The world of automotive performance is filled with choices, especially when it comes to engine swaps and upgrades. For Honda enthusiasts, the D-series engine has been a popular choice for many years. However, many wonder if upgrading to a B16B head is worth the investment. In this article, we will explore the power gains associated with this upgrade and provide a cost analysis for those considering a D-series swap.
Understanding the D-Series Engine
The D-series engine family has been a staple in Honda’s lineup since the late 1980s. Known for its reliability and efficiency, it has been used in various models, including the Civic and CRX. The D-series engines are typically characterized by their SOHC (Single Overhead Cam) configuration, which limits their performance potential compared to DOHC (Double Overhead Cam) engines.
What is the B16B Head?
The B16B head comes from the Honda Civic Type R, specifically designed for high performance. This head features a DOHC configuration, larger valves, and improved airflow characteristics compared to the D-series head. The B16B is known for its ability to produce higher horsepower and torque figures, making it an attractive option for those looking to enhance their D-series engine.
Power Gains from Upgrading to a B16B Head
One of the primary reasons to consider upgrading to a B16B head is the potential for significant power gains. Here are some key points to consider:
- Increased Horsepower: Upgrading to a B16B head can yield an increase of 20-40 horsepower, depending on supporting modifications.
- Improved Torque: The B16B head can also enhance torque delivery, providing a more responsive driving experience.
- Better Airflow: The design of the B16B head allows for better airflow, which is crucial for maximizing engine performance.
- Higher RPM Capability: The B16B head is engineered for higher RPMs, allowing for a broader power band.
Cost Analysis of Upgrading to a B16B Head
While the power gains are enticing, it is essential to consider the costs associated with the upgrade. Here’s a breakdown of the potential expenses:
- B16B Head Cost: The cost of a used B16B head can range from $500 to $1,200, depending on condition and availability.
- Additional Parts: You may need to purchase additional parts such as gaskets, bolts, and possibly a new intake manifold, which can add another $200 to $500.
- Labor Costs: If you’re not performing the swap yourself, labor costs can range from $300 to $800, depending on the shop’s rates.
- Tuning Costs: After the upgrade, proper tuning is essential, which can cost an additional $200 to $500.
Supporting Modifications for Maximum Gains
To truly maximize the benefits of a B16B head upgrade, consider the following supporting modifications:
- Performance Camshafts: Upgrading camshafts can further enhance airflow and improve performance.
- High-Performance Intake and Exhaust: A free-flowing intake and exhaust system will complement the head upgrade.
- ECU Tuning: Custom tuning will ensure that your engine runs optimally with the new head.
- Upgraded Fuel System: Ensuring adequate fuel delivery is critical for maximizing power gains.
Conclusion: Is It Worth It?
Upgrading to a B16B head can provide significant power gains for D-series engine enthusiasts. However, it is essential to weigh the costs against the potential benefits. If you are looking for a substantial increase in performance and are willing to invest in supporting modifications, the upgrade may be worth it. Ultimately, it depends on your performance goals and budget.
