Jecs Injectors?

The standard injectors in many Skylines are JECS.

So what that ad means is someone has taken a set of standard R33GTST injectors and had them high flowed by someone.

So the questions you need to ask is not "how good are JECS injectors", but "how good is the high flow job?"

:blink: cheers ;)

I was watching these injectors too....

I thought its way too steep. You can get a set of side flow s15 injectors for about $400 from a wreaker... A set of 6 i mean...

Be carefull with S15 SR20DET injectors, the Australian spec S15 injectors are 370 cc's, same as RB25DET injectors. What you need are 444cc injectors from a JDM manual (not auto).

;) cheers :)

are these any good? Can anyone say? I'm interested.

I don't know why you are bothering;

$US429 + $US13 for freight = $US442 = $A590 + 10% GST = $A650.

You can buy brand new Sard 63508's for $A686 from Nengun.

:P cheers :D

but those need collars which require around another $300

I priced it and it worked out to be $900 all up. If I was going to spend $900, I'd get a set of nismos that bolt straigh in.

I contacted nengun and they didn't really have any idea if those sards would go straight in and just directed me to the collars.

And its risky, cause nengun doesn't have a returns policy..

SK, can you guarantee me that those will install into a R33 S2 without the need for collars?

If so, I would order them.

The problem is there are a number of cars that use the same basic injector design, 1JZ 2JZ VG30 SR20 RB25 etc. Nismo obviously use the Nissan style, but the other manufacturers seem to prefer the Toyota style. Probably for volume reasons and the shear size of the US market for Toyota injectors.

That's why for the last 2 X RB25's we have done, I used S15 JDM manual injectors. At 444 cc's they handle as much as I would want out of a standard internals RB25. Once you start paying for engine rebuilds with forged components a couple of hundy$ for collars gets lost in the rounding.

;) cheers :)

but wouldn't nismo injectors need replacing O rings to fit though ?

that's what i heard.

is this true ?

Only if your current O rings are damaged, or too hard from age and heat to seal properly. In which case they should be replaced anyway.

:) cheers ;)

Hi,

I saw this post and thought I would make myself available to answer any questions you all might have. IMO, Sydneykid hit the nail on the head... "how good is the high flow job" There are alot of companies out there that put out a product without any R&D, beta testing or quality assurance. I believe my processes and QA are industry leading. Every injector is flow tested, coil tested and matched to within a 3% variance. Plus an injector report is included with each set that shows you exactly what YOUR specific injectors flowed. The injectors are scribed with unique numbers matching them to the report.

Tang0 on this boad was one of the first people on here to use my injectors and I believe he was very happy...

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
