my Nur had Nismo injectors before i changed, they were fine for 350'ish rwkw, running 2530's.

Proven, solid injector. I'm in Melb as well. I'm sure i can help you out with a good price just to get you passed these injector issues :)

I tryed to pm you but it won't work just keeps giving me an error message. Don't know what's up. Are the nismo injectors going to fit in my 32. And are they the same cc because I can't tune yet haven't got power fc.

Hey guys I purchased a power fc and controller and second hand denso 550cc injectors

I was just wondering if I can put the injectors in now without the power fc because all the workshops are closing up for chrissy. Will it still run ok or should I wait till power fc gets installed and tuned? Thanks guys

You can setup the injectors in the PowerFC, but you'll need to know the latency of the denso 550s or the idle & low throttle fuelling will be off. Also, you'd be taking a bit of a gamble on the motor if you drive it hard before getting the tune checked after the injector swap.

I would be getting any S/H injectors flow tested before fitting them, injectors sometimes don't like being removed from a fuel system and left on a shelf for a few months. Were they stored in a sealed bag or similar at least?

One slightly blocked injector can really ruin your day... I hope you got them cheap as new injector prices are dropping fast.

Yer the guy took em out of his car cloth baged em bubble warped and boxed and express posted them hense why I was thinking of putting them in the car straight away. I can't get the car booked in till the 6th of jan so I wasn't sure if the injectors will be ok sitting till then or is there a good way to store them ?

Not really, just keep them in a sealed sandwich bag or similar. I would replace the 'O'rings too if they have any sign of damage, and lube them up well before installing them, you don't want petrol leaking over a hot engine.

I use a little silicone spray to lube the Orings..

ok so injectors in power fc in tuned and dyno'd came back with 245kw on 14psi

feels much nicer to drive has realy changed how the boost comes on its a bit more punchy,

im thinking i might need some more mods soon tho to gain a bit more power 300kw would be nice i think :)

All you need is 22psi crammed down it's throat, as long as the fuel system can keep up. Seems to be making good power for the low boost you are running atm.

Having some problems at the moment guys hoping some one can help, I was driving home this arvo and stopped got fuel, drove like 10ks car started spluttering losing power for a second then come good, keep driving same thing splutter a bit then come good. Then I'm doing 80 up hill and it just keeps dropping power and I pull over off the road and it just stalls started up again stall, start up again keep driving not too bud a couple of little splutters then get to the end of the street turn the corner and stall in the middle of the road got it home but worried what it may be dirty fuel pick up from when I fueled up, coils, afm

Any help would be muchos appreciated

Well lets go through process of elimination.

Car drives good -> Stop -> Fill up -> drive off -> car is shit

In conclusion, all evidence points to the variable that you exposed yourself to, the fuel. Therefor empty tank with syphon, go to good petrol station, put in fuel and see if that was the problem.

Well I filled with bp ultimate as I usually do, the fuel light wasn't on its not like the tank was bone dry picking up all the shit at the bottom. And I'd have thought it would caugh and fart within a few minuets of driving if it was bad fuel or shit from bottom of the tank. It used to have a little bit of a loss of power moment before I got the injectors and the ecu done but my mechanic said that looked to be a faulty relay for the fuel pump and they replaced it.

if your car was driving 100% before you filled up.

I dont see how something coincidentally broke at that exact moment unless you mistook your engine bay as the fuel tank.

Also, when you fill up, it sloshes around and mixes together. Its not a layering system

running a tank dead dry will not allow the pump to pick up dirt lol where do you think the sock sits that picks up the fuel? I can tell you now it aint at the top of the tank or you would never drive long enough to see the gauge drop

Take the car back to the dyno if it can be driven and get it on there to see what its doing. Sitting behind the laptop is not going to sort it out any time soon. You have said ages ago that the car used to splutter and stall and clearly the mods now done to the car have not changed anything so there is something else that needs attention

Who tuned it?

With regard to turbo upgrades, take a look into the new Precision Turbo GTR replacements. From what i have seen they should be good for some pretty decent power. Just run them at low boost ;)

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
