Yeah but with SAFC & PFC you can lean out the fuel, so expect better figures. Don't forget that Jap imports run very rich, partly due to the crap quality fuel we get here, thus the ecu being out of sync. New O2 sensor and fuel injector cleaner works wonders too.

hey, first post here. Long time lurker i guess :huh:

Iv been considering going the R33 GTST route for some months now, there is simply no other cars which suit my criteria, and are designed to fit people over 6ft tall (try sitting in most coupes). But, i do alot of highway KM's (600+ per week), and are wondering how you guys find fuel consumption. I know there is a sticky on this subject, but its mostly on semi-modified skylines getting 300rwkw etc.

How do you find the stock manuals, for mostly highway driving? Is it possible to get over 500k's from the 50L tank when driven conservatively?

If the fuel consumption is high, try replacing the oxygen sensor. The factory sensors are Bosch, but these tend to clog up after a few years, so I have found NGK ones to be better. Part number is O2A395-E2 for R33 GTS-t.

Bumping this for potential buyers.

I ended up picking up a nice auto s2. And so far it has been averaging around 9-10 on the highway, and 12-13 around town. And i rarely drive it sensible. I really don't know why you guys were getting so low k's. This is stock currently, i'd like to modify it, but i would prefer not to mess with the fuel consumption currently :D

im at 260-270kms with my mods cause of no aftermarket EMU.

no aftermarket EMU lol

i'm getting really sh#t fuel consumption atm - 220km per tank. but i'm getting a remap soon, so hopefully i'll be able to improve that

I get around 350kms off around 42-43L and thats a range of driving....turn boost right down all the time to save fuel....but i jsut cant do it.....i have good intentions tho...

For all those people complaining about shit fuel economy.. this is how to work it out...

1) DO NOT trust your fuel gauge

If i followed my fuel gauge id be in here crying about my economy too...

ok.. here we go

Fill you tank completely

drive drive drive... after 200Ks refill all the way to the top

now divide the amount of litres you put in (lets say 29.56L) by your ks (200kms) = 14.78L per 100kms

According to my fuel gauge my car is empty after 300ks.. however i am currently using 14.4L/100kms

which means id be able to travel at least 450ks before my tank is bone dry

The tank is 65L not 60

serious? always thought it was 60 max..

i swear i filled up once to 59L or so, and it started to over fill.. thats from right from the bottom of the tank, and i could feel the car stravin of fuel, beofre i got to the pump..

hmmm

And dont buy a skyline if you constantly thinkin about fuel prices..

Get a small 2l corolla that will do 600 plus..

first in 5th, cruising freeway im spooled by 90kph and amd roughly on 3000-3200 rpm @ 110kph. if I steady cruise @ 80kph which is just the underside of spooled and I didnt come across any hills of consequence I could probably get a fair bit considering my car still has a 9:1 comp ratio.

I get the 300k's 3/4 tank of gas. I tend to start looking for a station around that bottom quarter mark. I like a healthy 'cooled' fuel pump.

second my car holds 1/8th a tank of gas in its return line so if I give it the loud pedal an the fuel pump goes into high mode its circulates a crap load of fuel around the car.

once I get proper management sorted an tuned (pfc - in the next month) il let you know how much it chews.

my old r33 gtst, I used for work got 10L/100kms without issue (city).

I only dump in as much fuel as I need for a day or two and run it down to almost empty. 20L of fuel as opposed to 60L means you are almost 40kg less weight to start with.Less weight means better ecconomy and as a plus better power to weight for a moment of spirited driving. It also ensures a cleaner fuel system, with less built up crap in your tank.

Ensuring a good state of tune and service is important too.

i am currently getting around 340kms out of a near full tank from my modified R33 GTST - car seems to be running a little rich though as their is a strong fuel smell behind my car and the ocasional backfire ;D

    • OK, Step 3, if you need to remove the valve body, either to replace it, the TCM, or to do a more complete drain.  First, you need to disconnect the TCM input wires, they are about half way up the transmission on the drivers side. One plug and the wires are out of the way, but there is also a spring clip that stops the socket from sliding back into the transmission. On my car the spring clip was easy to get, but the socket was really stuck in the o-ring of the transmission housing and took some.....persuasion. You can see both the plug to remove (first) and the spring clip (second) in this pic Incidentally, right next to the plug, you can see where the casting has allowance for a dispstick/filler which Nissan decided not to provide. there is a cap held on with a 6mm head bolt that you can remove to overfill it (AMS recommend a 1.5l overfill). Final step before the big mess, remove the speed sensor that is clipped to the valve body at the rear of the box.  Then removal of the Valve Body. For this the USDM Q50 workshop manual has a critical diagram: There are a billion bolts visible. Almost all of them do not need to be removed, just the 14 shown on the diagram. Even so, I both removed one extra, and didn't check which length bolt came from which location (more on that later....). Again it is worth undoing the 4 corners first, but leaving them a couple of turns in to hold the unit up....gravity is not your friend here and trans oil will be going everywhere. Once the corners are loose but still in remove all the other 10 bolts, then hold the valve body up with 1 hand while removing the final 4. Then, everything just comes free easily, or like in my case you start swearing because that plug is stuck in the casing. Done, the valve body and TCM are out
    • OK, so if you are either going for the bigger fluid change or are changing the valve body which includes the Transmission Control Module (TCM), first you should have both a new gasket 31397-1XJ0A and a torque wrench that can work down to 8Nm (very low, probably a 1/4 drive one). You can probably get by without either, but I really didn't want to pull it all apart together due to a leak. First, you now need that big oil pan. The transmission pan is 450 long x 350 wide, and it will probably leak on all sides, so get ready for a mess. There are 24x 6mm headed bolts holding the pan on. I undid the 2 rear corners, then screwed those bolts back in a couple of turns to let the pan go low at that end, then removed all the middle bolts on each side. Then, undo the front corner bolts slowly while holding the pan up, and 80% of the fluid will head out the rear. From there, remove the remaining bolts and the pan is off. You can see it is still dripping oil absolutely everywhere...it dripped all night.... I got another couple of litres when I removed the pan, and then another few when I removed the valve body - all up another 4l on top of the 3 already dropped in step 1.
    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
