This is a brand new Genuine Nissan YS23 M9T long engine assembly, a direct replacement for Nissan Navara NP300 D23 models fitted with the twin-turbo YS23TT diesel engine. It's the definitive solution for a motor that has suffered catastrophic internal failure, such as seizure, a cracked block, piston damage or severe overheating. An engine showing signs like loud knocking, excessive smoke, or metal in the oil requires a complete replacement, and this genuine unit is the highest-quality fix available.

As a 'long engine' assembly, this unit comes substantially complete to simplify your engine swap. It includes critical components like the water pump, oil cooler, vacuum pump, fuel rail, glow plugs, and brand new genuine injectors. The assembly is built up from the sump to the rocker cover and includes the timing cover, harmonic balancer, and rear main seal, providing a solid foundation for your build and getting your Navara back on the road sooner.

Installation & Warranty Information

Engine replacement is a complex task recommended for professional workshops only. It requires a vehicle hoist, specialised diagnostic and engine lifting equipment, and extensive mechanical expertise. You will need to transfer over accessories from your old engine such as the alternator, starter motor, A/C compressor, and turbochargers. For a trouble-free installation, we strongly recommend also replacing all engine mounts, drive belts, radiator hoses, coolant, and engine oil.

To ensure warranty compliance, the following conditions must be met:

• Warranty Requirement Met: Because this engine includes brand new genuine fuel injectors, the strictest condition of engine warranty is met. Please retain your installation invoice as proof.
• The warranty is void if aftermarket performance components (e.g., upgraded turbos, ECU tunes, or non-genuine injectors) are fitted.
• Engine oil and filter must be changed within the first 1,000 km after installation.
• The use of non-genuine ancillary parts during installation may affect warranty eligibility and will be assessed on a case-by-case basis.
• Prior to engine start the YS23 cooling system bleed instructions must be followed to ensure all trapped air is removed from the cooling system

Vehicle Fitment
