Default Bigger Injectors

Hey everyone got a question about injectors. How big is too big where my truck really wont be streetable anymore. It is still my daily driver and I'm looking at 150Hp or 160Hp sticks. I am buying an Airdog II 165GPH pump and I'm guessing will have to buy an upgraded CP3 as well. Now budget only allows so much so I will be doing this on the stock turbo until I get buy a bigger one of those but will this kill my stock one? Any info would be great as I'm trying to figure how to best spend my money on bombs and that wont in turn bomb my truck. Thanks for the help!

You will have to upgrade your CP3. If you turn your box down and dont do a lot of heavy towing you can get by for a while on a stock turbo. I would look at doing a turbo first then injectors.

I just put 90s in last week. They work awesome.

I have no fuel issues with my stock cp3. I also just put the airdog 150 a few weeks ago.

I might put the arson kit on my cp3 pump later to increase the flow. It's cheap and easy to do. don't even have to remove it

The size that you can daily drive comes down to the charger set up and programing your going to run. We have a truck here with twins II race series 250hp injectors and its a daily driver. Tow sleds out west, drives it to the races/sled pulls, ect.

Thanks for the input so far. My goal is for over 700hp and to be a mainly daily driver with some occassional sled pulls drags and dynos. Sounds like alot of guys are running 90's will that get me to my HP goals cause i don't want to run nitrous (just yet). Or is 150 way too much and I should look at say a 120HP stick. Also would it be more beneficial to me to upgrade the turbo first. Really like Industrial Injections Silver Bullet 66 74 14 but not quite sure if I have the fuel to push that big of a turbo yet so you see my dilemma. Always open for suggestions.

I'd put the race series II injectors in. Then keep the programing down until you get the
fuel pump and turbo to run it. Your goal of 700rwhp DD is very easily done.

When you put the turbo on done a two piece manifold at the same time.
