Head and Valvetrain Specs J30A3

The Honda J30A3 engine features a DOHC (Double Overhead Camshaft) valvetrain design, which means that it has two camshafts in the engine head. This design helps to provide efficient and precise control of the engine valves, which in turn allows for improved engine performance.

The J30A3 engine has four valves per cylinder, with a total of 24 valves in the engine. This provides ample airflow into the engine, contributing to the engine’s overall power output.

The engine also features VTEC (Variable Valve Timing and Lift Electronic Control), which allows for the engine to switch between two different cam profiles based on engine RPM. This results in improved engine performance and efficiency throughout the entire RPM range.

In terms of head material, the Honda J30A3 engine features an aluminum cylinder head, which helps to reduce the engine’s overall weight and improve cooling.

The use of an aluminum head also allows for improved engine responsiveness, as it is able to transfer heat away from the combustion chamber more efficiently than other materials.

In conclusion, the Honda J30A3 engine features a DOHC valvetrain design with 24 valves and VTEC technology. The engine’s aluminum cylinder head provides improved engine performance, cooling, and responsiveness.
