The pressure output will be the Fuel Pressure which is 43.5 psi. If you want to get larger injectors with larger openings to get more flow, you may have to get a larger fuel pump and you WILL have to have the computer reprogrammed. I work in a shop that does competition tuning for race cars and we take Acuras and put in K type engines and then redo the fuel injection, with a high level of success, 1st place SCCA etc. So, if you want to replace the injectors and change the flow, be prepared to re-do some or most of the fuel system and engine computer programming.
