The 2JZ engine was an engine manufactured by Toyota. It is part of the Toyota JZ engine family, the successor to the Toyota M engine family, along with the 1JZ engine, a 2.5 liter version of the engine. There are 3 versions of the engine that came from the factory. These are the 2JZ-GE, 2JZ-GTE, and the 2JZ-FSE.

The 2JZ engine is a 3.0 liter engine that was first produced in 1991[1]. As a stroked version of the 1JZ, it had a square cylinder bore and stroke dimensions, 86 mm × 86 mm (3.39 in × 3.39 in), making the engine block taller than the 1JZ (86 mm × 71.5 mm (3.39 in × 2.81 in)) by 14.5 mm (0.57 in).


2JZ-GE[edit]

The 2JZ-GE was a naturally aspirated version of the 2JZ. It uses a 10:1 compression ratio, a dual-stage manifold and output 215–230 PS (158–169 kW; 212–227 bhp) at 5800 to 6000 rpm and 209–220 lb⋅ft (283–298 N⋅m) of torque at 3800 to 4800 rpm. It first appeared in 1991 in the vehicles the Toyota Crown Royal, Crown Majesta and Aristo. In the engine code, “G” stands for performance-oriented dual overhead cam setup and the “E” means its electronically fuel injected.[2]

2JZ-GTE[edit]

The 2JZ-GTE was a twin-turbocharged version of the 2JZ. Other than just being turbocharged, the GTE version had a static compression ratio of 8.5:1 and commercially cited output from 230 PS (169 kW; 227 hp) to the contemporary industry maximum of 280 PS (206 kW; 276 hp) at 5600 rpm. The torque was advertised as 44.3 kg⋅m (320 lb⋅ft; 434 N⋅m) at 4000 rpm to be later recited as 46 kg⋅m (333 lb⋅ft; 451 N⋅m) with the introduction VVT-i (Variable Valve Timing) in production year 1997. The engine code is similar to the 2JZ-GE, but within the code, the "T" stood for turbocharged.

Although it was commercially advertised to have 280 PS due to Japan's gentleman's agreement, in North American and European markets, the A80 MK4 Supra—which launched for 1993 with bigger injectors, stronger turbos and different cams—was recorded and documented by Toyota as 325 PS (239 kW; 320 hp) at 5,600 rpm.

2JZ-FSE[edit]

In the year 2000, Toyota introduced the 2JZ-FSE along side the 1JZ-FSE, direct injection variants of their respective engines. Although the least recognized variants of the engines, their goal with the FSE variant was to achieve minimal emissions and fuel consumption together with no loss of performance. The 3-litre 2JZ-FSE uns an even higher 11.3:1 compression ratio while matching the conventional VVT-i 2JZ-GE with 162 kW (217 hp; 220 PS) and 294 N⋅m (217 lb⋅ft) of torque. The 2JZ-FSE is always used with an automatic transmission.

Reputation[edit]

The 2JZ-GTE, according to the tuning community, is the most revered engine of the 2JZ line. Its reputation of the build quality being strong is a reason behind its reputation and recognition. The engine is a cast iron block, which is great for the strength of the engine. Being also a closed-deck engine, the cylinders are strong, making the engine able to handle a lot of boost pressure, a lot of air, without compromising engine structure. It can also handle high boost pressure due to it having a well-designed three-layer steel head gasket. Also, the crankshaft is made out of forged steel, which is another added strength to the engine.[3] Also, due to it being an straight-six layout, the engine is naturally balanced unlike a V-layout engine.[4] With its reputation being a strong engine and high potential, this often leads the 2JZ-GTE to be engine swapped in to other vehicles for motor-sports like drifting.

The 2JZ-GTE is also mentioned and used in a MK4 Supra in the popular movie The Fast and the Furious, giving the engine more recognition through pop culture. There is a scene where they are assembling and tuning the engine[5] and even race the Supra with the engine against a Ferrari F355 Spider to show the potential of the engine and the Supra[6].

The 2JZ-GE and 2JZ-FSE do not have the reputation of the 2JZ-GTE because the GE and FSE had lower tuning potential [7] and the GTE version got special treatment in terms of the internals due to it being turbocharged.[8]
