Help! 700cc JECS/Nismo style injectors???

[bc.]

I bought some used 740cc Nismo injectors off a member on here, just got them flow tested by Mr. Injector and they came back at 700cc/min, 3 bar, 100% duty cycle.

I am confused because I don't know who they were made by. Did someone really make 700cc side feeds? They do not look re-drilled and the tester said, "Patten's looked good. High volume injectors put out a lot of fuel so a fine atomization is not normally what you see. Those had good penetration and even flair. If they were drilled they did a good job because the balance was good."

Does anyone know who made 700cc injectors? They are red, identical to Nismo 740's.

I am trying to figure this out because JWT is doing a ROM tune for me and 700cc size is basically useless, I would need a retune if I have to replace an injector because I can't find this size anywhere...

HKS also makes 740cc injectors that are red. But they are 740cc. Thats what i use.

Red? Drilled out stock 270s?

We have a winner. Nismo injectors use a different coil and basket. They also have a different part number on top. Post a pic of them.

I really don't think they were drilled out, I had a magnifying glass on the holes and they look very good. I couldn't get a close up picture without blur though. Another thing is that the tester doesn't think they were drilled because they all matched so well, which is highly unusual for drilled pieces.

I did find this link though, maybe it could be these? 700cc Nissan/JECS, Phase II Fuel Injectors - SR20DE, KA24DE, VG30DE, VE30DE, VQ30DE, VH41DE, VH45DE - Import Fuel Injectors - Custom Milled High Performance Impreza WRX and Mazda RX7 Siemens Injectors - 18114700, Nissan/JECS, Phase II Fuel Injectors (http://www.fiveomotorsport.com/nissan-jecs-phase-ii-fuel-injectors) but I have never heard of the company, gonna do some research.

I didn't know that. I always thought that Tomei/HKS/Nismo 740ccs straight-drop in were made by JECS and where just rebranded. Good to know!

My Tomei 740ccs (made by Jecs) have a part number on the red plastic part. I double checked those numbers on google and they did comeback as Tomei. Look for a part number ontop and pics will help too!

I was under the impression you could not ID Nismo's from the part number. I will get pictures when I get home from work.

I don't remember all the numbers, but I do know they do not say JECS anywhere like the typical JECS injectors do.

Who cares, they good , used them

if you need 700's to perform like 740's.. uhh bump up fuel pressure.

they could be STi/Wrx injectors. they used side feeds back in the day

JWT said this could cause drivability issues because it will only match at high loads and will not match in the middle. I was thinking subie maybe as well.

I am gonna send them to JWT to have them check flow and atomization, $30. They needed to be cleaned anyway and JWT does not do that.

well if they are dirty and gunked up they could very well be 740's that are dirty and gunked up!

I've never had problems with raised fuel pressure for more CC. But I don't raise base pressure, just inboost pressure.

I've had my siemen dekas rated at 60lb @ 43psi, at 75psi without issues and bumped them up to 80+lb

I got them back cleaned by Mr. Injector. He tests, then cleans (ultrasonic bath), replaces o-rings and any broken parts, then tests again. So they have been cleaned and the tested rate was 700cc across the board exactly.

ive got a set of almost new top feed rc 1000's if you need em.... pm me if interested....

These are the injectors. The numbers are hard to read, but I think they say A46-Z00 and 0126Y24.

[jppierre]

Sorry to bump this but i have the same injecyor on a project i just bought... Is it 740cc , mine are a46-700 same as picture

[EDacIouSX]

i can take a look on mine tomorrow jppierre... mine are 750cc

but by chance does anyone have the latency for jecs 750cc injectors? ive been searching for the past 45 minutes and no luck.
