Nov 07, 2012 KZN1## series cars with the 1KZ-TE are prone to cracking the head, about 2k in parts from toyota (trade) About 1400 for the head alone. You can do a leak down test, and a TK head check test. Take it to a decent diesel specialist. Some one like Taupo Diesel Solutions Limited Taupo Area Yellow® NZ as I assume your in taupo from our messages. I got a phone call from a customer who had just fitted a new cylinder head onto his 1KZ 3 litre turbo diesel in a Toyota KZJ95 Landcruiser prado and it would not start. This shows a one issue.

The Toyota KZ is one of Toyota's small passenger diesel engines.
1KZ-T[edit]
The 1KZ-T is an early version of the KZ series engine and used a fully mechanical injector pump, 3.0 L (2,982 cc), 4 cylinders, SOHC, 2 valve per cylinder turbo diesel engine. Maximum output is 125 hp (93 kW; 127 PS) at 3600 rpm and maximum torque is 287 N⋅m (212 lb⋅ft) at 2000 rpm.
Applications:
- Land Cruiser Prado KZJ71W, KZJ78W.
- Toyota 4Runner KZN130L
1KZ-TE[edit]
The 1KZ-TE is a 3.0 L (2,982 cc), 4 cylinder, SOHC, 2 valves per cylinder turbodiesel engine with indirect injection. Bore and stroke is 96 mm × 103 mm (3.78 in × 4.06 in), with a compression ratio of 21.2:1. Maximum output is 130 hp (97 kW; 132 PS) at 3600 rpm with maximum torque of 287 N⋅m (212 lb⋅ft) at 2000 rpm. Redline is 4400 rpm. First produced in 1993, it is still used in new model vehicles today[citation needed]. 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 raildirect injection.
Used in KZJ71W, KZJ78W, KZN160 and KZN165R (Australian & South African delivered model).
The intercooler equipped version of the engine increases the output of the engine 145 hp (108 kW; 147 PS) [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[1]
- Hilux Surf KZN130, KZN185
- Hilux KZN165
