Nissan K9K Diesel Engine.

Compact Power with Proven Efficiency

Nissan K9K Diesel Engine is a highly efficient and reliable power unit, co-developed by Nissan and Renault, designed to deliver outstanding fuel economy, low emissions, and dependable performance.

Built with modern engineering precision, this 1.5-litre inline-four, DOHC, 8-valve turbocharged diesel engine has become one of the most successful small diesel engines in the world.

It powers popular models like the Nissan NP200, Micra, Almera, and Renault Duster, making it a versatile and trusted choice for both commercial and private vehicles. Featuring a displacement of 1,461 cc, the K9K produces between 65–110 horsepower (48–81 kW) and up to 260 Nm of torque, depending on the version and turbo system.

The engine employs Common Rail Direct Injection (CRDi) technology, ensuring smooth acceleration, excellent throttle response, and superior fuel efficiency — often exceeding 20 km/L under optimal driving conditions.

Its lightweight aluminium alloy head and durable cast-iron block balance efficiency with long-term durability, while the variable geometry turbocharger (VGT) provides strong low-end torque and consistent performance. Maintenance for the K9K engine is straightforward and affordable. Regular oil and filter changes every 10,000–15,000 km with quality 5W-30 synthetic oil help preserve engine life and turbo health.

Thanks to its robust design, many K9K engines reach 300,000 km or more with proper care. Every unit we import is hand-inspected, compression-tested, and verified to be free from cracks or damage, sourced directly from low-mileage Japanese and European vehicles.

Common Weaknesses & Maintenance Notes.

The Nissan K9K Diesel Engine is widely recognized for its excellent fuel economy and durability, but like any modern diesel, it performs best with regular servicing and quality fluids. Over extended mileage, some engines may show injector carbon buildup or EGR valve clogging, especially when driven mainly on short city trips.

These issues are easy to prevent with timely oil changes, fuel filter replacements, and occasional long-distance drives to keep the system clean. Another area that benefits from care is the turbocharger and timing belt. Replacing the timing belt every 90,000–120,000 km and ensuring consistent oil quality helps the turbo run smoothly and prolongs overall engine life.

With proper maintenance, the K9K often exceeds 300,000 km without major repairs, a testament to its solid engineering and reliability. This engine is particularly popular for its low running costs, smooth operation, and quiet performance, making it ideal for daily commuters and light commercial vehicles alike.

Each unit we sell is hand-picked, inspected, and compression-tested before shipping, ensuring customers receive a clean, fully functional, and ready-to-install engine directly from Japan or Europe. With professional installation and routine care, your K9K dCi engine will deliver years of strong, efficient performance on every drive.

Whether you’re replacing an old engine or upgrading your vehicle for reliability and efficiency, the Nissan K9K dCi 1.5L Turbo Diesel offers an ideal combination of performance, economy, and endurance, making it one of the most trusted engines in Nissan’s modern diesel lineup.
