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...

      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.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
