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

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.

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.

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.

i searched the yellow pages and found nuthing under "petroject" ?

    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
    • Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.
    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
