The B-series transmission is a popular choice for many performance enthusiasts, particularly those looking to handle upwards of 250 horsepower without incurring excessive costs. Upgrading your B-series transmission can be an effective way to enhance your vehicle’s performance while maintaining reliability. In this article, we will explore various upgrades and modifications that can help you achieve this goal.
Understanding the B-Series Transmission
The B-series transmission, commonly found in Honda vehicles, is known for its lightweight design and robust performance. However, when pushing power levels beyond 250 hp, certain upgrades become necessary to ensure the transmission can handle the increased stress. Understanding the components of the transmission and how they work together is crucial for making informed upgrade decisions.
Key Components to Upgrade
- Clutch Kit: Upgrading to a high-performance clutch kit is essential for handling increased power. Look for options that offer better grip and heat resistance.
- Flywheel: A lightweight flywheel can improve throttle response and reduce rotational mass, making it easier for the engine to rev.
- Transmission Mounts: Upgraded mounts help reduce movement and improve power transfer to the wheels.
- Gear Set: Consider changing the gear ratios for better acceleration and performance, particularly if you’re using the car for racing.
- Short Shifter: A short shifter can provide quicker and more precise gear changes, enhancing the driving experience.
Performance Clutch Options
When upgrading your B-series transmission, the clutch is one of the most critical components to consider. A performance clutch can handle higher torque and provide better engagement. Here are some popular options:
- Exedy Stage 1: Known for its durability and performance, this clutch is suitable for street and mild track use.
- ACT Heavy Duty: This option offers increased clamping force and is ideal for higher horsepower applications.
- Competition Clutch: Offers a range of options for different performance needs, from street to full race.
Lightweight Flywheel Benefits
A lightweight flywheel is an excellent upgrade for improving engine response. By reducing the weight of the flywheel, the engine can rev more freely, translating to better acceleration. Here are some benefits of installing a lightweight flywheel:
- Improved Throttle Response: The engine can rev quicker, allowing for faster acceleration.
- Weight Reduction: Less rotational mass means more efficient power transfer.
- Enhanced Performance: Better engine performance can lead to improved overall vehicle dynamics.
Upgrading Transmission Mounts
Transmission mounts play a crucial role in maintaining the alignment and stability of the transmission. Upgrading to stiffer mounts can help reduce movement during hard acceleration and shifting, which can lead to better power transfer and performance. Here are some options:
- Hasport Motor Mounts: Known for their durability and performance, these mounts are a popular choice among enthusiasts.
- Innovative Mounts: Offers a range of options that provide excellent support and reduce flex.
Choosing the Right Gear Set
The gear set in your B-series transmission can significantly affect performance. Changing the gear ratios can enhance acceleration and improve overall performance, especially for track use. Here are some considerations:
- Final Drive Ratio: A lower final drive ratio can improve acceleration at the expense of top speed.
- Close-Ratio Gears: These gears allow for quicker shifts and keep the engine in its power band more effectively.
Installing a Short Shifter
A short shifter can dramatically improve the driving experience by reducing the distance the shifter needs to travel between gears. This modification can lead to quicker gear changes and a more engaging driving experience. Benefits include:
- Faster Shifts: Reduced shift throw allows for quicker gear changes.
- Improved Feel: A more direct connection to the transmission enhances driver feedback.
Budget-Friendly Upgrade Options
Upgrading your B-series transmission doesn’t have to break the bank. Here are some budget-friendly options to consider:
- Used Components: Look for used or refurbished parts that are still in good condition.
- DIY Installation: If you have the skills, installing upgrades yourself can save on labor costs.
- Local Performance Shops: Sometimes local shops offer package deals that can save you money on multiple upgrades.
Conclusion
Upgrading your B-series transmission to handle 250+ horsepower is achievable without excessive spending. By focusing on key components such as the clutch, flywheel, mounts, gear set, and shifter, you can enhance your vehicle’s performance and reliability. With careful planning and smart choices, you can enjoy the benefits of a high-performance transmission while staying within your budget.
