500hp cummins
 

Looking to get 500hp out of my 99 cummins automatic. The tranny is ready to go have cold air intake. know I need a new lift pump 150gph is what I'm shooting for. Edge juice with attitude programmer. 150hp over stock injectors. What turbo setup would u guys suggest twin, single, and should I have to do anything else like head studs, intake horn, etc.

Studs for sure and probably o-rings to be safe. And turbo upgrade. Single will do it but compounds are preferable if funds permit. No intake horn needed. What size and hole count are your injectors?

don't need o-rings.

Studs, valve springs, and compounds will get you there with some 7x.011 injectors.

stock over S472 is a good cheap compound setup.

Where would I go about getting a cheap piping kit for the compounds?
