Upgrade the low pressure turbo in your 6.4L Ford Powerstroke with the insanely powerful KC 71mm Stage 1 Drop In Low Pressure Turbo. This is KC's entry level low pressure turbo that is designed to be used with stock injectors and still support up to 650hp. This is the only aftermarket low pressure turbo with a 4" inlet and ported anti-surge cover. This kit also features a 360 degree thrust bearing for added reliability. This turbo works great for tow rigs, stock trucks, and individuals that do not plan on upgrading injectors.
