About the Range Rover Sport Engine

This is the AJ133, the 5.0L supercharged gasoline V8 built by Jaguar Land Rover for performance SUVs like the Range Rover Sport, as the live page describes. It uses an Eaton TVS supercharger mounted between the cylinder banks in a compact V configuration, direct injection with twin high-pressure cam-driven fuel pumps, twin water-to-air intercoolers with a front-mounted heat exchanger, and variable cam timing on both intake and exhaust. Bosch engine management coordinates airflow and fuel, and the aluminum block and heads with flat-top boost-specific pistons and a 9.5:1 compression ratio are built to handle the supercharger's roughly 15 psi.

Why Range Rover Sport Owners Replace the Engine

High mileage, supercharger or cooling-system wear, and the demands of a heavy performance SUV are the usual reasons. A sound AJ133 restores the muscular, refined power, the deep V8 character, and the strong low-end torque that make the Range Rover Sport what it is, with the engine inspected for compression before it ships. Because outputs varied across the Supercharged and SVR variants, matching the right unit to your vehicle matters, which is why we confirm the exact variant and output by VIN.

Things to Confirm Before Ordering

• Your exact variant and output, confirmed by VIN; the page lists conflicting figures, and the AJ133 spanned roughly 503 to 550 hp across the Supercharged and SVR variants and model years
• Your software plan: ECU tuning and relearning are essential after installation, per the live FAQ, so plan for professional setup
• Your fuel and cooling: premium unleaded is required, and the radiator and coolant systems should be maintained to protect this supercharged engine
