So after running around on five cylinders and a boxer-like rumble for a few days, the verdict came back that an injector has died, which Nissan say is an $800 fix with a month's wait to get one shipped ex Japan.

Now, I suspect that &450 for an OEM injector is a bit silly, and I could probably get either mine or a secondhand part reconditioned for much less, or a full set of new ones for slightly more. A quick yellow paging has turned up B&M Fuel Systems in Richmond, does anyone know/recommend anywhere else?

I'd think that lots of people would have standard injectors hanging around for GTST's... since they upgrade them to bigger units, but less would for NA's....

Good luck mate, that quote from Nissan is stupid, ignore it and buy local / second hand.

You will likely get a brand new set of upgraded injectors for that price! Nissan know very little about performance cars :P

I hope you're implying he should also purchase the equipment required to support upgraded injectors too :thumbsup:

OP, I'm curious as to how it was diagnosed as a faulty injector? It's pretty unusual for an injector to go like that. Have you sussed out the ignition system first to make sure it's not a coilpack/loom/spark issue?

If it's the injector, you could probably take them all out and get them reconditioned / flow tested for $200 or so.

That's what I thought too, even supported by some quick searching under 'why does my skyline sound like a boxer?', but they tested all the plugs and coil packs and they were fine, compression tested the block and still nothing, then looked at the #6 injector as the source. Took them 5 hours to figure it out apparently.

Spoke to B&M this morning, if I were smart enough/had the tools to remove it myself, it would cost $40 to recondition the dead one, or $120 for a replacement.

2+ hours of labour, they aren't the easiest things to remove / install... There's $250...

Verdict's in - $120 for a reco'd piece, or $190 for a new one with a days wait on parts. Much better than $460 and a month ex Nissan, Odium, you're right - I'm looking at a few hundred in labour.

She'll most likely be going to the farm in 12-18 months so I'm just replacing the dead one and hoping for the best. Are in-fuel injector cleaners worth using?

Aznew charge $25 I think to clean and flow test an injector. Don't bother with in-tank injector cleaners, the mesh filter in the top of the injector is most likely blocked.

If you remove the injectors, make sure you replace the orings.

So i've finally got her back, and it's not what it seems.

Injector - Fine.
Coil Pack - Fine.

The culprit? The plug into the coil was corroded to hell, and had corroded the wire into the plug away completely. Real pain, and about $800 in labour to fix.

Which brings me to my next question. Given the fact that it was misdiagnosed by nissan service, and having them repair it wouldn't have fixed the problem, and the actual cause was something that (according to B&M) should really have been picked up on if a decent look was had into it before deciding it was an injector, and subsequently not testing the injector to confirm it, how likely would I be to recoup some of the costs from nissan service, given they have a three month warranty on their work?

Yep, given I was told it was an injector issue, I had it booked to replace. Didn't find out what it was until he'd pulled it all apart and tested the injector to find there was nothing wrong with it, so then he had to reassemble the whole show to troubleshoot it from scratch.

Half the cost is in removing and refitting the injector that was apparently busted. So the dealers wrong diagnosis cost me $500, when you include their bill.

I'll take it up with them, hopefully they'll be decent about it. Only sure thing is not asking guarantee's nothing.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.

      I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
