Toyota officially brought the 1KZ series into the 21st century in 2001 with the 1KD series turbo diesels. The 1KD features dual overhead camshafts, direct injection, and Toyota’s proprietary common rail high pressure fuel system termed “D-4D”. Simply put, the 1KD’s are amazing. Incredibly quiet with a serious torque band from 1,800-3,600 rpm.The first generation 1KD was released in 2001 and found it’s way into the early Landcruiser Prado. In 2005, Toyota updated the 1KD engines to the 1KD-FTV which featured a 32-bit ECU, a variable-nozzle turbocharger, and piezo-electric, multi-stage injectors with pilot injection. These additions raised the base power from 145 hp to 188 hp and increased torque from 220 ft/lbs to 310ft/lbs. The pilot injection dramatically reduced engine noise, emissions, and torque throughout the engine’s range. While Toyota never officially released the 1KD-FTV in North America reportedly due to newly adopted emissions standards in California, it has received several awards for the 1KD-FTV including achieving strict emissions compliance in Europe.
