- 2JZ-GTE (Turbocharged): The 2JZ-GTE, the turbocharged variant of the 2JZ engine, became famous due to its association with the Toyota Supra Mark IV (A80), one of the most legendary performance cars in automotive history. The turbocharged version offers immense power potential and is known for being able to handle substantial amounts of boost without compromising reliability.
History of the 2JZ Engine
The 2JZ engine was introduced in 1991 as a successor to the 1JZ engine, which had already established Toyota’s reputation for producing durable, high-performance inline-six engines. The 2JZ series was a part of the Toyota Supra project, and the 2JZ-GTE engine, in particular, found a home in the fourth-generation Toyota Supra A80, which was produced from 1993 to 2002.
In the 1990s, Toyota was competing with performance models from manufacturers like Nissan and Mitsubishi, who were producing some of the most technologically advanced cars in the world. The 2JZ-GTE engine helped give the Supra its legendary status, offering 280 horsepower and 318 lb-ft of torque in its stock form, with potential for far more with aftermarket modifications.
The 2JZ engine was designed with durability in mind. Its solid iron block, robust internals, and high-flow cylinder head made it the perfect platform for tuning. Enthusiasts quickly began to push the limits of the 2JZ-GTE, building cars that produced over 1,000 horsepower with relative ease. This made the engine a favorite among drag racers, street racers, and performance enthusiasts who valued both power and reliability.
Key Features of the 2JZ Engine
What sets the 2JZ apart from other engines is its robust design and inherent ability to handle high power outputs. Here are some of the key features that make the 2JZ engine such a highly regarded piece of engineering:
1. Strong Engine Block
The 2JZ engine block is made of cast iron, which gives it a significant strength advantage over many other production engine blocks made from aluminum. This strength allows the engine to handle extreme amounts of power and boost without fear of cracking or warping, which is why it’s a favorite in high-performance builds.
2. Robust Internals
The internals of the 2JZ engine are built to last. The engine features forged steel crankshafts and high-strength pistons, which are able to withstand the stresses of forced induction and high-revving applications. This robustness means the engine can take a beating and keep running, even when producing significantly more power than it was originally designed for.
3. Excellent Tuning Potential
One of the most appealing aspects of the 2JZ engine is its tuning potential. Whether you have a naturally aspirated 2JZ-GE or a turbocharged 2JZ-GTE, the engine responds well to modifications. With upgrades like bigger turbos, stronger fuel systems, and engine management systems, the 2JZ can easily reach levels of power that many other engines can’t handle. This has made the 2JZ an icon in the tuning world.
4. Advanced Fuel System
The 2JZ-GTE is equipped with a sequential twin-turbo system, which provides smoother power delivery and better performance at both low and high RPMs. The multi-port fuel injection system ensures that the engine is provided with the precise amount of fuel for efficient combustion.
5. Overbuilt Head and Valve Train
The 2JZ’s cylinder head features DOHC (Dual Overhead Cam) and 24 valves, which helps it achieve high power outputs. The engine’s VVT-i (Variable Valve Timing) system also allows for better fuel efficiency and performance across different RPM ranges. The valve train is designed to handle high revs, making the 2JZ engine perfect for high-performance builds that require sustained high RPM operation.
Different Versions of the 2JZ Engine
There are several versions of the 2JZ engine, and the most commonly available in the market are the 2JZ-GE and the 2JZ-GTE.
2JZ-GE (Naturally Aspirated)
The 2JZ-GE is the naturally aspirated version of the 2JZ engine. It’s still a very capable engine, providing 220-230 horsepower depending on the application. The 2JZ-GE is often found in cars like the Toyota Aristo and the Lexus IS300, and it is known for its smooth power delivery, reliability, and durability.
Though it lacks the boost of the turbocharged 2JZ-GTE, the 2JZ-GE is a popular choice for enthusiasts looking to build a reliable engine that can handle forced induction or just provide a solid foundation for other performance upgrades. The 2JZ-GE is ideal for NA-turbo swaps, where the engine is modified to accept a turbocharger.
2JZ-GTE (Turbocharged)
The 2JZ-GTE is the turbocharged version of the 2JZ, which became famous through its use in the Toyota Supra A80. This engine produces around 280 horsepower in stock form, but it has the potential for much more with the right modifications. The 2JZ-GTE is often used in motorsports, drag racing, and high-performance street builds, as it can easily handle modifications that increase power into the four-digit range.
The 2JZ-GTE features a twin-turbo setup, where two smaller turbos work in parallel to provide both fast spool times and higher power potential. The engine is also equipped with oil squirters to cool the pistons, and a stronger crankshaft compared to the naturally aspirated version.
