I have a 2003 cummins and my next step is to change out my injectors and fuel pump. I was thinking about putting in 100hp or maybe 125hp injectors with an air dog 150gph fuel pump. My concern is the turbo. I will eventually get around to changing turbo and intercooler but unitl i do will the stock turbo be sufficient?

 

If you go with that size injector you will also need to upgrade your CP3 pump. I would try to do injectors and turbo at the same time.

im with luke.

 

And with that, keep in mind reliability goes right out the window.
