Default Injector size?

My set up is this
6.0L .030 over
Fast 102/102
Big cam
Walbro 255 pump
And a wet plate kit from nitrous express
I wanna spray a 250 shot and Texas speed gave me fast 36lb injectors. Will I be ok with these or do I need bigger injectors?
Thanks.

injectors size plays a bigger role when its a dry kit. i think you will be fine with the 36's. whats the duty cycle right now???

A wet kit is really more dependent on your fuel pump/pressure.
A dry kit is more dependent on your Injectors.

Your injectors are going to be fine since the wet shot uses the fuel solenoid and jets to control the nitrous to fuel mixture. There is one concern that i would like to bring up.

My thinking is that you are going to run out of fuel pump on your set up especially with a 250 shot. You will probably be wanting to run a dedicated fuel system on this setup for the nitrous or you could redo your fuel system front to back. The most cost effective fix would be a dedicated.
