Hey people I've got a 93 GTST and I have always been sus about my fuel consumption. I drive to uni and work every day (city driving) and believe it or not I get about 550kms out of my tank sometimes even 600 if I drive granny styles, no bull !!I think it is because it has been dyno tuned, leaned out ???? I've got a cat back and a cheapo air pod, but otherwise stock (dynod at 160RKW). Any way, all my mates get 350-400kms ???? Even if I really trash it I get 400. I've never done a full tank of full highway driving but I am sure I'd get more than 600kms ? I've worked it out and I avarage about 10.8 to 10.5L/100kms. I think this is excellent, I love my car because I can actually afford to drive it!!!! LOL

Well my question is do you think this excellent fuel economy is because it has been tunned??? I bought the car with the work already done to it so I am not entirly sure what's been done???

And my other question is are Auto's worse on petrol than manuals, because I had one before my manual and I bearly got 350's !!! driving nicely !!

Cheers

my 180sx is pretty stock and i only get about 400km per tank thats pretty poor hey and like thats not even giving the car stick all the time.. but hey be reasonable you gotta give the car some poke once and a while.. but 400 km out of a tank is crapola right..

Hey Fonz,

My mate has a 95 GTS-t manual with 3" exhaust,custom manifold and larger (slightly?) turbo & around 175 rwkw, and he consisentantly gets low to mid 10l/100km around town. His car shows evidence of having a FMI on it at some stage, but it was converted back to a stock intercooler before he purchased it.

On the other hand, my 94 GTS-t auto, with 3" exhaust from turbo back,FMI and cheap air pod with 154 rwkw, was getting high 13's to mid 14's l/100km around town. But on a long trip, my car would improve and get around high 9's to low 10l/100km, whereas my mates would stay constantly in the 10's on a trip. I put this down to myself being able to use my overdrive on the trip where I dont use it around town, and he is always in 4th or 5th gear most of the time regardless of where he is.

P.S. I said I WAS getting 13-14's because my car was always idling higher than most skylines at around 1000rpm minimum, but has now been fixed and hopefully the fuel consumption should change for the better now.

Well i have 400rwhp (well there abouts) Bigger fuel pump, fuel reg and 550cc injecs and so on. City driving i get up to 300km. Long distance Hwy i can get up to 450kmh. Driving up from sydney to brisbane i went through 2 1/2 tanks of fuel. I reckon there pretty good on fuel!!! Then again when the foot goes $20 (@ approx 95c per ltr) i get 150km to the tank.

I get between 400-500 per tank for my mostly city driving. That's a rough guess haha. Hey while we are on the topic of O2 Sensors, i noticed that mine doesn't have one after the cat. Cuz i just put on a hi-flow cat and had to blank off the hole that was meant for the O2 sensor. It's an R32 GTS-t.

Cheers,

Scott

I worked out mine last night when I filled up and I got 11.99L/100km, lets say 12. Thats probably 2/3 city driving and 1/3 highway driving and certainly plenty of boosting in there. I am happy with that, I usually get about 450km to a tank before I chicken out and fill up.

I think the old "crap at the bottom of the tank" is a myth. The fuel doesn't pick up from any lower just because the fuel level is lower. So in theory it should be sucking in whatever is at the bottom of the tank whether it's full or almost empty. Whenever you fill up it would mix it all up anyway.

I've had a look in the bottom of my tank when I was changing the fuel pump and it all seems pretty clean down there. On top of that, your fuel pump has a sock, and there is a finer fuel filter in the engine bay.

I've run my Commodore out of fuel once, and my Torana 2 or 3 times and I never suffered anything adverse because of it.

What I *have* heard of happening is some cheap fuel pumps require fuel flowing through them to keep them cool or they overheat and shit themselves (eg, most or all Kia cars). So running out of fuel on these cars could kill your fuel pump very quickly.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
