Injector O-ring Replacement?

[rhys5169]

my first injector is showing a small amount of residue stain around the fuel rail, not wet to touch but enough to give my car a potent fuel smell and leave a stain in the surrounding area....

i called nissan regarding a repalcement injector and the pricks want $360 EACH!!! i was gonna just replace the whole injector if i cant get a seal replacement/fix??

anyone know much about this or recomend a shop?

cheers

i would go aftermarket

it will be better for your car and your pocket

petroject stock them...alot cheaper

and you can check to see if they are leaking by dripping a little bit of oil around the end of the injector and listening for a sucking noise.

There is 3 rubber o rings on the injector - nissan have them and I think a complete set to do your whole 6 injectors (18 rubbers) is around $120. I would try this first unless the injector itself is cracked or something more sinister......

Dude, you're in the same situation as me!!! I had one leaking injector... then 2... then 3! They all seem to go at the same time. Had fuel stains, very strong fuel smell when you turn off the car, you get comments like "Wow it smells like you've been flogging this thing for hours!" etc etc

In my case, replacing the O ring wasn't enough as the injector's were actually cracked from old age, so I forked out nearly $2k for 6 brand new GTR injectors from Nissan.

Why? Because I don't have a aftermarket ECU to control the aftermarket ECU's, and I know you can get full sets of bigger fuel injectors for over half that price. And I really don't want to go down the road of aftermarket ECU's yet.

But yeah, replace all 6 at the same time, as they all seem to go with each other in a period of 1 - 2 months.

Got Boostworx to replace all mine. But prepare to fork out nearly $2k for 6 original brand new injectors or you can get a second hand set for a few hundred, but these are apparently hard to find now as everyone wants to get their hands on it. Or, if you have a aftermarket ECU, then anything goes really.

It's a common issues for RB26's - especially the older ones. They just get weak over time.

dealt with injectors online, very good service.

buy a cheap run about and start your modifications on the gtr, purchase Nismo injectors for peace of mind.

i'll get the injector out, prob get em all out on the weekend and take em somewhere, if it turns out to be a seal i'll get all the seals replaced, if some of em are cracked then not too sure were to go next

You could've used aftermarket injectors for a 1/3 of the price and still used your standard ECU as long as they were the same size & feed.

[Ryanrb25]

as long as they have the same latency.

booking in for my moto licence soon, postie bike will do as a daily for summer lol

[SLED]

of course.......specs obviously have to be the same to retain the factory ECU

[rhys5169]

if it comes to it and i need some new injectors, are either one of you guys able to point me in the right direction??? whats the latency of the stock gtr injectors? what would be a recomended brand/model for a stocky gtr?
