1KZ-T

The 1KZ-T is a version of the KZ series engine that used a fully mechanical injector pump. It is a 3.0 L (2,982 cc), 4 cylinders, SOHC, 2 valves per cylinder turbo diesel engine. The compression ratio is 21.2:1. The maximum output is 123 hp (92 kW; 125 PS) at 3600 rpm and the maximum torque is 296 N⋅m (218 lb⋅ft) at 2000 rpm. [1]

1KZ-TE

The 1KZ-TE is a 3.0 L (2,982 cc), 4 cylinder, SOHC, 2 valves per cylinder turbo diesel engine with indirect injection. The bore and the stroke are 96 mm × 103 mm (3.78 in × 4.06 in), with a compression ratio of 21.2:1. Maximum output is 128 hp (95 kW; 130 PS) at 3600 rpm with a maximum torque of 287 N⋅m (212 lb⋅ft)⋅m (212⋅ft) at 2000 rpm. The redline is 4400 rpm. Introduced as the replacement of the 2.4 2L-TE engine in Toyota's Light Duty Commercial Vehicles in Japan, it was first included in the 70-series Prado in May of 1993 followed by the Hiace and Hilux Surf in August of the same year. The 1KZ-TE also adopts the electronically controlled fuel injection, ETCS-i (Electronic throttle control System - intelligent) technology which is similar in basic construction to a modern gasoline injector, although using considerably higher injection pressures, it is an indirect injection engine which gives it a significant efficiency and fuel consumption penalty. It was replaced in most markets with the 1KD-FTV engine which uses common rail direct injection.

Used in KZN130 (Japan market), KZJ71W, KZJ78W, KZN160 and KZN165R (Australian & South African delivered model).

The intercooler equipped version of the engine increases the output of the engine 138 hp (103 kW; 140 PS) [Aust. 130 hp (97 kW; 132 PS)] at 3600 rpm and a maximum torque of 343 N⋅m (253 lb⋅ft) at 2000 rpm.
