Default HP increase with Injectors only?

I have stock 240cc injectors in my b16 and i did alil homework on the injector on a 94-98 eclipse. The eclipse injectors could fit the b16 engine but increasing the CC's of the injectors, would it make more HP by just switching them? or would a regulator and fuel rail would be needed ?

you might get a little.........but i doubt ud notice it. FASTCIVIC did something like that BUT he did bigger injectors......fuel rail......adjustable fuel pressure regulator, and an ECU piggyback (i think he has the venom)......im not sure if he changed the fuel pump for a 255lph......but it would def help. LOL ANYway im goin to have to say u wont get much hp outta the injectors unless u beef up the rest of the fuel system as well.

How much bigger are the eclipse injectors that the stock ones on your b16? Usually when you replace injectors you get a fuel pressure regulator and a fuel rail. But, just replacing the injectors could make your car run rich. Remember more gas doesn't equal more power, what could happen is that you could actually lose power. You have to have the air and fuel ratios balanced. This could require a VAFC. Saciocons will have the full awnser to your question.

so should i get a fuel regulator and fuel rail to push more fuel to the stock injectors instead of getting the eclipse injectors ?

Yes please give a mod list. If your car is stock, this mod will do nothing except hurt the car.

You can make it pump more fuel, but without forced induction/nitrous you wont really get it to pump more air. Like said above... all you will be doing is making it run rich (which is good for detonation control) but after a certain point running rich actually hurts you. If you add fuel you must add air...

exactly... If you want to put more fuel in the motor figure out a way to get more air in it as well. A way to start would be getting a larger TB and an aftermarket intake manifold, and or a turbo or a supercharger.
