and head studs.and air intake

 

your not going to need twins for 450 rwhp in a cummins ... in a powerstroke you would but not in a cummins

 

a 63/68-12 would be a fun street trubo for that power level. Should clean the smoke up real well.

 

if i wer to use twin turbo how much more power would i get.and alright thanks for the info.what injectors shuld i use and wat fuel plate

 

Depends on how big you size your turbos...

 

and in this case bigger is not always better

 

62-68-12 over s475. 600hp is easily obtainable

 

If hes just wanting 450hp I would keep the 35 and use it over an HT3B. Would be cheaper that way. I would say #100 plate full forward and 5x.014's for that turbo setup. What year engine will you be using? You might want to change DV's also if you have 131's in right now.

 

its a 94

 

If Im not mistaken you have 131 DV's then.
