The Honda B-series engine has long been a favorite among car enthusiasts for its reliability and performance potential. With the right modifications, you can significantly boost its power output. This article explores how to achieve a 250 horsepower output from a 2.0L B-series engine on a budget of $3,000.
Understanding the Honda B-Series Engine
The Honda B-series engine family includes several variants, but the B20B and B20Z are popular choices for turbo swaps. These engines are known for their robust construction and ability to handle increased boost pressure.
Key Features of the B-Series
- Aluminum DOHC design
- High revving capability
- Aftermarket support with numerous performance parts
Setting a Budget
To achieve your goal of boosting power from 160 to 250 hp, careful budgeting is essential. Here’s a breakdown of potential costs:
- Turbocharger: $1,000
- Intercooler: $500
- Fuel system upgrades: $600
- Tuning: $400
- Miscellaneous (pipes, gaskets, etc.): $500
Choosing the Right Turbocharger
Selecting the right turbocharger is crucial for achieving your desired horsepower without compromising reliability. Look for a turbo that provides a balance of spool time and boost pressure.
Recommended Turbochargers
- Garrett GT28
- Precision 5858
- Holset HX35
Upgrading the Fuel System
To support the increased power, you will need to upgrade your fuel system. This includes larger fuel injectors, a high-flow fuel pump, and possibly a fuel pressure regulator.
Fuel System Components
- Fuel injectors: 450cc or larger
- High-flow fuel pump (e.g., Walbro 255)
- Adjustable fuel pressure regulator
Installing the Intercooler
An intercooler is essential for cooling the intake air, which improves performance and prevents detonation. Choose a front-mount intercooler for optimal airflow.
Intercooler Installation Tips
- Ensure proper piping for airflow
- Mount securely to avoid damage
- Check for leaks after installation
Tuning Your Engine
After installing the turbo and supporting modifications, tuning is necessary to optimize performance. A proper tune will ensure the engine runs efficiently and reliably at higher power levels.
Tuning Options
- Standalone engine management systems
- Reflashing the stock ECU
- Using a piggyback system
Final Considerations
Boosting your Honda B-series engine from 160 to 250 hp on a $3,000 budget is achievable with careful planning and the right components. Focus on quality parts and reliable tuning to ensure your engine performs at its best.
