Hey guys i just want to find out from you guys who have the same car (and only you please) with the standard pump, how long it primes for in the morning or after many hours of not running. If you don't start the engine when the ignition switch is turned to 'ON' how long do you hear the pump prime for? Is it very loud? And lastly do you ever hear the same prime noise for a very short time (1 second) during prolonged idling? ... memory this too is only after the first start in the morning or after many hours as previously mentioned.

Many thanks,

Deren

Yeah cheers for that mate. How about the prime during idle?

BTW just realised your after a nissan boot badge, i dont think i will be using mine anymore so its yours if you take me off your bad trades lol!

The sound came on due to lack of lubrication in the fuel pump, you can either put Redline SI-1 in your petrol tank or buy some ashless motorbike 2T, added 50-100ml and it will do the trick.

Not on the GTR. I just cleaned the TB on my Mazda's KG 2.5L V6 and it ran like crap quite some time... next time I wont be lazy and I'll take the TB off rather than just spray all that carby cleaner down its neck :)

Is it a tough job? I'm sorry about dragging things off-topic, but my plan is to clean the IAC, clean the TB and then if it is still high I'll adjust the trim pot on the ECU. I'm pretty sure it had an aftermarket ECU removed prior to export, so the problem could be there...?

Dont clean the throttle bodies, It wont make it any lower, only higher, the more you clean from around the butterflies the more air gets thru when they are supposed to be closed - Hence high idle. Prolly the idle control valve getting stuck. Good place to start anyhow :laugh:

Very good point dude! Cheers

Thanks guys. Sounds like i have no problem then :)

Its not the attesa pump. There would be no need for it to operate at idle. Only works when you are locking up the clutch packs in the transfer case to provide front torque.

    • Yes, but 2 things of the top of my head, 1. Legalities of nitrous on a street car. 2. No chop chop. I fully understand that there's much cheaper ways to make power, and whilst a wet 50 shot is fairly cheap to install, bottle fills are expensive, and bottles always need to be refilled, and nitrous also has its own inherent issues with reliability, and tuning, from my experience of others using nitrous, it doesn't take alot to lunch a engine real quick if something goes slightly wrong when spraying, if I wanted a big chunk of additional powers, a spooly boy would make alot more sense, disregarding the additional engineering, supporting mods and other logistical issues of sticking a spooly boy on a car that came naturally aspirated from factory  In the end I'm not racing for sheep stations, and I don't really care if people make more power, or are faster than me, or spend less, or more than me, the only thing the car needs to do is drive around and make me smile, which it is doing now Really, I just want a shiny new intake to look at when I'm cleaning the engine bay, and of course, some more induction doorts, and maybe even that 5kw for that elusive 200hp cherry on top that I might get If the FAB9 intake plenum, TB and air filter box thing doesn't eventuate for whatever reason, Plasmaman do one, not as fancy looking, and a fair chunk of more cash is required when including the TB and other bits and pieces that are required to install it, but, it is another option that is available to me if FAB9 one does fall down (but I really, really.....really, want the FAB9 one though) TL;DR. You want what you want
    • Been so long since I have been here,seeing SDU is dead. I had that problem on my gtr in 2006 but luckily there was no engine damage,it was inspected by Hytech Engines,race bearings and extended crank collar put in and that was about it. Hopefully yours is sorted now.
    • Would it not be cheaper to just spray nitrous?
    • I've got cash, it's the NA LOLS I'm after now Plus, I've had a few boosted cars, and it is soooo easy to turn a reliable car into a unreliable drivetrain eating money pit monster by just paging up and chasing more My power goal for the NC is to try for a reliable naturally aspirated 150kw or 200hp atw (I'm old, and the old naturally aspirated cherry of 100hp per litre is a goal that I would like to hit), no more is really needed for what I use the car for,  so a additional 5kw is what I'm chasing now,  that 5kw is about $3k away, I think....
