should i up grade injectors??

Are you replacing the springs???
The stock springs can't take the lift of that cam. Are you planning on porting the heads? The stock heads can't flow enough to do that cam justice. If your not porting the heads you would be better off with a CC305.
The stock injectors will be fine with the cam you plan, you will need to have the ECU reprogramed for the cam. Once you port the heads I would go with 36 lb injectors.

30lbers will more than do it for you when your heads are done. Other than that the stock ones can easily handle up to 400rwhp.

another option:
buy a AFPR and set it at 58psi with your stock injectors, and have the injector constant programmed at 30lb.
trick the engine into thinking it has bigger injectors....
bryan at pcmforless recommended this to me.
thats what i did anyway, it is good enough to trap 115mph....

you will also need colder spark plugs, you should upgrade your fuel pump to be safe.
my stock fuel pump died at 350rwhp you dont want that to happen when your sprayin......
try the N20 forum, they can help more.

You'll definitely need bigger injectors w/ a dry kit. A wet kit will add fuel w/ a separate nozzle whereas a dry kit relies on the injectors to introduce additional fuel into the chamber. On a 150dry, I'd go at least 36# injector and probably bump the fuel pressur e into the 50s just to be safe.
