RB20DET, Stock turbo 15psi 164rwkw

City: 470km's per ~50litres. That is until the red light first shows.

Open Road: Not sure have never taken it on a full tank.

WOT: Booting it the RB20DET would drop fuel economy to low 400's per tank.

Driving style didn't appear to make much difference to fuel economy.

RB30DET - Stock rb20det turbo 176rwkw 9psi.

City: 450km's per 50litres.

Open Road: Again. Not sure.

WOT: Booting it the RB30DET drops to 380km's per tank.

I'm scared to start swapping out the stock injectors incase fuel economy goes to the sh*t. :D

Mind you Bl4ck32 has 550cc rx7 injectors thats all been tuned up, his rb30det in his r32 tends to get slightly better fuel economy than mine.

ive found a trend in my car. it's basically always KMs/10 + 10 = Litres of fuel

so 350kms = 45L filled up

400km = 50L filled up ... and so on

my 33's usage was similar

so far ive only had one tank which was used for pure thrashing and i did about 250km in 55Ls :D

freeway driving is typically a lot better than the formula above.. the other day after filling up, i drove 130kms. then i pulled over and filled it up again, and i only put in 16Ls..

edit: i just realised that the above does not apply to u as i have an rb25det in my 32.. lol sorry.

Hiya,

I've got an R32 GTS-t manual and I get roughly 380-400km out of the tank of regular city/suburban driving.

just did a drive up to Sydney and back a few weeks ago before that dreaded fuel increase and estimated with general cruising averaging 115-120km/h I could get around 600km to the tank.

Mind you though the car's running an aftermarket replacement ECU and it doesn't run an airflow metre anymore so I was expecting it to drink more than that... :)

Fuel tanks get a build up of crap over the years. A friend of mine had a vl turbo that used to run really rough whenever the fuel gauge went below 1/4. Thats the worst I've ever seen.

You could fix it by taking the fuel tank out and cleaning it out, but that is just sooooo much effort, much easier to just keep a nice amount of fuel in there. :)

    • There's a good German place in Brisbane if youre up for the drive 😛
    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
