Better Highway Consumption...

[benm]

Randy:

- Your car is stock so it naturally running very rich.

- You easily have another 10L of fuel that could be used so theirs another 100km minimum (i'd consistently use 60-63L per fill up when I had my R33 GTS-t).

[Cubes]

What sized tank do the 33's have? I was under the impression it was the same as the R32's.. Being ~60litres.

The redlight comes on when there's ~10litres left in the tank, I fill up at this point and can squeeze 50-53 litres in depending how long I've driven on the redlight.

[benm]

Nah the tanks are up around 67L.

[gtst25]

I thought the r33's are 55 litres.

When my needle is on empty I can put 50 litres in.

I'm sure I read the 55 litres somewhere - it must be in a manual or something.

Interestingly I seem to get better economy when driving at 110km/hr plus - it doesn't seem to have to work as hard at that speed with the little boost that its making then and just rolls up the hills.

At 90 - 100 you have to put your foot down a lot more - it doesn't feel happy.

I'd love to fit a na rb30 bottom end and make the gearing a bit taller - first gear is a bit of a waste of time in my r33.

cheers

they are 65L

if u overfill a bit maybe slightly more as ben has found.

light flashes when 15L left, light goes on steady with 10L left.

[RANDY]

Ben and others, cheers... regardless of how much is left in the tank, 50L takes me 350k's. Do the math on that, and it's what? 7km a litre? I'll be putting on a split dump, cat, exhaust on next year... so hopefully that will lean it out a little?

the most petrol i can put in my tank is about 47 litres

thats from the guage reading below E to over F

thats r32 gtst

[gtst25]

Just had a look in the sky is the limit skyline book and it says for the r32 gtr the fuel tank is 72 litres, and r32 gtst 2 and 4 door 60 litres.

Nothing in there though about the r33's.

If I'm putting 50 litres in at 500 k's and it takes 65 litres then that means I can get well over 600 to a tank!

Yep you were right - it says the rb20e, rb25de and rb25det r33's are 67 litres - maybe I shouldn't worry so much when I hit empty!

Cheers

I used to run mine till the needle hit the top of the 'E'. Obviously it's picking up everything from the bottom of the tank but I figure that's what a fuel filter is for (when changed often). I did it for 2yrs and never had a problem (didn't get any fuel surge either).

In my GTR i'm definitely keeping it above 1/4 at all times.

[Guilt-Toy]

Has anyone got a Rb30DET and injectors around the 740cc size get any good economy on crooze?

[Pal]

my r33 auto's got safc, 3" exhaust, stock turbo, at 10 psi and cant get 400 out of tank even when cruzing? i think i worked it out to 13.5l/100k's

up around small V8 consumption?????

and just got it tuned:-(

and just spent $200 on a original nissan o2 sensor

Well... my VP V8 used 70L to give me 380 on the dot, every time.

So my new 350/50L isn't too bad in comparison... but still lousy if you work out the km's/litre

[Cubes]

wow.. The VP's were quite a bit more heavier on fuel than the VS 5ltrs.

My VS before the ecu and cam would get around 450km's to a tank, after the ecu and cam it was pretty much the same. On the open road it would crack 650km's per tank easily.

I can't remember exactly how big the tank was in it but at the time it used to cost a lot to fill at .59c per litre.

if i went the whole 65lt tank my rb20 can do 780km highway driving, has chip and rb25 turbo

[benl1981]

Hey taken it easy lately and slightly longer drives in the 33gtst. Just done 300km and I'm just under a 1/2 tank. Probably getting 9-10L/100km. Must make a difference with the throttle application.

In my corolla I could deck it everywhere, use heaps of revs and not change consumption much.

I am on the base map still.

I also have to get a wheel alignment which could possibly make a little difference if the toe is out.
