I did took it to a mechanic 1 month ago and said the same thing, they said theres nothing wrong with it even using the computer it indicated theres nothing weird at all. I am only aware this car only has spiltfire coils, K&N air filter, turbo timer as i got this car only last year.

Must be my driving i suppose.

Is the place to measure the boost leak in front of the driver near the oil filter that is covered by a small black tip to put a gauge in?

If so the mechanic also measure it with his gauge and it indicated no leaks at all.

3000rpm really shouldn't be causeing issues, especially in a 34. General driving I've found my 33 GTST is most fuel economical driving at 3000-3500rpm marks. My Bluebird is similar story and has no issues going well above the 3000rpm mark both cars have 20yr old never rebuilt engines in them. Odd with the fuel smell etc, my 33 is always fuelie but is in desperate need of a tune. Possibly might not hurt to take it to another mechanic just for the sake of a second opinion.

@ Anfanee: Well i don't really know cause i just got this car last year and it came with it, but i cleaned it 1 month ago using K&N oil filter cleaning kit and it looks how it suppose to.

I'm going to do a full service soon as it going to hit the 97 000 km mark soon so i'm going to pray its going to feel smooth when i first got this car :)

Rev it hard.

If it blows up it was a shit engine and you didnt want it anyway , unless you do want a shit engine, which would be weird. (But make sense at the same time as this thread is weird)

the biggest problem is you have an oil filter, it restricts the engine and makes it less fuel efficient around the 3300rpm mark

take that pesky thing off and let it free flow, you will gain around 4L of fuel around 100km and increase of around 30whp

#@Elegant Skyline

It will not break the car reving it past 3000rpm when taking off from the lights to keep up with traffic.

So don't worry about that honestly, these engines have had farrrr worse treatment and have been able to handle it.

If you are looking for better fuel economy then maybe start with how much you are currently using.

How many Km would you get from 50L or fuel and we can tell you if it's bad or just a normal skyline.

Then you can start crossing things off the list below and try improve it.

Clean your AFM

Replace your O2 sensor

Check for boost leaks

These are just to name a few things to start with.

If you don't understand what the above are then I suggest doing a search in google or taking the car to a mechanic to get them done.

Cheers

    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
