im trying to get a little over 400 hp. I have 2 questions. First can i do this with an H.O stock turbo? Second, if i put 100hp injectors on will the H.O pump be able to support it or will it be a waste of time?

I have a 01 dodge cummins with a raptor 150, 5" exhaust, CAI, Edge comp. NV5600

 

Yes but you need a turbo to support the fuel

 

I had a he35 and 100hp plus edge j/a and it worked, I'd suspect the turbo and injectors would be ok, but he would not know for sure unless he has pyro to monitot EGT

 

i don't see it listed, and it's probably too obvious, but you WILL need a clutch! if you tow or haul much, the larger turbo will make the drivability way better, EGTs will be less of an issue

 

I second that. With the mods I have in my sig I could slip the stock clutch

 

I understand that the HO pumps respond well to injectors. More than the SO pumps do since the HO pumps are a higher pressure running pump.

 

That and I read on Dave's site the HO VP & injectors don't flow as much as SO VP & injectors.
That's why I bought an SO VP when mine quit.

 

I put a so pump when my Ho went out and It works great, you just need to keep an eye on your egt's!
