quick injector question
 

Hey fellas, new to the forum but been driving a Cummins for about 12 yrs now. My last one was a 99 24V that I left bone stock. Now I have a 04.5 and want to do some playing with it.

I plan to get a edge juice w/attitude, some sort of full exhaust, fass fuel system and nozzles. I've been thinking about 75 or 100s for nozzles. My question is what do you guys recommend and what's the difference between new style and old style body injectors?

Really depends on what you want to use the truck for?! Your exhuast is 4" from the factory so you really do not have to mess with it unles you want a different sound.
Injectors need to be tested don't just throw nozzles on it you'll be sorry! if you want decent milage leave stock injectors they will make over 600hp! No difference really in the injector bodies. Fill in the blanks and we can guide you a little better!

Start with a new transmission.
