The size of your injectors is sufficient for up to about 250hp. Controlling them is another matter, but you won't need to replace them unless you go beyond a big street port.

let me chime in my agreement....

You won't need biger injectors on a NA unless the motor is ported or you are using NOS.

NO reason to use them and you will loose HP putting them in unless the motor is radically moded

For clarification...
Bigger injectors are not necessary for a wet shot. If you are running over a 50 shot, you really shouldn't be running a dry shot anyway, and unless you have a seriously ported motor, a 50 shot will still have you under the max limit of the stock fuel injectors.
Without serious porting, bigger injkectors are rarely ever needed.
