Understanding B16 Cylinder Heads
What is a B16 Head?
The B16 head is part of Honda’s B-series engine family, primarily used in the Civic and Integra models. It features a DOHC (Dual Overhead Cam) design with VTEC (Variable Valve Timing and Lift Electronic Control) technology, allowing for improved performance across various RPM ranges. This head is known for its ability to produce high horsepower while maintaining reliability.
Why Upgrade to a B16 Head?
Upgrading to a B16 head can significantly enhance your vehicle’s performance. These heads are designed to optimize airflow and combustion efficiency, resulting in increased horsepower and torque. They are also lightweight, which contributes to better acceleration and handling. For serious tuners, a high-performance B16 head can be the difference between a good build and a great one.
Features of B16 Heads
Material and Construction
B16 heads are typically made from high-quality aluminum, which offers a great balance of weight and strength. The construction involves precise machining to ensure smooth airflow through the intake and exhaust ports. Some aftermarket options, like those from 4pistonracing.com, utilize CNC technology for even greater precision.
VTEC Technology
The VTEC system is one of the standout features of the B16 head. It allows for variable timing and lift of the intake valves, effectively switching between a low-lift cam profile for efficiency and a high-lift profile for performance. This technology enables drivers to enjoy better fuel economy during regular driving and increased power during aggressive driving.
Porting and Polishing
Many enthusiasts opt for porting and polishing their B16 heads to improve airflow. This process involves removing material from the intake and exhaust ports to create a smoother path for air and exhaust gases. Aftermarket companies like KS Performances offer fully built packages that include this essential modification, ensuring optimal performance.
