The 2Jz engine is a well-balanced and powerful engine created by Toyota in the 90's. It was made for the Mark 4 Supra, a car known only for its engine.
Airflow and combustion:
Intake Manifold Design: The intake manifold (a collection of tubes through which the fuel-air mixture flows from the carburetor or fuel injector to the intake valves of the cylinders of an internal combustion engine.) in the 2JZ-GTE is designed to optimize airflow into the cylinders. Runners are tuned for equal length to ensure each cylinder receives a similar air-fuel mixture, promoting smooth power delivery.
Valve Design: The intake and exhaust valves are specifically sized and shaped to optimize airflow at different engine speeds. They may feature larger heads for better flow and lighter materials like titanium for faster actuation at high RPMs.
Combustion Chamber Design: The shape of the combustion chamber plays a crucial role in efficient burning. The 2JZ-GTE's chamber may have a pentroof (In engine design, the penta engine is an arrangement of the upper portion of the cylinder and valves that are common in engines using four valves per cylinder. Among the advantages is a faster burn time of the air-fuel mix.) design, promoting complete combustion and minimizing power loss from unburned fuel.
