Hey guys

I have been trying to figure out how my stagea goes with fuel.

I have done my research and seems normally they should do 400kms per 60l tank.

I drive 80kms to and from work every day so I do 400kms a week. I fill up $70 premium every Monday and lasts till Saturday. Premium price varies obviously.

Works out about $14 a day for 80kms

What's everyone else getting. Does my figures sound about right or is my stag using a lol too much fuel??

You should talk litres per hundred to be more accurate.

Mine is a rwd with rb30 bottom end. To and from work 12ks each way uses 13.3 litres per hundred. Have been meaning to tidy up cruise part of tune for a while as I think it could be better.

I'm assuming your commute to and from work contains some freeway/highway driving?? 11.25 sounds very good...You have to remember Stagea's (S2 I think...dunno if the S1 or the M35 is the same) have a 68L fuel tank in them

On the other hand - check out http://www.skylinesaustralia.com/forums/topic/167866-stagea-fuel-economy/ - There is a discussion thread on fuel economy

S2 c34 rs4s gets 400km from 3/4 tank (have never run it into the last 1/4) if I drive like a total nana with only one or two slight boost moments. 350km if driving a little more spirited. Driving on the highway between adelaide and melbourne I got 550kms approx.

(I dont know how big the tank is to do ltrs/100km) but would assume its between 13 and 16 lt/100km average. Fair heavy considering the charger (with a 4.3ltr 4bbl auto) does about 15-17 lt/100km.. and it weighs about the same lol

Is there a system available for the c34 that can do the same?

Not sure, all the searches on Japanese Yahoo auctions searches came up for M35.

There are a few guys that can do the language conversion software, and the units are worth nothing in Japan, basically throw away $40 nzd. I guess it must link info from diagnostic software/on board computer to the nav screen?

Yes, it is called ECU Talk, here is a link for it,

i have one in my car, it is useful not only for L/100km but all other diagnostics.

can be used with a laptop and consult software to check for faults.

S1 RS4V - does around 12.5-13L/100km "round town" ie Canberra roads. Country highway is 11-12L/100km, freeway is on the lower end of that.

Fuel economy improved ~1L/100km when I installed a hypergear hi flow turbo and a mv auto stage 2 shift kit.

Can't say scientifically which did what improvement, but my money would be on the turbo.

S1 rsfour, manual converted.

Only engine mods are rear resonator and big fmic.

14l/100km regardless of hwy or town driving.

Pretty much 100km per 1/4 tank or 400km/tank, I always fill up at around 350km.

ive found a noticeable change in fuel economy since having a stage 2 shift kit fitted to my S1RS4

Its possible, though I can't think why. The box runs a slightly higher line pressure, so if anything there should be more energy lost through the transmission. Perhaps not enough to make a difference on economy. MV autos said it shouldn't make a difference.

The larger turbo should be less restrictive and doesn't spool up at the whiff of a throttle. It now stays off boost unless Im giving some throttle over 3k rpm. That should be more efficient with the stock ecu.

Still, everyones results may vary. I read a post once saying that the stage 2 kit would effect the lock up converter, and I havent found that to be the case at all. Can't see how it would be either.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
