The 2JZ-FSE is a variant of the legendary 2JZ engine family from Toyota, known for its durability and performance. While most enthusiasts are familiar with the turbocharged 2JZ-GTE used in the Toyota Supra, the 2JZ-FSE is an inline-6 naturally aspirated engine designed with an emphasis on fuel efficiency and lower emissions through Direct Fuel Injection (D-4 technology).
Here are the specifications for the 2JZ-FSE:
Engine Specifications:
Engine Code: 2JZ-FSE
Type: Inline-6, Dual Overhead Camshaft (DOHC), 24-valve
Displacement: 2,997 cc (3.0 liters)
Bore x Stroke: 86.0 mm x 86.0 mm (square engine configuration)
Compression Ratio: 11.3:1
Fuel System: Direct Fuel Injection (D-4 technology)
Fuel Type: Petrol (unleaded, premium recommended)
Valve Timing: Variable Valve Timing with Intelligence (VVT-i)
Power Output:
217 hp (162 kW) at 5,600 rpm
Torque:
294 Nm (217 lb-ft) at 3,600 rpm
Drivetrain: Rear-wheel drive (RWD)
Notable Features:
D-4 Direct Injection: The 2JZ-FSE uses Toyota’s D-4 direct injection technology, which is aimed at improving fuel efficiency and reducing emissions. The fuel is injected directly into the combustion chamber, resulting in more complete combustion, especially under load. This engine was designed to meet stricter emission standards while maintaining respectable power output.
Fuel Efficiency: Compared to the high-performance 2JZ-GTE, the 2JZ-FSE focuses on a balance between performance and efficiency, making it suitable for luxury sedans like the Toyota Crown and the Toyota Aristo (also known as the Lexus GS in some markets).
VVT-i Technology: Toyota’s Variable Valve Timing with intelligence (VVT-i) allows for optimized timing of the intake valves, improving both power and efficiency across the RPM range.
Applications:
The 2JZ-FSE was primarily used in Toyota’s larger luxury sedans and sports sedans, such as:
Toyota Crown (S170 and S180 series)
Toyota Aristo (JZS160), also known as the Lexus GS in some markets.
Performance and Characteristics:
Power Delivery: The 2JZ-FSE delivers smooth and linear power, with the focus on torque in the mid-range for better drivability and comfort in urban and highway settings.
Reliability: Like other 2JZ engines, the 2JZ-FSE is known for its durability and long lifespan, but its design places more emphasis on refinement and efficiency rather than raw performance like the 2JZ-GTE.
Fuel Economy:
The 2JZ-FSE is generally more fuel-efficient than its 2JZ-GTE counterpart, providing around 9-11 km/L (combined cycle), though actual figures may vary depending on the vehicle and driving conditions.
In summary, the 2JZ-FSE is a refined, naturally aspirated inline-6 engine designed to offer a balance of power, fuel efficiency, and reduced emissions, making it well-suited for luxury sedans. Its direct injection and VVT-i technology provide a smooth and responsive driving experience while maintaining Toyota’s famous reliability.
