Newbie in skyline scene, fuel consumption guidance

Hi guys um new in skyline scene recently bought r33 gtst 1997 and its fuel consumption is too high guys I am shocked it should not be this much my car only do 250 km per tank (55litre) it's largely stock car not bigger injectors or stuff it's everything is factory , motor is in fair condition too only 140 km on the clock but I don't understand why it's too much fuel sucker . It's turbo is not in good condition that's only thing I can notice. Does each skyline sucks fuel like mine? Some guidelines please guys thanks.

It is using too much. You should be able to get around 350-400km from 55ltr for a stock gtst. I would be getting the 02 sensor checked/replaced and checking/replacing spark plugs (ngk bcpr6es) no need for fancy expensive plugs, may as well put fresh oil in just for good measure so you know its been done. If bad fuel economy persists, you will need to look further.

Clean AFM
Clean injectors
Make sure you have a fresh air filter (oiled panel/pod = nah)
Spark plugs as above (not the ones with -11, because you'll have to gap them to 0.8mm). You might have weak coil packs
What ECU? What other mods?
Check fuel tank for split hose (you would have smelt it)
Make sure handbrake or any other calipers aren't dragging (this one is pretty quick to check, you would've noticed it straight away)
How does it drive in traffic?
How heavy is your right foot?

My GT-R averaged 12-14L/100km in traffic.

As above plus measure in Litres per 100km so you're not guessing. If you are boosting a lot you can easily suck 15 litres per hundred ...best I ever got on a trip was about 10L/100 but round town 12 - 14 sounds about right.

Just book a appointment with mechanic will see how it works nd nah mate I never boost to much I just drive normally. I check break clippers as advised by you guys nd it's normal so um not dragging anyway 

thanks everyone

Hi guys um back with same issue I have replaced spark plugs nd splitfire coil packs, clean AFM but car still sucking fuel same way as it was before. In the morning I start engine just stall sometimes or it spins slowly first couple of rounds then it's goes smooth. Seems like motor has breathing difficulties but not sure what it is. People talking about AAC sensor duno where it's located or what it's job . My car has front facing plenum, front mount inter cooler other than that it's stock car r33 series 2 . Any guidance would be appropriate thanks
