i am getting some really bad fuel economy lately have been pushing to get 320km be for 3/4 empty mark. with full town driving. not overly heavy right foot

Dude thats not actually that bad.

You'll find most R34's will get about 120km per 1/4 line on the gauge, and if you are doing that you are doing well.

So 3/4 you'd maybe expect 360 which is very good, and if you are getting 320, I'm pretty certain thats fine.

At your rate you are probably getting 12.5/13L per 100km.

i just filled mine up, R34 GTT manual.

So far its about half way down between the top and line below, and its done 105kms

nice... that's what 8-9L/100kms? All highway driving?

You should keep a petrol log though.. mine usually lasts a little longer on the first quarter than it does on the last two quarters, the lines are not really an accurate measure.

nope. mostly town driving howie. apart from just after i filled it up. i did a 20 minute stint on the highway. so its going alright. but yes the gauge is now dropping faster then before haha

on the drive home from picking the car up, my fuel consumption was great. I think I could have made brisbane to rocky on one tank. which is 700odd kms. Was extremely impressed with its highway consumption!

I have minor mods (filter, fmic, boost cont.) at the moment and im getting about 430kms before im in the red! Thats city and country driving on premium fuel. Pretty happy with that compared to other cars with similar power range!

Hi All,

Just wondering if the R34 Neo RB25DET fuel consumption is similiar to that of the R33 RB25DET? Better or Worse? just wondering if the VVT side of things made any difference? My r33 gtst was getting about 380-400kms tank (no thrashing mainly highway driving).

thanks.

I can get about 450 or so if I drive sedately with no AC. Mine is totally standard though. I have had closer to 500 on a freeway drive though. I was quite surpised at how efficient it is compared to my old GTR.

Found this somewhere, hope it helps

They look like factory quotes.

I dont know how factories come up with these figures, even with other non Nissan cars they seem grossly underestimated.

Sorry to revive an old thread but only just recently i bought my R34 GTT Auto.

I have a S14 SR20DET Manual also. I get around 500-600kms to a tank in the S14 and im pretty sure they have a 65L tank also. I have a few mods on this and running 10AFRS so quite rich lol.

By the sounds of it most u guys just fill up when the fuel light comes on, now i no it not the best to take the tank down to the last tiny bit of fuel left init but in my S14 i got an extra 70kms to a tank without it chugging or anythn when it hit the fuel light.

Are the pick ups on the stock R34 pumps high??

At the moment the fuel econmony im gettn in my R34 is a bit poo really. ONE BIG QUESTION I HAVE IS-

I try use tiptronic to use the revs more when taking off at lights etc... eg. Instead of having to put your foot into it more just in nrml auto mode i take it to bout 3,000rpm in 1st and 2nd gear with HEAPS less throttle and get to the same speed about the same time.

Has any1 seen a jump in better or worse doing this??????

THANKS

I have a BCNR33 RB26 in my GTT with the stock GTT pump... running leeeean and I hate it. I use 98 octane for fuel. I get about 290 on long, spirited drives on the highway. I can get around 380 on more conservative highway drives. When I get about 1/8 tank of gas the motor will start chugging and stall inbetween shifts so I have to lightly pop the clutch as I drive and give it a little gas to maintain idle at stop lights... yes, it sucks. Hopefully this problem will be fixed and I'll have better fuel consumption after I put in the Tomei 276 l/hr highflow pump next weekend :rofl:

    • Turbo gods, some assistance and recommendations please I'm looking into a turbo kit for my 2.5 from MX5 Mania >>>>> https://mx5mania.com.au/products/copy-of-mx-5-nc-2-5-litre-engine-conversion-turbo-2005-2013 Power wise I would like about 200kw atw, and of course dose noises, apparently if you keep a stock 2.5 under around 200kwatw the engine and drivetrain will not hate life even when ragging on it a bit Max RPM on the 2.5 is around 6500rpm The turbo MX5 use is something around the disco potato size as  packaging room for the turbo is pretty limited, which will, I believe, give me my power goals I want and not have the turbo either under, or oversized, but the rear housing bit is confusing  It comes with either a 0.64 or 0.86 From my understanding, which so far is based off googling, so make of that what you will 0.64: spools faster = good Makes more EGT heat on boost = bad Less topend power than 0.86 = I'm only looking for 200 atw so that point may be mute????, I don't know, hence my questions  0.86: Spools a "little" slower = how much slower??? remembering 6500 is my max rpm Makes less EGT heat = good Makes a little more power up top = again, power goals is only around 200 Also, this is a street car, so there will not really be any long track sessions, in saying this I would want it so it was happy with at least 3 hot laps at Wakefield Park if the need arises  I already have a fancy pants triple pass radiator, and a oil cooler with thermostat will be getting installed as well Thanks for any information or recommendations you have 👍, and of course, the comments about me wasting money on drive in drive out modifications, or any other snide remarks about my manhood for owning a MX5 🤣    
    • Tape some wool onto the vent then take it for a drive I did this to my reverse cowl and was instantly unhappy, as anything over about 60kph would have the wool enter the engine bay, thus just adding underbonnet pressure and stooging my coolant stack, it did let alot of heat out when stationary though, which really didn't help once the car was moving, with the reverse cowl you could watch the coolant temps cheap up the faster you went on the hwy, I assume it would be alot worse doing track day speed With the vented bonnet (just after the radiator and about 1/3 up the bonnet) on my old R33 the wool on the leading edge sat at about a 45° angle as air poured out of it From looking where your vents are, and their size, I believe you should be fine at speed and air should be evacuated from the engine bay, I think it will be a night and day difference when stuck in traffic though for removing the trapped heat, and not sitting there cooking when parked up after driving around... #convection  Post wool tuft pics and data for science  This beastie is one nice and unique rig, enjoy
    • It is possible to do this stuff for "cheap". But you need to be able to get deals on all the bigger items, and it really helps if you're fully capable of doing your own work. As soon as you're paying retail for new parts, or buying "kits" because you can't fabricate necessary bits and pieces, and if you really need someone else to take the reins of doing the work because you don't have the space/time/skills/confidence to  rip deep into the car and put it back together in a working fashions.....then you pay. And these days, pay means a lot of money. You'd think things would get cheaper, but they don't. They just seem to keep getting more and more expensive.
    • It’s almost the price of an engine build, you won’t have anything to bolt onto it though 
    • Hopefully it's enough to help with the temps! I was also only shit stirring, regarding Murphy's Law basically. I've found, what ever spare parts I have, are the parts I don't break. Ever. Also have never had issues with oil/spinning bearings until I put oil pressure gauges on the car. 😛
