Turbocharger CHRA for Land Rover Discovery Jaguar XJ 778400-0005 LR049590

Premium Turbocharger CHRA for Land Rover Discovery & Jaguar XJ | 3.0L TDV6 Right Side

Restore the effortless torque, smooth acceleration, and refined highway performance of your luxury vehicle with this premium Turbocharger CHRA (Center Housing Rotating Assembly) cartridge. Specifically engineered for the high-output 3.0L twin-turbo diesel V6 engine platform, this high-precision core replacement resolves common luxury diesel issues such as sluggish acceleration, low boost faults, and oil smoking from the exhaust.

This drop-in core cartridge is designed for the primary Garrett GT14V wastegate turbocharger architecture mounted on the Right-Hand Side (RHS / Passenger Side) of the engine. It matches manufacturer reference 778400-0005 (or 778400-5005S) and Land Rover OEM number LR049590. Opting for a precision CHRA rebuild allows you to swap out the high-wear internal rotating structures while completely saving the significant cost of replacing the complex electronic actuator setup and outer turbine housings.

Critical Benefits for Your 3.0L Twin-Turbo Diesel

The 3.0L TDV6 engine utilizes a sophisticated sequential twin-turbo layout where the primary right-side turbo operates continuously. If the internal bearings develop shaft play or the seals wear down, it will cause severe low-end power lagging, push engine oil into the intercooler lines, or trigger an immediate "Performance Restricted" limp-mode warning on your dashboard. Rebuilding with this premium core ensures:

1. Immediate Power Recovery: Re-establishes strict boost compression parameters to eliminate flat-spots during initial off-the-line acceleration.

2. Excellent Fluid Containment: Employs premium internal piston ring seals to safeguard against engine oil pushing past the shaft and fouling the exhaust catalysts or intake tracts.

3. Perfect Factory Alignment: Machined to strict dimensional specifications to drop seamlessly into your original factory compressor backplate and turbine snail housings.

Professional Luxury Diesel Installation Protocol: Twin-turbo systems feature complex vacuum lines and tight engine bay clearances. When installing this replacement cartridge, it is mandatory to clear out the front-mounted intercooler of any residual oil, execute a complete engine oil flush, and fit a new oil filter. Always pre-fill the oil inlet port of the new CHRA with fresh synthetic oil before cranking the engine to prevent immediate dry-running friction damage to the fluid journal bearings.
