The build everyone warned him about — done as a system instead of a parts list.


Own a 1,000 horsepower truck that can still drive to Orlando for dinner without being miserable.
Big power on a 5.9L is not a single decision, it is a sequence. We built this truck around the head studs and fuel system first, then sized the turbo and driveline to what the fuel would support. Nothing was bought twice.

Every component is linked with its real price. The set comes to $7,440 at list — add the ones your truck actually needs.
