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.

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.......

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...

      How dare you sell your unreliable Skyline and buy a reliable, Toyota/Yamaha car with a strong gearbox, torsen LSD and Toyota reliability. At least you won't need to worry about oil pumps, big catch can, oil restrictors, blowing off power steering belts, sheering off 3rd gear, failing ABS relays/pumps, etc.

      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?

      Leak from Tokico BM50 Brake Master Cylinder

      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/
