fuel tank is about 65L, best to use premium fuel, but not a must. as for fuel economy, as with every car it really depends on how you drive. if you like flooring it everywhere then you will get noticably worse economy than someone who drives like a granny

yeah, hence not being fussed about replacing the O2 sensor. I just have that feeling that I should be getting a bit better efficiency from a 2.5 litre 6... But maybe im just getting more and more upset at the increasing cost ($) to do said 100km- aka fuel prices

:P

i think that if your o2 sensor was bad you'd be getting worse than 12L/100kms of "brisk city driving"

it really comes down to how you are driving. if you are flooring it a fair bit then you will get poor fuel economy, even in something like a skyline with a relatively small engine. they aren't exactly tuned to be economical either. they are tuned to be a bit sportier, so that means that even driving like a granny you would use more fuel than some other 2.5L engines out there.

i was getting much worse economy than you in my r33 gts-t. i was up around 17L/100kms. on a long trip on the higway it was down around 10 or 11/100kms. new o2 sensor made no difference because it was down to my driving style. the o2 sensor has no effect on how rich the car runs when you floor it. the ecu ignores it once you get into higher load cells on the map. this can be as low as about 40% throttle depending on rpm, etc. the o2 sensor is only used in light throttle applications, so light acceleration and cruising along at a steady speed.

before you go out and buy a new o2 sensor you would be best off just testing your current one with a multimeter to see if it is working properly.

il whack in about $50 so half a tank aprox, will last me about 250 k's, but its all driving style. i try and change around 3k rpm but its not always the case haha, and i do alot of stop start driving aswell which dosent help.

after getting the new tuned ecu in and boost controller retuned I found that i was in the 20L/100km bracket for 'very spirited' driving. New O2 sensor goes in this week...

Laid waste to an EVO so it was all worth it :3some:

also girlfriend screaming real loud and grabbing the jesus bar and the roof under full acceleration. LMFAO

Have put in the new NGK O2 sensor, sealed up the filler cap leak so now have an airtight seal on the petrol tank,

also put on a turbo-back exhaust and done a further tune and now down to 12.5L per 100km for brisk city driving.

Stoked.

Ill flush with injector cleaner and do a final tune and hopefully under 12L...

    • Yeah good luck out there! Will be good to see a mighty GTST going harder than the GTRs
    • i will be there 😁
    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
