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,

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...

      What brakes on R34 GTT(Europe)

      Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.

      Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?

      Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
