If you want 400 hp in a 7.3 PSD, you're going to need a big turbo, big injectors, big oil, big fuel system, good custom tune, and of course all the minor little things. Then you need a clutch if it is stick, or a built tranny if it is auto.
You'll easily reach $5,000+ doing this.
you dont need big oil,the 17* hpop will support 450HP with no problem.dont really need the big fuel either till you get around 450HP at the wheelsstage 2 injectors and a nice chip is enough.im still running my stock turbo.
