Injection perfection (bankstown airport) seem to have a good rep. They quoted me $33 an injector, being cleaned in a bath, and then thru 1 of the pulsing machines. $33 seems abit steep?

Another place at lidcombe (search thru posts abotu cleaning) said $22 an injector.

Let me know how it goes. Im looking to do the same, though just waiting til i decide if im going to clean these, or replace with higher feed unit.

Thats like $190....???? I hope that includes flow testing and new o-rings etc. Ill try them on Monday.

Its strange the things that stick in your mind, i thought $8 (aprox) for ultrasonic cleaning was close to the mark, so maybe $33 is for flow testing and new o-rings etc?

I had mine done by Jamie Waterhouse (4721 7227) at peach tree... he did my whole 100,000km service (I supplyed the timing belt though) and I think it cost about $600 all up. Have the recipts somewhere but he has always met (or been VERY close to) his quotes and has also done a good job.

He once had my car for two days (Friday Arvo, Saturday and Sunday morning) looking for a problem with a miss... he eventually didn't find anything after spending most of the weekend on it (he usually only does half Saturday) and when he gave it back he said... I could not find the problem... (Pressure tested and flow tested and all sorts of things... even had the fuel pump out) when asked how much I owed him for his time he said "nothing... he didn't fix a thing."

I noticed that I got a much more smooth power delivery and it felt to me like I got a power gain. I had the injectors removed when they were cleaned.

I have also heard good reports about Nepean EFI and they are just off Batt street I think?

Yeah , I see your point Ben.

Flow and pattern testing , as I understand it means: Pressurize each injector, activate it, measure the flow (in cc's) and pattern (like does it dribble or is a nice spray) [yeak OK that is not a very technical explanation]

Cleaning is seperate -

No point cleaning a stuffed injector !

It included new O-rings and Plastic tips (whatever they are called) and were ultrasonically cleaned, and flow tested as well as checking the spray pattern.

Let me check the receipt when i get home for the name, i only know it as the blue building near the gym

As for differences in driving, ill never know, they are GTR injectors going into my Rb20, along with a new turbo and ECU. So was more a peace of mind thing for the new setup

Roy,

Did you get the results for each test on each injector - like on paper ?? Or did they just say 'yeah they are ok'

If the former, can you let me know where you got them done ??

I need to test 6 Hi Flow pieces of shit injectors - prolly they are still stock which would explain my smallish engine issue.... Anyway that's another story....

Thanks mate,

    • Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.
    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
