Development of Toyota JZ Type Engine Series 930881
The newly-developed 2JZ engine series is available in two types; a naturally aspirated 2JZ-GE and a turbo charged 2JZ-GTE. Both have in-Line-6 cylinder arrangement and displacement volume of 2.997 liters and have attained many features expected for the engines of new era by utilizing new technologies, such as DOHC 4 valve, high compression ratio, a highly rigid structural design which is realized by extensive use of the CAE, a serpentine accessory drive belt, and auto tensioners for timing belt and accessory belt systems. These engines are stroke up versions of the 1JZ engines.
The 2JZ-GE engine, which has been developed for the SC300, delivers high performance of 169 KW/6000rpm and 284 Nm/4800rpm by adopting a variable induction system, a knock-control system with two sensors, etc.
The other type, the 2JZ-GTE engine which has been developed for the Aristo in japan includes a TWO-WAY-TWIN-TURBO’ system equipped with ceramic turbine wheels. With this system, the engine is allowed to selectively use a suitable turbo unit depending on the low/high speed range, thus providing excellent transient response and delivering easy-to-use torque characteristics in wide speed range. This engine delivers high performance of 206 KW/5600rpm and 431 Nm/3600rpm.
