Nissan Hardbody / NP300 2.4 KA24 Engine

Description

The Nissan KA24 (specifically the KA24DE ) is arguably the most iconic petrol engine to ever power the Nissan Hardbody and NP300 range. Known globally for its nearly indestructible iron block and high-torque characteristics, it is the “big brother” to the KA20 and the engine that earned the Hardbody its reputation for being a relentless workhorse. Key Specifications & Features Type: 2.4L Inline 4-Cylinder, 16-Valve Valvetrain: Double Overhead Cam (DOHC) Fuel System: Multi-Point Electronic Fuel Injection (EGI) Power Output: Approximately 105 kW (141 hp) at 5,600 rpm. Torque: A stout 209 Nm at 3,600 rpm. Construction: Heavy-duty cast iron block with an aluminum alloy cylinder head. Performance Highlights Legendary Durability: The KA24 is famous for its “over-built” design. It uses a robust timing chain rather than a belt, which, if maintained with regular oil changes, can easily last the lifetime of the engine. Low-End Grunt: Unlike many 16-valve engines that need high revs to perform, the KA24 delivers peak torque early. This makes it exceptionally good for towing, off-roading, and carrying heavy loads in the NP300. Versatility: It strikes the perfect balance between the fuel economy of a four-cylinder and the pulling power typically associated with a small V6. Easy Maintenance: Its simple, non-turbocharged design makes it one of the most cost-effective engines to service, with parts widely available across North America and global markets. Common Applications The KA24DE is the heart of several legendary Nissan vehicles: Nissan Hardbody / NP300 (Both 4×2 and 4×4 Hi-Rider models). Nissan Terrano II / Mistral SUVs. Nissan 240SX (In the US market, where it is a favorite for tuning and drifting due to its strength).
