If they are really jecs injectors then they would probably be great, however you have no real way of testing.

Why dont you find someone to highflow your stock injectors once you need to get it done?

Its cheap, easy and proven not to be too bad tune wise etc.

Hi,

Yeah ... I'm really torn ..

Used ones I would not like buying since you never know if they're actually working alright.

(They're also hard to find)

New Nismos are double the $$$ ..

The seller claims his items are brand new, best would be to ask him for the model (number), so I can do

some research.

If it's too good to be true, it mostly isn't ;)

Hi ... I just got feedback .. (though just one line)

--------->

they are genuine JECS 550cc injectors. Part number A46-00

-------->

I could not find much about these on the net ...

HMMMMMMMM??!!

Ohhh ... Hi!

You aren't Stao, are you?

I was meaning to talk to you (people?) anyhow regarding this:

R33 Turbo

As for the injectors .. I would not buy any high flowed for sure, but the seller said 'New' ...

Otherwise I would not lose to much time thinking about it and just bite the bullet and buy these:

Nismo

Buy brand new injectors. I throw all mine out (800cc high flow) and replaced them with brand new set. run heaps smoother and getting 2x the amount of mileage out of the same amount of fuel.

I've had hard time figuring out the cause of my test car's roughness, it turned out to be the injectors.

JECS supply OEM parts for Nissan, most of 550cc or 800cc JECS injectors that I've seen are high flows. I've been recommended by my tuner about the new ID injectors which works extremely well. I've also used brand new Power enterprise and Nismo injectors in other test cars that worked exceptionally well too. Generic highed flow injectors are unlikely to have as much droplets per spray compare to purposely built aftermarket injectors, so personally I would buy brand new purposely built injectors.

Turbo wise, every thing you need to know about high flows, different combinations of wheels and housings, installations, tuning, trouble shooting, latest ideas, innovations and solid data of each every one of them are all in our high flow thread, Its been indexed, please have a read and feel free to post up any questions.

Hi Stao,

I will PM you after I had a read .. (I already had some reads :))

As for the injectors, so what you say is that these are possibly 'New' high flowed?

Geez .. I think they're also just delivered in a plastic bag, so probably 'origin unknown'

I really would like to save, but on the other hand having 'dodgy' injectors might be a loose end

when trying to tune your car.

And till today I always bought quality .. Tomei (pump, cams), Trust (downpipe) , HKS (boostcontroller) ... and Nistune :)

Close your eyes and pay for the Nismos. Brand new set of genuine Nismo 740cc could be had for about $750.

I got my set, still unused but I feel comfortable with knowing what they are. JECS make alot of oem parts for Nissan. Made by JECS for Nissan Motors.

Highflowing smaller flow injectors is dick shit.

I tried to look for ways to save money when modding my car. Sure I saved but no where near what I liked it to be. I bought and sold alot of generic shit which I didn't feel comfortable with. Now Ive got a nice clutch, sexy turbo, reliable injectors, reputable ECU, quality exhaust, genuine intercooler, top of the range boost controller. It cost a little more but it will go alot further.

True, it's not worth saving on these crucial parts I guess.

Just out of interest:

$750 sounds like a good deal .. what is the source for these?

Thanks!

I'll never know why people skimp on injectors, maybe because they are small parts so people don't feel like they're getting much for their dollars, but they are probably the most important modification to get right during a turbo upgrade. You'll waste a lot of dyno time trying to figure out flat spots and fuelling issues if you get it wrong.

Keep shopping around eBay and be patient...sets of 555s come up for around $450-$600 second hand all the time.

From memory some turbo Subaru's had 550cc side feed high imp injectors

No reason to think they are high flowed....well actually they are...how do you think injectors are made?

they arent cast with little holes in them, they are all drilled by the factory, so a 270cc side feed that looks like that will have them same pintle with smaller holes drilled by the factory than a 370 or a 550

The chap I bought them from was local. I paid $650 for the set if I recall correctly. Brand new in the boxes. I checked the packaging I got from him and he bought them for more from some performance place in QLD, I can't remember the name(a while ago now) it was sunny something or sun something performance something or rather. They are up and queensland. With these injectors and alot of boost, I get about 45 - 55% injector duty, so alot of headroom.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
