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,

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit?

      What should I do next to hold the head on

      By Gareth87 · Posted

      Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!

      Chris' Toyota Mark ii JZX110

      I'm a fan of the JZX110, and the Aristo. Big cruiser cars, and with the factory cars, super comfortable and feel like you're driving an armchair! And the JZ motors are a pretty nice engine too, especially with some basic mods.   The import process, and the need to be able to trust people, and the fact there's so many scammers around is what ever puts me off wanting to go through that ordeal!

      I don't care for these at all, but at least the underside looks straight and not rusty. A good basis for a long life. Many cars from Japan have been lifted with forklifts and f**ked almost irrepairably.

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      Yes, but it's not dumb or dodgy. You can build a perfectly good boost controller from a pressure reg, a relief valve (looks same same as a reg if all from Norgren or SMC, for example) and a check valve. I ran one for years. Only superceded with  EBC because I could get one for cheaps and wanted finer control.   THis mod is certainly not a sketchy boost mod, provided the boost is kept below the "spin to death" threshold of the turbos.
