hey guys. im looking for a good place to get my injectors cleaned and have the o-ring replaced. i heard that dwight (brisbane) is the man to see (well talk to for me) but before i go down that ally, im wondering if there are any places that you all recommend? i heard that "az new" were good, but there is the case that 3 of the possible 3 that got their injectors serviced there now have misfires. if this is the case are there any others in the melbourne area? or is "az new" still good, and safe to get injectors cleaned there? all help welcome. kindest regards. rod.
LOL, you cant actually beleive there is a correlation between misfires etc etc ?? AZNEW are as good as anywhere else for injector cleaning. I had MY TT injectors cleaned there as well as probably 15 or 16 other sets and they are perfect as have 1000's of other people. Re misfiring, you assume everyone can put a z32 back together properly? Also that a Misfire is just injectors when it can be any number of other things. Just take the bastards to AZNEW who are local and get on with life they will be fine
If I knew 3 people that all had problems that could be fuel related, after they took that part to get serviced I would be looking elsewhere. Also he didn't state that is was Z32's that got thier injectors done there. Tekky has obviously had good results but still, 3 other people that you know of having problems is a very large number
Pull the rail yourself and take the injectors to any decent EFI shop, injectors are injectors for the most part when it comes to servicing them. The majority of EFI shops would of seen a million types of injectors, then when you reassemble you can make sure its done right. It would cost a shit load to get your fuel system reassembled by a EFI shop, especailly if they're unfamilar with the car. It's much better to just give them a box of injectors and say "do these"! lol
well i gathered their might have been. mikez32 and i were talking about it and he said that a couple more zeds that had their injectors cleaned there had lead to getting misfires... i put two and two together. i get you had happy times with yours, as you know the zed inside out, but for those that dont, i may develop a misfire. and i dont want to have to pull the shit apart again. im sure mike knew what he was doing when he put it back together, it was in actual fact he that mentioned that it may be aznew. so i will get on with life when it back and i know its not going to be misfiring. exactly. after the plenum pull, they all got their injectors cleaned at aznew. all developing misfires. so what would you do? question them im sure.. however anton they were all zeds.. yeah have done mate. the fuel rails and injectors are out of the zed, waiting in a box, ready to go after i get some more help. i was considering dwight in brisbane as zedcare had mentioned he was great, but i dont really want to post these up. so i wondered would i get a misfire to.. obviously some have, tekky has good feedback. so im guessing aznew is the way to go. but i'll hit up a local EFI shop before hand and ask them if they will do these haha. thanks guys. kindest regards. rod.
My point is. All those guys had their cars in 1000 pces. All of a SUDDEN its "THE INJECTORS" !!! WTF, what about the connectors, coil packs, vac pipes, EGR AIV's etc or any of the 100 other things that have been disturbed or removed They all changed or removed heaps more than just "The injectors". If that is conclusive evidence I give up. LMAO :bash:
yeah true. im sure my zed wont start on the day guess your close though haha !! from what i heard, i gathered, made sense. thanks for clearing it up though. will get them cleaned at aznew. although do aznew have the o rings i need, or will i need to source them myself, as i have no idea when it comes time to install them? kindest regards. rod.
You actually take the entire fuel rail down there with the injectors still in it. They will give the entire assembly back cleaned and with new Orings. Its flow tested in your rail after they have cleaned it and put new orings on it.
I believe I have used this guy before too and he was excellent, he had a mobile van and did everything on the spot. (Cant remember the company name). I serviced my entire fuel system in a morning due to him being able to do that, as while I was prepping everything ready to re-install my injectors were done and I didn't have to go anywhere. He's a kiwi bloke if I remember correctly.
Some injector issues have come by after injector servicing when they were done ON THE CAR! The on-car quick jobs use some pretty lively solvents and detergets that dont discriminate between the fuel system parts they travel thru. A lot of stuff can be dislodged AFTER where the fuel filter lives and a certain percentage of that rubbish makes its way into the filter baskets in the injectors and can partially clog them up.You can guess the rest. Injectors that are cleaned OFF the car by a reputable outfit will have the filters changed as a matter of course. Remeber, you CANNOT dissasemble injectors! So, the injectors are not "reconditiond/serviced/ refurbished or whatever other spin they like to puke up in the ads. They are just cleaned. They simply check the coil resistance with a multimeter, connect up 12v, poke some fuel thru them at 3 bar for one minute, have a look at the spray pattern and see if they deliver the same CC of fuel each in a minute and that the impedance is within tolerance. They should also be checked for leakdown. Theres a specified rate of leakage over *blah* time that is allowable. If the check out OK they have some of those funky cleaning agents forced thru them back and forward and then given a bath in an ultrsonic cleaner no more scientific than something you can buy cheaply to clean jewelery at home then flushed out again. Lastly, the pintle caps get changed, the filter baskets get changed (if they are fair dinkum and removed them in the first place) and they add a couple of new O-rings which should be fuel resistant. Thats it kiddies! Nothing you cannot do at home if you can be bothered with a little time and patience and a couple of bucks for an accurate measuring beaker thingo and a small ultra-sonic cleaner.

I mailed my injectors to Dwight and they were returned clean in around a week, great guy and great service. I prefer dealing with someone that has a few Z user references, so definately can recommend. One note, after you get them cleaned, don't let them just sit on your bench at home for a few weeks, try to get them in the car as quickly as possible. I've heard some stories where the cleaning material can clog up the injectors if they aren't used within a short period of time(not sure how true this is) I believe I also purchased some new connectors from him at the same time, not exact matches for the Nissan plugs but close enough.

thanks evan. if you had of posted that last week i would have tried to do it myself.. but at the moment they are down at az new getting magically cleaned.. its funny how much shit they spin, but you know deep down none of it happens. yeah i heard dwight was good. zedcare used him alot and recommended him greatly, however i need the injectors quickly, so i can get the zed on the road quickly! i prob would have used dwight if it wasnt for tekky. however i already had the new oem connectors waiting so it was a matter of finding a good place.. and its all good. as soon as the rail returns the engine build begins haha. kindest regards. rod.
make sure you grind the tags off the back of the injectors before you put the rail back in. May save you a lot of time later if you havent got Nissan replacement injector plugs. You can use generic plugs then.
what the zed or my cash ? haha. hey? as on the injector connectors or the injectors themselves ? i brought the oem connectors wired from caz, but if this isnt what your talking about you have me stumped. i heard with the bosche quick release you had to grind so they would fit, but are we on a totally different wave here?
