Toyota 2JZ Engine Specs
Here in this article you will learn about the Toyota 2JZ Engine Specs , Performance, Cylinder Heads, Cam Specs & More, Let’s discuss the ford Toyota 2JZ Engine Specs , Valvetrain, performance, and Reviews.
The 2JZ engine was made from 1991 until 2007.
It’s a 3.0-liter inline six-cylinder gasoline engine. It is among the most renowned Toyota engines, notably the twin-turbo 2JZ engine that is that was used in the legendary Toyota Supra.
A popular engine version is 2GZ-GE, a machine with naturally occurring aspiration frequently used in Toyota’s and Lexus’s vehicles (such as Toyota Altezza, Aristo, Soarer, Lexus IS300, GS300 as well as SC300).
It is well-known for its quality and durability.
The overall structure 2JZ’s general structure 2JZ has a similar design to that of the 1JZ. However, it’s not an accessible, stroked version.
Cylinder blocks are constructed from cast iron which is challenging and durable.
The engine block of 2JZ is higher than the 1JZ engine block because of the increased stroke of 14.5mm (0.57 in.).
The 2GZ-GE’s initial generation featured an aluminum cylinder head with an easy-to-use design, four valves for each cylinder with centrally located spark plugs, and double overhead camshafts driven by belts.
The diameter of the intake valve is 33.5 millimeters, and the diameter of the exhaust valve is 29.0 millimeters.
Camshaft Specifications: duration – 233/236 deg (intake/exhaust), valve lift 8.26/8.41 mm (intake/exhaust).
The engine was fitted with a traditional ignition system that included an ignition distributor and one coil.
The intake consists of an aluminum intake manifold and Toyota’s ACIS system.
Naturally, aspirated 2JZ comes with a 10.5:1 compression ratio.

Toyota 2JZ Engine Specs FAQ
What are the specs on a 2JZ engine?
The 2JZ-GE is a standard version. The output ranges from 215-230 PS (158-169 kW 212-227 BHP) between 5800 and 6000 rpm.
It also produces 220-220 pounds (283-298 Nm) of torque from 4800 to 5800 RPM.
It uses Sequential Electronic Fuel Injection, which includes an aluminum head and four valves per cylinder, with a cast iron cylinder block.
How much horsepower does a 2JZ engine have?
The 2JZ-GTE is the 320hp above, which is surprisingly low, and 315 lb-ft of torque on North American-bound models.
And there’s a reason why that things appear so tame. Since 1989, Japanese automakers have avoided costly horsepower battles by limiting production-car output in Japan to 276 horsepower.
What is so special about 2JZ engines?
Its 2JZ engine can be described as a revered engine in the tuner community, which is why the year that ended, the Supra was so well-known.
The highly engineered, closed engine design permits the use of vast levels of boost in the internals of the stock engine.
Is 2JZ the best engine ever built?
It is a Japanese manufacturer well-known for its significant engines through the decades. However, the unique one is the famous 2JZ.
The most potent six-cylinder engine ever built, The 2JZ is so well-constructed that, with just a few tweaks, it could produce massive quantities of power.
