Hey guys,

I have a r33 RB20E

I'm getting 250kms per tank on ultimate, and 300kms per tank on optimax, just had new plugs, new oil, etc. I only rev out gears occasionally, and i cant seem to work out why my fuel economy is so damn bad!

Ive put up with it long enough, but now its past a joke!

I only live 5-10kms from school so it does do a fair few cold starts a week...

Can someone suggest how i can go about fixing this? and getting a bit more kms out of my tank, i dont have any complaints about the car bar that. I was thinking dyno tune, but what else is there?? and is this even possible with the stock ECU. Also, is there anything i can buy aftermarket to make the situation better? can i advance timing etc??

Thanks guys....

Dayne

hmm... 250-300 to the tank is quite poor.. specially in a 2L car...

I wud recommend maybe try resetting the ECU? (there are threads - try a search)

clean the afm? but yeah a dyno sounds like a good idea and will save u from mucking

around - check the AFRs and see how it goes.

keep us updated man.

Yeah, now i just need a few more things and it'll be sweet:)

Yeah its a series 1.5 R33 skyline with an Rb20E

Pretty strange i thought too, but it'll do for the time being, might even turbo it, but i dont think it'll be worth the hassles, just sell up and buy one already done!!

Thanks again for all your help!!

Anyone needs a new sensor, repco sell them i baught a ford EL one, got it for $85!

      The Evolution Of "night Fury"

      Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
