The Toyota KZ is one of Toyota's small passenger diesel engines.
1KZ-T
The 1KZ-T is a version of the KZ series engine that used a fully mechanical injector pump instead, {{convert|2982|cc|L|1|disp=flip|abbr=on}}, 4 cylinders, SOHC, 2 valve per cylinder turbo diesel engine. Compression ratio remains the same at 21.2:1. Maximum output is {{convert|123|hp|kW PS|0|abbr=on}} at 3600 rpm and maximum torque is {{convert|296|Nm|lbft|0|abbr=on}} at 2000 rpm.{{cite press release|author=|title=New 4runner Added To Toyota 4WD Line-up|url=https://media.toyota.co.uk/wp-content/files_mf/16007675254RunnerUKlaunchpack1993.pdf|format=PDF|location=The Quadrangle, Redhill, Surrey|publisher=Toyota GB|agency=|date=October 20, 1993|access-date=2021-04-01}}

1KZ-TE
The 1KZ-TE is a {{convert|2982|cc|L|1|disp=flip|abbr=on}}, 4 cylinder, SOHC, 2 valves per cylinder turbo diesel engine with indirect injection. Bore and stroke are {{convert|96x103|mm|2|abbr=on}}, with a compression ratio of 21.2:1. Maximum output is {{cvt|130|PS|kW hp|0}} at 3600 rpm with maximum torque of {{convert|287|Nm|lbft|0|abbr=on}}⋅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 {{cvt|140|PS|kW hp|0}} [Aust. {{convert|130|hp|kW PS|0|abbr=on}}] at 3600 rpm and maximum torque of {{convert|343|Nm|lbft|0|abbr=on}} at 2000 rpm.
