Hey guys

Just wondering about economy for your Cefs, ive got a commodore im thinking of swapping for a ceff

Yes, ive done a search and didnt find anything (maybe i looked in the wrong place? if i did please let me know :( )

I currently get around 500k's to a full tank in city driving, heaps more on the interstate highways, but the car doesnt handle at all and is really too big for me day by day

So, post up how many k's you get, what motor (auto or man) and how hard you drive it - cheers :huh:

Something like this would be great

Year model:

Motor:

Man/Auto:

Average k's p/tank:

Hows it driven:

Mods:

What would you change about it if you could:

Thanks HEAPS guys :P

Share on other sites

Year model: 1990

Motor: RB20DET

Man/Auto: Auto

Average k's p/tank: 520km average (65L tank tho)

Hows it driven: By my 57 year old dad, to and from work and shops

Mods: pod, exhaust

What would you change about it if you could: sell it and buy a prius coz dad bitches to no end about wanting a more fuel economical car (dosen't really wanna go fast anymore).

Year model: 1989

Motor: RB20DET

Man/Auto: Manual

Average k's p/tank: 450ish from memory, although havent filled up a full tank for awhile now with these fuel prices...

Hows it driven: Moderate (bit of everything, like a granny to work which is short distance so probably on rich tune there and back - also with a bit of a blast on some weekends etc)

Mods: Pod, some crappy restrictive exhaust, mainly stock to say the least.

What would you change about it if you could: Throw the rb20 out and use it as a boat anchor and put a 1jz or 1uz in...hmm :mad:

Year model: 1990

Motor: RB20DET

Man/Auto: Manual

Average k's p/tank: ~420ish (~500 for freeway)

Hows it driven: Race driver? lol i rarely change gears below 4k, usually around 6, unless it still warming up.

Mods: Pod, Exhaust, HD clutch, Alloy Rad, oil cooler, boost @ 0.8 bar with GFB bleed valve.

What would you change about it if you could: If i could, i would add an aftermarket turbo. :mad: I know it runs rich as a mofo, for example it went to 9:1 afr on the dyno and sat there from about 4k onwards. A powerfc or remap would increase fuel economy.

Well for starters, a cef aint any smaller than a commodore.

I'm getting about 570kms per tank, combo driving, highway and gateway traffic every morning and afternoon, and thats not my best thats the average, about 55-57L will go in the tank when I fill up. If it was to be all highway Id crack the 700kms with easy I feel.

Mods being pod, exaust, 12psi, dr drift chip, and adj fuel pressure reg.

Its a 1988 manual rb20, but with a RB25 box behind it, and a 2 way diff (no idea what difference that makes in terms of fuel economy).

But thats on 98ron fuel, which is 10-12c more per L up here in QLD.

Changes I would make, Id turn it in to a Subaru Liberty Blitzen :)

1990

Rb20de

Auto

2 1/2 inch cat back

drivin - depends what mood i'm in. usually fairly easy going

not much country driving.

i get about 10-10.5 km/L

i'd get a manual gearbox, go the rb25 box

Guest a31rb25

Year model: 1990

Motor: RB25DET

Man/Auto: Manual

Average k's p/tank: approx 300

Hows it driven: pretty sedately due to the shit mileage

Mods: usual mods- pod, FMIC, etc

What would you change about it if you could: RB20 computer, remapped by Dr Drift for + KKR 480 turbo

NOTE: ATM i get no mileage at all, car isn't being driven, don't lose your license, it sucks.

Edited by a31rb25

OMFG did i just read this right...... Steve has finally seen the light... :sorcerer:

Mate i would love to add my milage input but i only know it goes thru about 2 tanks in a track day :)

BUY A CEFFIE YOU KNOW U WANNA!!!! :rofl:

Year model: 88

Motor: rb20det

Man/Auto: manual

Average k's p/tank: less then 100kms... prob around 50 kms max

Hows it driven: hard and sideways

Mods: lots, 200 rwkw and its a drift car and for track use only :)

What would you change about it if you could: 1jz :rofl:

Wow, thanks for the responses guys :rofl:

Lots of mixed k's in there (as i was expecting)

Ive just done a 511k tank with the holden, and so far this week i will beat that, so i think for now, the holden stays :unsure:

Not only the petrol is the deciding factor though, but the stereo, sunroof, climate control, cruise control are all nice things ive grown to live with, and i really dont think i can go without now in a daily driver

Thanks again guys - REALLY appreciated :(

Year model:1991

Motor: 1JZ GTE

Man/Auto: Manual

Average k's p/tank: 300-350 on short local runs, and 350-400 on a long run using highways [and not on boost all the time]

Hows it driven: hard....

Mods: standard engine, with KnN air-filter, standard blow-off, 3 inch exhaust with front silencers removed

What would you change about it if you could: bigger turbo and bigger fuel injectors.... blitz blow-off and blitz wastegate and a huge exhaust back-box.

Year model: 89

Motor:RB20DET

Man/Auto: Man

Average k's p/tank: 400 only, get 450 if i push it.

Hows it driven: To work and back in pretty heavy traffic. Lots of start and stop, then i give it a bit on the weekends. Still pretty crappy though, think the O2 sensor needs replacing

Mods: FMIC, RB25 turbo, pump, remap, stock air box.

What would you change about it if you could: 1JZ conversion, softer spring rates for the street. respray.

Hey steve... pulled one of the shocks out today at Bel Garage... the shocks need to be regassed or changed... hence the floatyness.

I also bought some shims off nissan to lock teh factory viscous diff.

stay tuned for dad's undercover dorifto machine.

    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
    • street use or race track, what hose size and why? what factors change with the hose size options ?   see most comon is an10. when you see most oem external coolers are closer to an12? does high volume oil pump like nitto need an12 or 10 be just fine
