I have not seen one website that sells them that dont have IDs data quoted or mention the injector dynamics name. Its funny to me, why cannot they build their own reputation...
Deka is not one specifically I have looked into doing this, and they may very well be great, like I said it would be hard to make a crappy ev14 as the injector is such a great platform to start with!

I also think that it is border line overkill the extensive dynamic matching ID does, and I think most other injector manufuractures do too (so they dont do it) but it is nice to know that every ID injector is broken in, dynamically tested and batched together.

It is hard to imagine that that a large injector would provide anything but a rich idle but thats where the reading on injector dynamics website would come in handy.


The ways I mentioned.....
You have a desire for wine on a beer budget. I do suggest a new narrow band, and that could actually take care of things :fingers crossed: but if it does not your either going to need to live with the issue or step up the game with better components.

There is a reason people pay over $200 an hour for tuning on a dyno and its not about squeezing every last hp out of the engine, it is so every issue like this is at least trouble shot and if possible corrected. When something like this is encountered (by me at least) when tuning I can explain what the problem is and back it up with data, and usually fix it or make it better. I have grown to not like any large injector that is not premium although sub 700cc injectors usually are good as long as the brand is at least reputable.

I have grown to dislike cars with 5-0 injectors and refuse to tune cars with deatchwerks. If they are a good denso or jecs 700 and up injector Its possible the idle wont be "perfect"
should I down size injectors? I don't plan on more than 400whp max...

There are many things you should consider changing before injectors. Those nismos you have should be able to do their job properly with the right tuner.

I would appreciate it if you answered this question directly. I'm teetering between 500cc injectors and 700cc injectors. Looking for >300whp on a KA24DE. I don't want to have a rich idle.

You DO know the injector flow is its maximum flow and not what it is flowing all the time, do you ?

Even with 1000cc you will still have a normal idle, if the tuner does its work correctly ... EV14 1000ccs have a latency time of 830µs, that should be less than nismo/sard/younameit 700cc injectors ...

Exactly. Not all injectors are created equal. Its not correct in the least to recommend someone go down on injector size in order to avoid rich or lean idles because of their lag, when the lag is what the problem not the size.

If someone is having trouble with cheap 800cc injectors they may (most defenatially will) benefit with going with ID1000s. Not all ev14s are created equal either. Many people jumpped on IDs success and use the good ev14 injector but do not do their part correctly with the nozzles.

Also, were not comparing apples to apples in your case Frank. The op has a 6cyl and you have a 4cyl. If you have a 6 cyl and a 4 cyl that make the same amount of power you can get away with a smaller injector on the 6 cyl because you have 2 more injectors. If a 6 cly is running size X injector and making the amount of power as you want, size X might not be large enough for you.



Im not a dealer of ID injectors, Although I can get other injectors at wholesale prices, some pretty decent ones for some pretty good prices. I choose to pay full retail for ID's and choose to recommend people buy them as well. id1ks are almost surely not going to be too large for anyone's engine and have unmatched tuneability. Not to mention its easier on your injectors the lower the duty cycles you run.

Zilvia is full of people that will give you their opinions on injectors if you dont like mine. If I had to recommend anything other than IDs it would be msd top feeds UP TO 72lb/hr (756cc). If an engine was less than 500cc/cyl the msd 72s would start to become a problem.

ID does make some wonderful injectors, they've worked great on the Sloppy stuff we've turbo'd.



FWIW: The Deka 60 lbers are also known as Seimens 60 lbers, just a newer EV6. They work pretty well, as do their 80lb equivelents.

I was under the impression that higher volume injectors also put out more fuel at TTPmin. Not sure why I thought this, sorry!

That is why tuners rescale all TP values when changing injectors (TTPmin and max included).
