Awesome. I was going to change fuel filter anyways. But you recon take fuel line off from front of the fuel rail? How much petrol should I put in to flush it out?

Run through what is in the tank first. Then add a smallish amount and run that through, then repeat. No point adding good fuel to bad in a 50/50 mix and then running half of it through leaving a 50/50 mix of old and new behind.

Keep in mind though that running a tank to the bottom can and will pick up crap from the bottom of the tank, pulling it through the pump (which might not appreciate it) and definitely putting it in the fuel filter. So don't change the filter first, and be careful about how low yo run the tank. It can of course be hard to know how much fuel is actually in the tank!

Just rereading your original post and you said you connected the battery the wrong way. I would get that ECU checked to make sure you didn't fry anything inside when you through voltage up the wrong way considering your lack of spark.

Also I would pin out the coil pack loom and make sure the coils that aren't firing are actually getting power from the ECU.

so i just did a compression test..not looking so good. i dont know exactly what this means but i cant imagine it being good that a few of the cylinders have low compression.im hoping i just didnt put the gauge in properly but im fairly sure it was in properly each time but not 100% positive.didnt have time to retest them all since it was getting too dark. but i put the new spark plugs in. didnt get a chance to test the fuel side yet..of theirs any point now :/

should mention that i haven't changed oil or the oil filter yet. could this cause lower compression ? im guessing it wouldnt make a difference.

google time !!

hrrm im hoping nothing to major. im just reading a few things on google. someone said to put a tea spoon of oil into the spark plug hole of the cylinder with low compression and redo the compression test and if its higher it means the rings are worn out and if it doesnt go higher then its the valves. least thats what im getting from what im reading. i'll redo the cylinders that had low compression tomorrow in the morning.first normal then with a bit of oil in it

yeah i noticed it was the ones next to each other. would that mean head gasket was stuffed before i got it ? or just from sitting ? i;ll be pissed if thats how the guy sold it me

lol - must have been typing at the same time.

answer is yes it could be the HG between the 2 low cylinders

ah now I see GTSboy is on the case above yours

Edited by Sinista32

somewhat freaking out lol. not giving up yet. worth getting a new head gasket? should i try the oil in the spark plug hole first or not bother and get a head gasket

Head gasket is easy fix but not so much if you don't know what your doing. It's a lot of work but not a lot of cost [emoji41]

Find a decent workshop nearby and get a quote to change it for you.

yeah i dont think i would risk doing that part myself.i've seen it done years and years ago but dont want too stuff it up. i might start googling it and watching some videos and then i'll decide if im capable of doing it on my own lol i'm hoping my cousin will come down with his g/f who's an apprentice mechanic. they're both into the nissans but not sure on their skill level. cant be worse then me though lol i'll get onto him though.looking for a head gasket now. any recommendations ?

yeah i think i;ll do the oil in the spark plug test and see if it raises.if not then i;ll look into maybe getting head gasket. if it does rise after putting oil in the hole what would i be looking to do next ? throw it out ? lol

    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
