Nissan ZD30 Engine
Power, Endurance & Proven Nissan Engineering

Nissan ZD30 Engine is a powerhouse known for its rugged reliability, strong torque delivery, and fuel-efficient performance. Built to handle the toughest conditions, this 3.0-litre inline-four DOHC engine is widely used in the Nissan Hardbody, Patrol, and Navara series.

With its turbocharged direct injection system (DI), the ZD30 engine produces approximately 125–170 horsepower (92–127 kW) and 353–400 Nm of torque, depending on the version and ECU tuning.

Its cast-iron block and aluminum cylinder head design offer durability under high load, making it ideal for both workhorse and off-road applications.

Engineered for longevity and torque-rich performance, the ZD30 provides smooth acceleration and exceptional pulling power even under heavy loads. It’s paired with either a manual or automatic transmission and uses common-rail diesel technology in later versions for improved fuel atomization and lower emissions.

The engine’s efficient cooling system, turbo intercooler, and precise fuel delivery ensure reliable performance and reduced wear, even in extreme heat or dust. This makes the ZD30 a popular replacement engine for fleet owners, 4×4 enthusiasts, and diesel specialists across Africa.

Common Weaknesses & Maintenance Notes

The ZD30 engine is strong and efficient, but like most turbo diesels, it requires diligent maintenance to perform at its best. Common issues include EGR valve carbon buildup, overheating due to neglected cooling systems, and turbo wear from extended oil-change intervals.

Regular use of high-quality synthetic diesel oil (5W-40), timely oil and filter changes, and ensuring proper coolant circulation will greatly extend its life. Periodic checks of the intercooler, turbocharger, and injector system help maintain consistent power and efficiency.

When properly maintained, the Nissan ZD30 Engine is capable of well over 400,000 km of dependable service, making it a trusted choice for both commercial and off-road vehicles.

Each Nissan ZD30 Engine is carefully inspected, compression-tested, and verified before sale. Our imported JDM and South African units are hand-picked from running vehicles, typically with low mileage (50,000–60,000 miles). Every engine is confirmed to be free of cracks, leaks, or internal damage, ensuring dependable installation and long service life.
