I'm only gonna be going with about a 75 to 100 shot, I'm probably not gonna be doing it till my mods are all together and on my car but i wanna know if I should upgrade injectors and what size to go with.
The mods are going to be as follows:
-Fully ported and polished heads with 2"/1.55" SS valves
-LT4 Hotcam Valve springs (with 1.5 rockers)
-Intake manifold ported to match the heads
-CC305 cam
-machine ported descreened mas air flow with middle bar removed
-K&N CAI
-shorty headers (yeah yeah I know, but i got a really good deal, lol)
-lunati timing chain set
-new oil pump
-msd 6AL
-msd blaster coil
-msd wires
-lt4 knock module
-3" catback exhaust with 3" cutout
-3.42 gears
-Rebuilt 4l60 tranny from a 93
-All this is gonna be on a stock bottom end with 113k on it, Its in a 94 formula.

So i just wanted to know if I should upgrade injectors or what? or should I just invest another $70 on a fuel solenoid and run a wet shot.

Th kit I bought off a friend came with two sneaky pete bottles(which I traded with $25 for a 10LB bottle) braided lines, Super powershot solenoid (for purge), and a Super Powershot for N2O, a fogger nozzle and a button. I got the kit for $150 (plus another $25 for the 10lb bottle) But like I said should i go with bigger injectors or a wet kit? Thanks in advance for any advice..

 

Regardless if you decide to go wet or not...I would move up to 30# injectors. When you start spraying you will be maxing out the stockers. I perfer wet over dry...but that's just my opinion.

 

How do you plan to add the extra fuel, only when you spray? Most dry kits for the LT1 use a slipstream from the NOS line to apply a pressure to the fuel pressure regulator, and boost the fuel pressure to the amount required to supply the extra fuel when you spray. If you have some loose pieces, and no way to alter the fuel pressure when you spray, you are sort of screwed with the stock PCM. You have to tune it for the "NA" application (and yes, 30# injectors would be a good idea), and then you have to figure out how to boost the fuel pressure to get the required increase in fuel through the injectors when you spray.

I run a dry setup, but I have an aftermarket ECU that has multiple program capabilities, so its got one tune for running without the nitrous, and another that increases the fuel and tweeks the timing when I spray.
