FAQ
Will this fit my LB7 without custom fabrication?Yes. It’s a direct replacement CP3 for LB7 platforms (01–04). Supporting mods are required to take advantage of the added fuel.
Do I need a lift pump?Yes, a quality lift pump is highly recommended to maintain adequate inlet supply to the high-pressure pump at elevated demand.
How big are the gains?Output is ~120% over stock CP3 capacity. Actual horsepower depends on turbo, injectors, tuning, and overall setup.
Is there a core charge?Yes. Like-for-like core required; vendors commonly list a refundable core (e.g., $300) after acceptable core return.
Is this CARB legal?No. Competition/race-use only for on-road vehicles in emissions-regulated areas.
