As i mentioned elsewhere, of you will be purchasing new rails than i would def suggest going with the FFE rails. They are VERY well made, look great, and fitment is always spot on.

I think the Bosch EV14's are a better option since they use the same technology and are much cheaper.

I also suggest going with 550-650CC primaries if you are running a PowerFC. The powerFC can only tune down to 1.8Ms....which means anything larger than 650CC primary injectors will have a rich idle. Just MO.

They are cheaper, but the problem comes in how the injectors are modified to increase their flow. I remember seeing a specific thread on this subject that basically ended in favor of the ID's when it comes to spray pattern, dwell times, and overall atomization. Think about it, how many OEM manufacturers come out with +550cc injectors? Modification for the increased flow WILL happen, it's just a matter of how and what you might be sacrificing for that extra flow.

Previously I ran EV14s that were modified by another company. I decided to get rid of those injectors within 1,500 miles just so I'd have peace of mind with ID's.

I am running bosch EV14's with no problems. I am running 650CC primary and 2000CC secondary sizes. ($411/shipped for all of it them + pigtails and flow matching).


I dunno.

If you can get enough cc/min while using unmodified Bosch injectors (say by using an Xcessive LIM with the 4x secondary slots) than go for it I'd just be careful when it comes to WHO is doing any modification to the injectors, and HOW they are doing it.

I'm not sure what the largest EV14 injector sizing released from Bosch is, but if you can make it work than go for it

Someone correct me if I'm wrong, but having just purchased a set of EV-14s, I have certainly done my research.

ID's ARE EV-14s. The technology isn't similar, it is the exact same.

What Injector Dynamics do is purchase large quantities of EV-14s, flow test them, and pair them up with others that tested similarily - what they call "dynamic matching."

Here is a link: http://www.injectordynamics.com/dynamicmatch.html

Basically you are paying more to have the injectors flow matched, and you get a piece of paper confirming that. If that is worth the extra price to you then so be it.


There. Do i get internet points?

i like to run id injectors i think they are the best in market thats why they expensive to buy ,my traget is between 450 and 500 bhp so im sure i can achiev that with set of 4 1000cc,2000cc with my current mods.
atleast i dont have to worry to change them in future if i need to get more power witches i dont if i hit 500bhp.

Keep reading and you'll find this: The Same as Injector Dynamics But Cheaper

As I alluded to earlier, all the aftermarket companies modify the injectors to increase flow (what vehicle required 2000cc injectors from the factory?) the difference is HOW they are modified.

Also, if you keep reading from the source you quoted than you would find this article: Injector Dynamics - Drillbits and Dipshits

I went with ID, they have a great reputation and product, plus Paul is cool.

Now I have 6,400cc's worth of injectors installed to go with my twin 340lph aeromotive stealth pumps. I won't need to upgrade the fuel system for quite a while.

From reading this, it sounds like they are talking about other flow matching companies who claim to do what ID does, but then they rip off their data etc. etc. Not the manufacturer of the injectors they use. (Bosch)

As I alluded to earlier, all the aftermarket companies modify the injectors to increase flow (what vehicle required 2000cc injectors from the factory?) the difference is HOW they are modified.

Also, if you keep reading from the source you quoted than you would find this article: Injector Dynamics - Drillbits and Dipshits
I agree that drilling injectors is an extremely stupid thing to do. That being said.. how does ID get 2000s? Because they clearly wouldn't want to drill them to modify flow..

Is it just a coincidence that the EV-14s also came in a 2000cc size?
I know you can't link to it from here but when i google EV-14 2000cc, it brings me to the page of a different rotary car club with a member selling new from bosch, in the package, undrilled, unpunched 2000cc EV-14s. So although they probably weren't used in an OEM application, you could still get 2000

A quote from an admin on the ID forum:
There are lots of rumors floating around (put out there by other guys that sell injectors) that other people have the same injectors as our ID2000, they're just not matched by the same process. This is correct, except the rest of the rumor is that the consistency from Bosch is so good that our dynamic matching process doesn't have any benefit. Unfortunately, this is far from the truth.

This is a deviation vs. pulsewidth chart for every 10th injector out of a batch. You can see that while static flow variance is pretty good, there is quite a spread at 2msec pulsewidth, where much of the life of the injector is spent and where you really see and feel a difference from cylinder to cylinder variations. About a 2% spread at static flow (which is where most people have the ability to test halfway accurately) and as much as a 13% spread at 2msec. Do you think a 13% variance from cylinder to cylinder at idle and part throttle will make a difference in how a car runs?
Then they back this up with the same pics from the link I posted earlier. They ARE the same as EV-14s, just flow tested again and matched.
The question lies in how much you trust Bosch's promises. Clearly, ID's dynamic matching process will have a benefit, but for double the price? eh..



Edit: sorry OP.. in the midst of all this I have gotten side tracked from your actual question. 110% FFE rails. They aren't even very expensive (especially for what you get).

Does FFE make a secondary rail for 2000s that will accomodate the stock primary with 550s?

^^^yes.

Funny thing about ID is that they have NOT been around as long as FIC or other companies that flow match injectors. Yet they claim that others rip off their stuff....lol

They all do the same thing. Period. All you're paying for is that fancy little purple sleeve that they put on it.

To each their own, but people need to get off the bandwagon.

As for the rails. FFE is the way to go. That's what I have and they're great.

I'm getting confused again here as usual ,I just looked to five motor website and they have large selection of all type and size injectors with really affordable prices so anyone recommend them.
If I keep search and read what people said I will never decide what to buy simple.

The low impedance injectors are OLD technology, like from the '70s i think, and don't offer nearly the same level of control as the new style injectors. I wouldn't buy them unless you're going for a lie budget, low power, build.

If you really want to get injectors from five-0 than i can sell you my old set of primaries (ev14 850cc ones) for pretty cheap. They have 1,500 miles on them, max.

Holy crap man, you really don't let up, do you?

You were going to get IDs over EV14s because they are "better." Now you are looking at a set of low impedance injectors?

Stay with an EV-14 body at the very least..



Edit: you are the same person who asked if making your car lighter would give you more horsepower. I'm done with this thread
