pod, 8-9 psi, .8mm copper plugs which are newish...

    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
