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!

      Forced Performance Hta Turbos

      By LaurelPWR · Posted

      Dredgggggeeee time; I have recently finally started driving the car. It sat for so long that the fuel tank gave birth to rust sludge and blocked my lift pump sock and one of my walbro 460's and left grime, rust chunks and muck all through the surge tank and system. I decided to commit and pull the trigger on an oem r32 gtr fuel tank and Frenchys twin 460 / sender / surge tank hanger combo and all new larger lines and fittings etc, also boost doc heater hose kit / new heater core and a heap of other bits and shits like wideband sensor installed in the dump and Syltech iacv + lines and all wired and added to current tune. now having lightly driven it a couple times without issue, I can happily report on the hta3076 in its current tune. still no boost control switched on, 20psi gate springs, car makes 22psi at 3200rpm in 6th gear with 30-50% TPS from cruise at 100kmh. Going by the old graph, this means it should be making 300-325whp at the same numbers above. Very very responsive setup under true road driving loads. all that's left for the build is body loom + PDM, finish the remote aircon setup, install carbon fibre parts and go for full tune and 30psi. the 315 rear tyres are now performing like they're 195's, wheel spin in any gear at almost any rpm, whereas my previous setup hooked up in 3rd no issue, albeit Nt01's back then / RB25 5spd vs (new) old date r888r's Z34 6spd now, + obviously all the support upgrades I listed in the quoted post above. car sits at 1-3psi on cruise at 100kmh, expectations totally exceeded and I'm beyond stoked with all this so far.

      Crank Motorsports Front Axles

      I've also been eyeing their rear axles for my car. I purchased seat mounts from them about 7 years ago and they were hot garbage so I've been a little wary about purchasing them. With that being said, please buy them and get back to us haha.

      Being a manual, we very quickly ordered new R34 gearbox (From Nissan) and remaining parts from Kudos motorsports. Would highly recommend the team there. Ultra helpful and quick to share advice and upgrades. We are in the middle of taking the Auto out (Genuine 94,000/kms) and putting the Manual in this weekend. Part 2 of the build will include likely a Plazaman Intercooler and Plenium, Hks Exhaust with Tomei Dump (ordered).
