Default Will i be ok with just a pump?

I got a cammed full boltons 02 ls1.
Next time i go home i am going to lean out my tune a bit and makea smoother transition of a/f on WOT so I am not sure what the IDC will be. These are stock 28 lb injectors.


I am now thinking about adding a wet nitrous kit 75-150, most likely going to spray 100. Now my question is that since wet kit supply additional fuel through the fuel port, will i be ok with just changing my fuel pump?
I am thinking a 255lph holley or racetronix.

you will prolly need injectors too. the only difference you are going to see with the pump is your fuel pressure from a normal 50 or so psi to 58-62psi with the pump. thats not going to net you a lot of room.

3x#ers or even 42#ers would do perfect, and even if you have more mods

i'm at 5psi and running 64% duty cycle.

Thing is, since it is a wet kit, it actually takes fuel from the test port out of that psi. So there is fuel from another source besides the injectors.

You're right, if that's all you have planned, there is no need to upgrade injectors at this point. The fuel for a wet kit is supplied via the fuel solenoid from the schrader valve (make sure to remove the valve core or you'll effectively be running a dry shot and with stock injectors, that's asking for trouble!)

If you plan on making more power N/A though, larger injectors are a very good idea. As mentioned above, if you go that route, just go straight for 42#'s. Skip the 30# crap. I know I wish I would have..

Ok sounds good. In all honesty, once i get the setup, if injectors are needed according to duty cycle, i will go up to 42's. Just wanted to get an idea.

Btw, how do you remove the schrader valve core? Do you just use one of those tools for removing a tire fill valve?
