from what i understand japan has the same "premium unleaded" fuels, or at least similar ones to us, but the 100 ron is called "super unleaded". maybe some of the members on here who have been to japan, or live there could fill us in on a bit more info.....

I'm getting around 350kms a full tank, somethings not right.

that all depends. how many litres are you calling a full tank? what sort of driving are you doing? do you let the car warm up before driving? how long does the temp gauge come up to the middle of the gauge (normal operating temp)?

Not sure but $60 is roughly a full tank of 98, thats from almost redline empty to completely full. City driving to and from work, generally a 20km trip but it can be stop start traffic. I generally dont let it warm up for more than 30 seconds every startup but nor do i hammer it at all in the first 10 minutes. Doesn't take the temp gauge long at all maybe 5 minutes if that. My best mate who drives a S2 R33 N/A gets easily over 100km more a tank than me and he drives a bit quicker than me.

based off roughly $1.45 a litre, $60 is only about 41L, meaning you still have about 24L left in the tank (if they are like a 33 with a 65L tank), and about 10 to 15L before the fuel light comes on. at 41L and 350kms you are using approx 11.7L/100kms, which isn't too bad for city driving.

Hey,

I have a 33 gtst, i get bout 11 -12L/ 100km's

You'll use more fuel depending on how many cold starts you do too, and if it was a gtst and now gts, then you should be able to run alot more ignition timing, like fully advanced, that would help it alot, be much more lively and better on fuel, correct me if im wrong...j

but 10-12 would be the best you can get id say, and thats not that bad...

what would be wrong with that, if its the car is designed to have a turbo on it, and now it doesnt, cant it handle major advancing ???

how would that be worse than 10psi of turbo pressure thru it?? the motor is basically lacking now isnt it???

i advanced my ignition fully with the turbo and didnt even ping that i could hear, not that im saying to do that with a turbo, just saying without the turbo should be able to tune it alot more agressively..

:wacko:

yes you could run full advanced timing on a RB25DET with the turbo removed, however it will still be putting out about 40hp less than a natro motor and use more fuel as you will have to floor it everywhere to not get overtaken by an 80 year old lady in her 1970's corolla

also if you were able to run full advance on your natro without hearing any pinging then either you need to learn more about what pinging sounds like, or realise that not all pinging is audible to the human ear over the sound of the engine.

Oh you're good.... I don't have a fuel light :(

yes they all have a fuel light. it may be blown though (or there is a short in the system or issue with the sender). but they generally all come on with about 10L left in the tank, so if you are filling up with less than around 55L then you aren't getting the tank low enough for the light to come on. there are a few ways to test if the light is working. 1 is to pull the return line off the injector rail and run it into a bucket then run the car until it either runs out of fuel or the light comes on (best to do when the car is low on fuel). another would be to pull the fuel gauge sender out of the tank. yet another would be to figure out which wire in the fuel sender wiring is the one that sends the signal to the dash and short it out and see if the light comes on. or you could simply drive around with a few litres of fuel in a jerry can and just keep driving until either the light comes on or you run out of fuel.

i also have a feeling that in the 33's it doesn't come on until below the line. i don't think mine came on until it was at the top of the E

Change your spark plugs, run 95 at least, change your o2 sensor and get a pod filter which will help. Clean your AFM and maybe clean your injectors. If nothing changes i highly suggest get a SAFC it will get you extra power and much better fuel economy. I used to get 250ks a tank i got a SAFC and a tune and i got more power and was average 450-500ks a tank.

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
