hey guys, just some information for you if you are intertested...

i have upgraded my injectors to NISMO 555cc. in the process i reused the old seals....silly idea

unfortuently nismo dont supply new seals which is a bit shithouse if you ask me...anyway

there is a seal kit you can get from repco that is made by aca injector tech http://www.aca-auto.com.au/

IRK178 is the part no. you are looking for...$22 from repco...

however my problem was it was a sunday, i had fuel pissing in cylinder 3 and i wanted it fixed NOW!!!!

so i found out that repco had part number S5000 from the same company in stock...little green o-rings perfect for the lower seals in my RB25DET (as these were the ones leaking)

now its a much tighter fit but i just sprayed WD40 in the fuel rail and on the o-rings (i used the old top rings as they dont take much stress)

i used the caps to slowly press the injectors in...

One other major sugestion for injector upgrades is to use the Champion M5 16mm long bolts with hex heads...the reason is the shitty phillips head screws that are stock on the injector rail, they are so easy to strip the heads out of... i used new stainless steel spring washers too...much better solution long term...

so now finally my horrible idle and back fireing is fixed...cylinder 3 is running just fine and my car has extra power....!!!

they way it should be...

if you have questions please ask...

Which seals are you talking about? If its the ruber seal between the fuel rail and the injector then my nismo 600cc injectors came with those...

Mate, we are talking bout side feed injectors and not top feed ones like you have. Different arrangement with the o-rings.

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
