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,

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
