I got an 02 dodge cummins that has a stock vp44 and Turbo. how big of injectors can I run without upgrading my turbo or injection pump? I do have a Titanuim Fass lift pump on it and and edge juice w additude on it. Other then that its stock.

 

Welcome to the site! I'm no diesel mechanic, but I installed 100hp injectors before my turbo was upgraded and had no issues. It's possible to spool the stock turbo beyond its efficiency pressure range though and EGTs can get high pretty quickly. A boost elbow on the wastegate will allow you to tune the max pressure. I'm sure you'll get more responses to help you decide what to do.

 

If you tow I would not go over 100hp but if you don't tow you could get by with 150hp if you keep a close eye on your EGTs

Thanks for the help!

Im going to get 150 hp injectors installed and also get it to lope.

 

Lope is hard on your motor. I know it kinda sounds cool but you dont need it.

 

Im running 100's and love them with the edge juice chip. EGTs get pretty hot real quick but long as you have a gauge youll be good also they are great for towing almost dont need the chip at all.

 

How is a lope hard on an engine??
