Economy.

I Ford meteor 84 gets 170 kms off 20litres, my r30 (l2.4e) skyline is lucky to get 100kms of the 20L. That pretty piss weak, how about everyone else? What is the problem. Ive been nursing her as well? surly its not that bad, although it may need a tune as it idles at 1k.

High idle will affect your economy a lot if you do a lot of stop-start traffic. Try getting it down below 800. Other than that, just do the usual stuff - replace plugs, clean injectors, etc. Does the R30 use an AFM? If so try cleaning it with some electrical contact cleaner.

[SuperGimp]

aFM?

[JimX]

Air Flow Meter. It sits behind your air filter if it exists at all. The ECU uses it to measure the incoming air and adjust the fuel mixture accordingly.

[SuperGimp]

oh yeah theres an intake pipe leading to a box with the airfliter, as it passes thru the filter its under that.

I know the 2.4E is a juice guzzler, probably just needs a general tune up.

Aftern owning a sr20de silvia for 3 years and getting around 450ks from 45L of fuel it was a big shock how much fuel my r33 uses. The best figures i have gotten are 11L/100ks on highway driving. I average 13.5L/100k in the city but have had it as high as 18L/100ks after a night of hard driving. I guess a relativly heavy car and a 6cyl turbo doesnt help with fuel consumption.

The best ive ever got from my R30 was something over 400kms out of a full tank. Prettymuch i trash it everywhere, so i dont think thats too bad.

Things that i have done are, new plugs, leads, rotor button and distributor cap.

Other things that will help are cleaning the injectors (one of the best things is to put a bout 250mls of Auto-Trans fluid in the tank next time you fill it up), between doing this and replacing the fuel filter it will make a big diference.

The other thing that everyone with a L24E in a R30 should do is to cut the airbox.

I removed the shitty restrictive cold air feed piece of crap and cut a big hole in the top of the airbox, ill post pics soon.

This made a big diference in power, its much quicker, revs smoother and sounds totaly nuts. I couldnt beleive the diference it made. with the standard exhaust still in place i (Quiet out the back) i have had people ask me if its a V8, others are convinced there is a hole in my exhaust! dickheads.

seriously try going for a drive, just take the airbox lid off and go for a quik spin, youll know what im talking about.

[SuperGimp]

going for a spin now /w out airbox lid.

[SuperGimp]

oh man i love you that sounds awsome. Although I have experienced another problem wif 2nd gear this is with cap to. Ok I accelerate fast in first to about 4 - 5k rpm, then i change to 2nd and put my foot down........................ LAg WTf?!? it like does nothing doesnt rev or no power, a dead spot for about half to 1 sec, insanley gay. i have new distrbtor cap, leads, plugs, fuel filter oil filter and this gay thing happens what to do????

[MicksR30]

Is yours an auto?

[SuperGimp]

no, manual.

[Jetdat]

i just wanted to say that after installing the standard muffler back in (not by choice of course) and taking the HKS item out the fuel consumption increased....

god bless aftermarket exhausts.

[Craved]

ive noticed since installing new plugs, NGK iridium's and changed oil to the new mobile 1 - super synth and ive actually lost 50-70Km's per tank!!! not sure what going on here! will the wrong gap affect fuel consumption?

will try normal mobile 1 next and see if i get it back!

[Jetdat]

Craved

wrong gap will effect consumption.

[Craved]

thanks Jetdat, i'll try the other oil first (less work) then make sure they are 0.8mm!!

cheers

[Jetdat]

no worries mate.. good luck and keep us posted on the result.

[CHRISR32GTST]

My R32 gets 400-450 with a mix of city and freeway driving

[Craved]

yeah i used to get atleast 450Km out of it, but now about 350 - 380 Km's even with highway driving, so i'll check it out!!

noticed alot more noise in the engine since the super synth mobil 1 went in, so see how this affects the sitution before regapping, as fuel consumption was (i think) ok before the oil change!!

[Jimbo2000]

my 33 idles at around 1000 is that bad?.

its well tuned with a Power FC so i'm guessing that its alright or it would have been changed in tuning right?
