Does any one have any good info about fuel injectors?.

Questions.

1. What size injectors are on the 3.0 v6 vtec. any one know

is the size based on the amount or ratio of fuel one injector injects?, how is this measured exactly?

2. When would one change them out?, i have 122k on engine.

3. Are fuel injectors something that you can upgrade?

4. what would this upgrade be, ie larger fule induction? qucker flow?

5. if this mod was done does engine ecu need to be altered?

1. 240cc, measured by the maximum amount of (cubic centimeters per min).
2. When they're faulty, they usually last, longer than other components.
3. You can upgrade them, but you will have to replace more than injectors and if not compiled with the correct components for control you may cause damage and disrupt the idle, instead of increasing power.
4. To benefit from bigger injectors you need forced induction, the ability to add more fuel needs the ability to add more air.
5. Yes, the ECU would need altered. You'd need a piggyback or a standalone to control the new injectors.
