im currently working on the setup i have listed in my sig and am hoping to purchase the cam and injectors this weekend.

my question being, i plan to run nitrous at some point and am wondering if i will need larger injectors than the 24#s im getting? ive been told you can go pretty far on 24's but in terms of a 100 shot will the fuel supply be sufficient?

Wet or dry kit? I'm assuming dry, since you're asking about the injectors? I'd be more concerned about whether the fuel pump is sufficient, since you didn't mention what pump you're running. A dry kit shuts down the return line to boost line pressure and add fuel. With some 24's, you'll probably be safe.

They make new pistons every day, so why worry?

With a proper tune and a 255lph fuel pump the 24# injectors should be safe to run down into the low 11's. The key here is maintaining and air fuel ration of 11.5 - 11.7 if you want to be on the safe side.
