hey guys

I was woundering if getting 280 or so KM's out of a tank of fuel in a R34 GTT is normal. Thats not driving like a granny or redlining every gear....hehe

Cheers!

DAYUM! lolz the car is really in need of a tune if its not stock or in need of a really good service, oils, fluids, air filter, fuel filter, o2 sensor, etc.

for example if ur car is not stock i know a guy with a decently worked and tuned r33 gtst that makes in excess of 300kw atw and gets just over 400kms. so there is something definately wrong there.

might need to get your air to fuel ratio's fixed up as u might be running abit rich. does the car feel smooth coming on boost? any smoke when you give it abit? does exhaust fumes smell very petrolly?

the smell you are getting out of the exhaust may indicate stuffed cats. both of my cats were blocked when i got my car and it gave off a really bad smell out of the exhaust and were blocking the exhaust flow. changed the cats, smell went away and got a small increase in fuel economy.

i'd also be inspecting all your fuel lines and also the fuel filler neck (they change the insert during compliance and sometimes it leaks). also check your o2 sensor is working correctly, clean your coolant temp sensor and check for any error codes using consult or datascan.

Yea what he said ^^ my car seemed to be running rich before so I changed the O2 sensor afterwords I was running noticeably leaner, and the fuel gauge goes down a lot slower (Havn't gone through a full tank yet)

i get 310kms to 1/2 then bout 150kms till empty on my rb20det in my r32, and its running rich as with black shit all over my rear bar. I just dont get how it uses so much in the last half, i drive normal 90% of the time nothing over 4.5 rpm so its got me stunned

The fuel guage thing will just be the intank gauge. My rx7 did the same thing after we installed a new fuel pump because we bent the bracket a little.

On topic, my r34 gets 450km from 50lt combined cycle. Mostly stock, exhaust/pod/safc/probfec B, 186rwkw.

I'd try your O2 sensor

have u got atmo BOV? this will do it every time

otherwise probably O2 sensor

Yeah i got bov its a Turbosmart Dual port.

You can turn the top of it to open and close the vent inside. I have it Fully open. Can this be the reason?

I think its getting worse for some reason. The other night i chuck 20 litres of V Power in. Got Just under half tank. So far I've drove like 26K'm. And its gone down a bar....wtf?

i was happy when i drove 'more' normal and got 345km to a tank. would have got more but we have a road thats 27.3km paved before a few hundred km's of gravel, all twisties to avoid being bombed in ww2 and i usally lose 3/16's+ of a tank making a quick run (120 in 2 places, 140 everywhere else with 2 200+ spots)

But i averaged 260km - 310km most of the summer running a full tank down to 1/8.

mods :

all sensors cleaned

Stock 270cc injectors

Wolbro 255l

Nismo reg (56psi)

front facing plenum with 4 3/4" thick intercooler with 3" piping

Greddy td05 16g (1 to 1.3bar)

hks silent exaust turbo back with no cat

Greddy oil air seperator, oil filter relocation, breather tank

Act clutch, Nismo flywheel, Nismo solid shifter

and a Mines tuned ecu not tuned for the mods

Fuel was 94 octane ehtanol blended fuel running a shot of NOS Racing octane boost with every tank (never ran 100% without that exact combo of products)

Kinda funny seeing how proper tunes make all the difference in mileage. When i get my 550cc injectors z32 maf and to4e installed i'll send in the Mines unit to get retuned.

Try cleanaing or replacing your o2 sensour, clean your maf sensour and change out your fuel filter. Remeber that even the slightest increase in throttle position makes a tiny chain reaction that'll burn noticeably more fuel without much more gain in speed every little bit of turbo usage will effect your fuel consumption. Get a boost and air fuel gauge and you'll be susprised what even small changes in driving habit/style makes to overall fuel consumption.

But for the most part i just said screw it, i paid good money and worked my ass off working on this car and i'll be damned if i drive it like an econo-car. PEDAL TO THE METAL, AND LETS SEE HOW MANY GEARS SHE'LL KEEP SPINNIN THEM AT.

    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
