Also, don't bother saying how many KMs you get to a tank. The best way to work it out is:

1. Fill up to a full tank

2. Reset trip meter

3. Drive

4. Fill up, note how many litres it takes

5. Do this calc: Litres divided by KMs ... then times that figure by 100 = Litres per 100 KMs

The reason this is a better comparison is that one mans "empty" is different to another persons. For example, I normally get 320kms out of a tank... but I never take mine to RIGHT on the E mark, and I put 42-46L in it.... so around 13 - 14 L per 100kms, which is around normal for a mildly modified GTR IMO.

yeah thats why i said removing the restrictor makes you run 14.7 psi

not saying that is a good idea

what im saying is that the gauge is in mmHG not bar

7 mmHg = 1 bar

May i ask, where is the restrictor that you remove to get full boost?

my 32gtr is pullin 400km's for full tank. all i had done was injectors cleaned, changed air filters, o2's,

i give it a fair bit of push around suburbs.

but yer my injector is now leaking out fuel i assume this time round i wont be gettin 400k's.. what is it i need to replace .. O-rings for it? and is it hard to replace?

i just got a power fc installed + car tuned.

driving sensibly im now getting around 420 to a full tank round town.

i've been giving it a hard time this tank and it looks like it will hopefully still be around the 320 - 350 mark.

car is almost stock - 222rwkw @ 12 psi.

hope this helps.

also, check your comp - is it standard? my old cpu was the main cause of my previous poor economy (around 300 to a full tank barely hitting boost).

      Nismo copper mix twin “pull” pedal height engagement

      By soviet_merlin · Posted

      I don't how much the car makes a difference or whether it is just a question of gearbox and clutch. On mine it's fine. Pull type Nismo coppermix twin (standard, not competition) on the 5 speed in my Stagea. OEM slave cylinder. Bite point is a few cm off the very bottom of the pedal. Clutch pedal all the way down to put in gear, and when heading off at the lights, there's a tiny bit of nothing and then it starts biting. And fully engaged before the pedal is all the way released. There's a bit of play at the top where the pedal does nothing anymore. Are you in Australia @ck_chino? If you are set on using a Nismo slave cylinder I have one new-in-box at home. Ordered it together with the clutch but didn't get it fitted. We can work something out if you want it

      I am using a pull nismo coppermix twin in an r34 getrag box, had both the standard slave and  then the nismo one. Adjusted pedal to get bite point how I wanted , it is on the higher side, but would fully disengage past half way down.  I also read that the nismo slave won't work but I had no issues with the stroke, might become one later as clutch wears but 2+ years of happy motoring so far.  Take the above as one input only, specially as my setup is a bit unique in that I am using an S15 clutch master , cefiro clutch pedal, custom braided clutch line. Lots of variables at play.

      Oh for sure, I'm just recounting my thoughts 😎 I'm not what you've got there to fuzt with.... likely my first idea was on the money -- rebuild or replace connectors. You can get a lot of connector stuff here  -> https://www.rapidcables.com.au/ Didn't look in the boot of mine, because I replaced these when I renewed the pump (plastic of connectors had gone brittle) edit: what I used... https://www.efihardware.com/products/2120/Deutsch-DTM-Connector-Kit-6-Pin ...cheaper... https://www.ebay.com.au/itm/364900039138

      In no way was i suggesting it’s your fault mate. The trailer cable has a plug that I removed. I will have a closer look, but I did remove the trailer wiring cable with the tow ball as I don’t need it on my silo. i have replaced the fuel pump already there’s no need to remove the cradle again I can see the wire colours from it in.
