My 460cc were from 1990... and they did a great job for 4 years upto 15psi (94%), I'll take the chance.
good luck idling better than 13.0:1.

seriously, why did you start this thread?

No you didn't.

You wanted someone to validate the decision you had already made prior to making the thread.

So i am to believe that the input you asked for, that multiple people gave their time to supply, resulted in you buying these injectors?

The first one gave no input, second one said they flowed less then advertised, third and all the rest - no input.
My own experience was 4 years with 1990 rx7 460cc that did good.

For less then a fifth of the ID price I was willing to get 850cc that will flow 750cc.

I'm not sure how one can spend more than 30 minutes on this website and NOT gain an understanding that it's not about flow.

Like it or not, every post you're referencing was input. It's just not the input that you wanted when you created the thread.

You asked, and i quote:

The first 4 replies were input. The input provided was "No, they are not."

1st post had no merits? have you researched? I deserve cats for giving you a straight forward responce which is essentially all you needed to know if you bothered to google mx5 ev14's.

However go have **** idle, bad spray patterns, tuning issues and then future injector problems. Your time wasted is better than my time wasted.

drop mic.

I know about ev14 and I did my research, I had a simple question about getting the same kind of injectors that served me well for 4 years just with higher flow - that is all.

Yes, your sloppy dick Rx7 injectors served you well for 4 years. we get it.

here's a quick question: what PW do you idle at?

that's the cycle time of 800cc injectors... without any fuel being injected.

1ms idle is totally normal.

you didn't buy ID injectors. From that same page:

Using just this sort of data, we have been able to determine the fuel usage of numerous engines at idle. How did we do that? Magic maybe? Nope…It’s as simple as recording the idle pulse width of a running vehicle, and then comparing that value to the curves above to determine idle fuel flow.

Having this ability has allowed us to steer customers in the right direction knowing nothing more than engine displacement. It has also allowed us to sort the good from the bad insuring that everything we release is a quality piece. By examining the flow vs pulse width curves of any injector we can answer important questions such as “Will this injector provide a stiochiometric idle on a 1.8 liter Honda engine?” “Or a 1000cc 4 cylinder motorcycle engine?”

We don’t need to wait for our pet tuner to try it out on his EVO, or his buddy’s WRX, we know before its ever installed in a running vehicle.

So am I bragging? Not really. Just trying to make a point. If I had to hand this in for a grade, my point, or more accurately my conclusion would be that it is no longer 1985. For that matter, it is no longer 2008.

This industry as a whole has moved forward at a rapid rate, and the ability to form logical conclusions from data, and to expect the availability of that data is commonplace.

Gone are the days of tuning poorly-behaved injectors with little data, and even less understanding of what makes them perform so poorly. Gone are the days of asking your injector supplier for pertinent data and getting a response ranging from a condescending attitude, to a blank stare.

So if you see an exception to this forward momentum, do the whole industry a favor and remind the offenders that its no longer 1985.

If this article left you with an unanswered question, please let us know and we will be happy to clarify it for you.
you have injectors from earlier than 1985...

I understand your point, I canceled the old 850cc and got ev14 1000cc kit for the miata.
