ok guys,

ive had my 34 gt for about 8 months and ever since i got it ive been getting 370 km out of a full tank (at best) .

i dont have a heavy left foot and i checked the afm and the o2 sensor, both seem to be outputting as normal.

i tryed to run it on 98 prem but it just seemed to get less out of the same amount of fuel (320 - 350).

the only aftermarket addons that i know of is the exhaust ( has a silencer i belive ) - could this be the cause.

any other ideas would be of great help.

as i ask in pretty much every thread about fuel economy, HOW MANY LITRES ARE YOU PUTTING IN?

sorry but i'm sick of every person who starts a thread using "a tank" as their quantity. everyone fills their tank at different levels, and all fuel gauges read differently, so you may be getting better economy than someone who posts up saying that they can go 100kms further because you fill up with more fuel left in the tank.

put your fuel economy into a litres/100kms format and then you can see what sort of economy you are getting. anywhere between 10L/100kms and 15L/100kms is accepted as normal without knowing your specific driving style, conditions, etc.

My fairly stock R34 (just a turbo-back and pod) gets 10.14km's/L on the highway (sampled when driving from Sydney to Brisbane, in a loaded car. Probably equivalent to having 2 passengers). But around the city when I first got the thing, I was lucky to get 350-400 from a tank (55L). That's cause I was tack-tacking everywhere though. :)

i fill it to the top ( pump wont let me put any more in)

im not sure but the standard size of the tank is about 60 in a non turbo ( if it had a turbo i wouldn be worried)

*facepalm* god i hate stupid people....

saying that you "fill to the top" is totally pointless if you don't take any notice as to how many litres you are actually putting in. yes the tank holds 65L like a turbo one does, but if you are only putting in 40L when the gauge says you are out of fuel. if were to simply compare the kms you are getting before the gauge says the tank is empty and compare it to someone else then of course your economy will seem ordinary because their gauge may be more accurate than yours, however your actual economy when calculated accurately may be better than theirs.

long story short, next time you fill up take note of how many kms you did and how many litres you put in. from this you can calculate an accurate fuel economy figure to go off. the formula to use is Litres of fuel divided by kms travelled divided by 100. so if you do 370kms, and put in 40L of fuel then you would do 40/370/100 = 10.8L/100kms.

I seen it thought he was a yank for a min I agree with jez o2 sensor also work out how liters per 100 your getting. Your gauge might be on your left foot

Doesn't matter what side the wheel is on the go pedal is on the right

    • 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
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
