Toyota’s most efficient turbo diesel engine, is now also the most desirable engine swap. The 1KZ-TE turbo diesel engine is a 4 cylinder 3.0L (2982 cc) SOHC with 2 valves per cylinder. Bore is 96mm and stroke is 103mm with a compression ratio of 21.2:1. Maximum output is 130 hp (97 kW) @ 3600 rpm and a maximum torque of 29.3 kgf-m (287 N-m) @ 2000 rpm. Max rpm is 4400. Importers can find these engines  in KZJ71W, KZJ78W, KZN160 model Toyotas

The intercooler equipped version of the engine power up to maximum output of 145 hp (108 kW) @ 3600 rpm and maximum torque of 35.0 kgf·m (343 N·m) @ 2000 rpm. Found in KZJ90 (Prado, Colorado 3-door), KZJ95 (Prado, Colorado 5-door)

Using an aluminium cross-flow cylinder head, the 1KZ-TE diesel utilizes a deep-skirt externally ribbed cylinder block for greater rigidity. Scissor gears on both the front and back of the timing gear idler and twin gear-driven balance shafts help to further reduce engine vibration. The aluminium pistons have a top ring groove of fiber reinforced metal.

The turbo is a lightweight compact design that is water-cooled for durability and to help combat the turbo diesel’s high operating temperatures trucks are fitted with a larger radiator, revised fan shroud, and long-life coolant. The new ceramic glow plugs heat up very quickly; even on cold early-morning starts.  Boost pressure is set at 7.4-9.7 psi (51-67kpa).
