Description

The Toyota 1KZ-TE 3.0L Turbo Diesel Engine is one of the most durable and respected diesel engines ever produced by Toyota. Known for its powerful performance, low-end torque, and fuel efficiency, it’s a popular choice for 4×4 vehicles across the Hilux Surf, Prado, and Hiace ranges. This complete JDM 1KZ-TE package includes the 4×4 automatic transmission, wiring harness, and ECU, making it a ready-to-install solution for both direct replacements and custom diesel conversions. Each unit is thoroughly inspected and tested to ensure dependable, long-term operation.

The 1KZ-TE is a 3.0-liter inline-four turbo diesel engine equipped with electronic fuel injection (EFI) and a water-cooled intercooler, delivering exceptional balance between strength and efficiency. It produces approximately 130–145 horsepower and 343 Nm of torque, depending on the vehicle and ECU calibration. Built with a cast-iron block and aluminum alloy cylinder head, this engine is engineered to endure extreme heat, heavy loads, and long operating hours, making it perfect for off-road adventures and commercial applications.

Each engine is carefully tested before shipping. Our quality control process includes compression testing, leak-down inspection, oil pressure verification, and turbocharger performance evaluation. The wiring harness and ECU are checked for proper function, ensuring a complete plug-and-play setup. With average mileage between 40,000–65,000 miles, these engines provide excellent value, offering the strength of an OEM Toyota diesel unit with plenty of life left for years of reliable service.
