what injector size would be suitable for a 250whp NA h22a1 engine ?

would i need resister box ?

I am running hondata s200

 

I'm using RC 370cc peak and hold injectors with my resistor box

and if you're gonna hit 250 all motor I'll be impressed

 

250 is what i am aiming for....... *call it a dream* are there any injectors where you dont need a resistor box..

 

the bigger the injector the better as long as you have a good engine management, id put some 440s on that ho

 

not really man.. bigger ones spray patterns are not quite as good.. but thats mainly talkin like really big ones.

 

that really depends on the injector. i like 440s in NA cars because i can have more control over the injector advance. we have daily driven cars running 1000cc and bigger injectors with zero problems. its all in teh tuning

 

I'd expect the injector size increase to be proportional to the power increase. That is, if a stock H22A1 has, oh, 150whp, and you want 250whp, then the required injector should be 250 / 150 * 340cc = 566cc. That's pretty big... but it seems about right if you want to have similar duty cycle.
