Ok - did the experiment, and drove for about 1/2 of my weeks use on high boost (normally only do maybe 15kms in high boost - and use low boost most of the time when cruising), and refilled after 3/4 tank. extrapolating the use, I would have gotaround 510 km from this last tank - 100km more than running on just low boost. Also, I never knew the actual tank capacity, so have been basing everything on a 60L tank.

I filled up today, so will try a whole weeks' worth of driving using only high boost...

When are transmission services usually due?

Once a year. I'd highly recommend you dont ignore it. Its as important as servicing your engine IMO. :)

Be aware some places will say they do "transmission servicing" but all they do is change the fluids. To get a proper service done, take it to an auto trans specialist. They will actually open it up and inspect it/tighten bands as needed etc. as well as changing the fluids. You get a more thorough job done if you take it to an auto transmission specialist. Average cost is about $130-150.

Since driving my new manual Stagea I've noticed my fuel efficiency has gone up from 17L/100km to 14L/100km. This is just from initial observations, but looks good :)

do you mean has gone DOWN from 17L/100KM to 14L/100km?

Sold... I'll book in MV Automatics Blackwood and get the shift kit too. :)

I think he means fuel efficiency has gone up, as opposed to fuel consumption going down

Exactly :)

I drove down to Newcastle from the Gold Coast last week and achieved 9.3k/lt or 30mpg. 460k's from 43ltrs I am pretty happy with that cruising on 110kph.
thats roughly where mine sits at :sorcerer:

jesus thats awesome economy !!!

i get 320 to the tank on my cedric

my stagea still only gets around 200km

but hopefully that will change by next weekend

Ok - I can now categorically state that high boost is NOT the most efficient setting on the highway - only got about 400km this tank, and did more hwy km's than average..... So, high boost for hills and round town (just not stop/start), and low boost for traffic jams and hwy....

Next weeks episode: I am going to change boost settings depending on road conditions, and see if I can get more than 600km out of the tank!

After now owning our S2 for six months, I have found that city driving is VERY different to going on a country run. Around the city, driving what I call "Normally" (which includes blowing the odd shithead away from the lights or stopping them cutting me off). I find I can only get about 360kms per tank. If I can go a whole tankful and not put my foot down I can get 420km, on a run at a constant 110kph, we can manage 525km.

So I wouldn't mind betting that it's the same with guys. But I didn't buy a performance wagon, just to watch how slowly the gauge goes down. I have a falcon on gas, if I want around town economy. With the Stag I really think that it is the short runs, (traffic lights and constant acceleration) that kill the economy. I am still working on that method of being able to earn money faster than I can spend it..... in this regard the Stagea hasn't helped!!

Pretty much exactly the same as you. Do you have many mods on the car?

I've also found different fuels (98ron Shell, BP, Mobil - in that order) give different mileage too.

Thats exactly the economy my series 2 gets. I earthed the boost solenoid last week, so am interested in how that affects economy. I have a theory (untested) that having higher boost coming on early will assist in moving the weight of the Stag up to cruising speeds easier, so therefore the fuel consumption my even out, or even be slightly better. I will let you know how it goes. It certainly helps the driveability, and means I dont have to sink the right foot as hard as before.

I havent done a trip in the car since getting it a year ago. I was hoping to come up for the skyline show & shine, but had to miss that in favour of the rugby test.

I would love to do a tour (if anyone is interested) from Canberra to Moss Vale & meet up with some of the Sydney guys - then drive down through macquarie pass to Wolllongong, down the coast to Nowra, then up Kangaroo Valley, back to Moss Vale then farewell each other at the highway. I will put up a separate post to see how much interest there is. There are some fantastic roads for the Stag to enjoy there.

Very interested on seeing how this goes with consumption. Keep us up to date. My only worry is that the boost will come on too early while cruising on the highway (110kms @ 2500rpm) which might be detrimental to the solenoid or something else maybe? Why else would they have done a 2 stage boost as stock?

I earthed out the boost once, just before going to the drags, only to have a really bad misfire come on. I must admit that I also put in about $20 of 95 octane, and at first thought that it might be shit petrol.

But it ended up being spark plugs. I just can't help wondering if using higher boost at lower revs had anything to do with the plugs stuffing up though. I only did one run on high boost at the drags, then pulled the wire out, but the 2nd run was just as bad. Then gave up and went home.

My car BTW doesn't have any serious mods, only an exhaust (& turbo timer!!), and to be honest I am not sure of the extent of the mod to that, as I cant get under the thing 'cos of the body kit. I'll get it up on a hoist soon!

I havent had any problems whatsoever with the solenoid mod. The car runs great, and taps into the torque a bit earlier because of the slightly higher boost. I have a split dump pipe, full 3" highflow exhaust with hi-flo Cat as the only mod. I only use Premium unleaded to refill & use Mobil 1 synthetic oil.

In relation to solenoid performance, I cant see a problem there. The solenoid is an electrical component with no moving parts, and is not likely to suffer from "wear & tear". I do ensure that I stay off the noise pedal when the Stag is cold, but that is actually easier now that boost comes on quicker.

In relation to highway performance, I would consider it an advantage. For overtaking, you have the boost in the optimum range earlier in the revs, and its not like the car is sitting on full boost at 2,500 - 2,700 revs and cruising. Only when you put the foot down does the turbo spool up a bit quicker. In any case, its not like I am getting into the unsafe/unreliable range of the ceramic turbo, as it never goes past 9psi in any case.

I am halfway through the tank, & will post up results soon.

:)

what are your gas prices like to care THAT much about every little ounce of gas mileage

I pay 143 yen a litre of gas

68 liters

and i get 350 on the cedric last tank

and i think its good!!!

the stag gets like 230 on a good day

horrilbe

but seriously, what is yalls gas prices. and how do you get upwards of 400KM a tank?

are you stock or modified alot?

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
