The best 2JZ GTE engine
The Toyota JZ series of engines are Toyota-produced gasoline inline-six-cylinder engines that replaced the M engines. All engines in the series feature a DOHC valvetrain with 4 valves per cylinder and a displacement of 2.5 and 3 liters. The engines are designed for longitudinal installation for use with rear-wheel drive or all-wheel drive. They were produced from 1990 to 2007 and were succeeded by the GR series of V6 engines.
According to the Toyota designation system, the Toyota JZ engine designation is deciphered as follows: the first digit denotes the generation (1 - first generation, 2 - second generation), the letters following the JZ digit are the engine code, and the remaining letters denote the version (G - DOHC valve timing with wide "performance" phases, T - turbocharging, E - electronically controlled fuel injection).

1JZ-GTE
The third generation 1JZ-GTE VVTi, installed in the 1989 Toyota Cressida MX83.
The first generation 1JZ-GTE was equipped with two CT12A turbochargers (twinturbo), mounted in parallel and With an under-wing intercooler, the factory engine produced 280 hp (210 kW) at 6,200 rpm and 363 N⋅m (265 lb⋅ft) at 4,800 rpm with a compression ratio of 8.5:1. The bore and stroke were the same as the 1JZ-GE: 86 x 71.5 mm. Some engine parts, such as the timing belt cover, featured the Yamaha logo, indicating their involvement in the cylinder head design. In 1991, the 1JZ-GTE was installed in the completely redesigned Soarer GT.
Production of the second-generation engine began in 1996. The engine featured VVT-i, a higher compression ratio (9.1:1), and a single, larger CT15B turbocharger. New valve stem seals with a titanium nitride coating were also introduced to reduce camshaft friction. These changes smoothed out the torque curve. and significantly lowered its top-end revs, as well as reduced fuel consumption.
The 1JZ-GTE was paired with a 4-speed automatic (A340/A341) or 5-speed manual (R154) transmission.
This engine was installed in the following vehicles:
Toyota Mark II / Chaser / Cresta
Toyota Mark II Blit
Toyota Soarer
Toyota Supra
Toyota Verossa
Toyota Crown
1JZ-FSE
In 2000, the 1JZ-FSE with D4 direct fuel injection was introduced. This was for improved environmental performance and fuel economy without sacrificing power compared to the base engine. The 1JZ-FSE utilized the same block as the standard 1JZ-GE. The cylinder head was the same, and the intake system was designed to allow the engine to operate at a very lean mixture of 20 to 40:1 under certain conditions. As a result, fuel consumption was reduced by 20%, while power reached 196 hp and 250 Nm.
2JZ-GE
Production began in 1991, with a displacement increased to 3 liters. The cylinder bore and stroke are square, measuring 86 mm. The first versions were equipped with a conventional DOHC valvetrain with four valves per cylinder. It produces 200 hp at 5800-6000 rpm and 298 Nm of torque at 4800 rpm. In the second generation, the engine acquired the VVT-i variable valve timing system and a DIS ignition system with one coil per pair of cylinders. Power increased to 220 hp at 5800-6000 rpm.
This engine was installed in the following vehicles:
