Okay guys, so Im wanting to get bigger injectors cause I already did the coils and what not. I was wondering if 550cc is overkill? And if not what is a good brand to go with.. And lastly, should I replace all 6 at the same time, ive got the money to do so.

The stock injectors flow more than enough for an NA RX-8 there is no need to upgrade.

I know there is no need to, I just want to. Im gonna have to change them out eventually anyways

So change them out for new stock injectors. You don't need and could not use anymore fuel than the stock injectors can provide. Plus you would not have a clue as to how to change the tune in order to run them anyway.

The flashed ecu would not be good enough to handle bigger injectors?

There is no benefit to changing injectors. Even if you put 1000cc injectors, the ECU will quickly figure out that it's running way too rich and trim itself down to deliver the exact same amount of fuel as stock. Any ECU. You don't make power by injecting more fuel, you make power by injecting exactly the amount of fuel needed for the amount of air supplied.

Except that bigger injectors don't do well delivering very small amounts of fuel, so you could have a very messy idle.

All for a gain of 0 hp.

There is strictly no reason to do this.

Also this :
"I think mine is fried from the full headers back exhast I did lol"
Makes no sense. If you believe something's wrong, outline your symptoms because there might be important things you need to invest all that extra money into

^this, but for a real answer. There are many other factors in which injectors to use. Stock are good for over 100 HP more than the car makes. Unless you're going for big turbo power just stick with stock injectors.

And no the Racing beat flash will do nothing at all for bigger injectors. Add bigger then Your car will adjust trims hit the max and throw cel's. Then you'll need a custom tune which will wipe out the racing beat flash.

The car runs based on Airflow. If you replace things that allow you to flow more the car should automatically account for it.
