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

Applications:

• 4Runner KZN130L^[1]
• Hilux
• Land Cruiser II KZJ77

The 1KZ-TE is a 3.0 L (2,982 cc), 4 cylinder, SOHC, 2 valves per cylinder turbo diesel engine with indirect injection. Bore and stroke are 96 mm × 103 mm (3.78 in × 4.06 in), with a compression ratio of 21.2:1. Maximum output is 130 PS (96 kW; 128 hp) at 3600 rpm with maximum torque of 287 N⋅m (212 lb⋅ft)⋅m (212⋅ft) at 2000 rpm. Redline is 4400 rpm. Introduced as the replacement of the 2.4 2LTE engine in Toyota's Light Duty Commercial Vehicles in Japan, it was first introduced 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 140 PS (103 kW; 138 hp) [Aust. 130 hp (97 kW; 132 PS)] at 3600 rpm and maximum torque of 343 N⋅m (253 lb⋅ft) at 2000 rpm.

Applications:

• Land Cruiser Prado KZJ90, KZJ95, KZJ120L, KZJ120R^[2]
• Land Cruiser Prado KZJ71W, KZJ73W, KZJ78W.^[3][4]
• Hilux Surf KZN130, KZN185
• Hilux KZN165
• Toyota HiAce
