The Honda Prelude has long been a favorite among car enthusiasts, known for its sleek design and impressive handling. However, for those looking to take their Prelude to the next level, forced induction is a game-changer. In this article, we will explore the installation of a BorgWarner EFR turbo kit, which can add over 200 horsepower to your vehicle.
Understanding Forced Induction
Forced induction refers to the process of forcing more air into the engine’s combustion chamber than would normally enter under atmospheric pressure. This results in a denser air-fuel mixture, leading to increased power output. There are two main types of forced induction: supercharging and turbocharging. In this article, we will focus on turbocharging, specifically the BorgWarner EFR turbo kit.
Benefits of the BorgWarner EFR Turbo Kit
The BorgWarner EFR turbo kit offers several advantages for Honda Prelude owners:
- Increased Power: The kit can provide an additional 200+ horsepower, transforming your Prelude’s performance.
- Improved Efficiency: Turbocharging can lead to better fuel efficiency compared to naturally aspirated engines.
- Lightweight Design: The EFR series is designed to be lightweight, reducing overall vehicle weight and improving handling.
- Enhanced Responsiveness: The turbo’s advanced technology allows for quicker spool times, providing power when you need it.
Preparing for Installation
Before diving into the installation process, it’s essential to gather the necessary tools and materials. Here’s a list of what you’ll need:
- Basic hand tools (wrenches, sockets, screwdrivers)
- Torque wrench
- Jack and jack stands
- New gaskets and seals
- Oil and coolant
- Boost controller (optional)
Installation Steps
Step 1: Prepare the Vehicle
Begin by safely lifting the vehicle using a jack and jack stands. Ensure that you have enough space to work comfortably around the engine bay.
Step 2: Remove the Stock Components
Next, remove the stock intake manifold, exhaust manifold, and any other components blocking access to the turbo installation area. Be sure to label and organize bolts and parts for easy reassembly.
Step 3: Install the Turbo Kit
With the stock components removed, it’s time to install the BorgWarner EFR turbo kit. Follow these steps:
- Attach the turbo to the provided manifold, ensuring all gaskets are correctly positioned.
- Secure the turbo using the supplied hardware, following the manufacturer’s torque specifications.
- Connect the oil feed and return lines to the turbo, ensuring there are no leaks.
- Install the new intake and exhaust piping included in the kit.
Step 4: Reassemble the Engine Bay
Once the turbo is securely in place, reattach the intake manifold and any other components you previously removed. Make sure to double-check all connections and fittings.
Step 5: Configure the Boost Controller
If you opted to install a boost controller, now is the time to configure it. Follow the manufacturer’s instructions for proper setup to ensure optimal performance.
Step 6: Final Checks and Testing
Before starting the engine, perform a final inspection of all connections, ensuring everything is secure. Once you’re satisfied, start the engine and check for any leaks or unusual noises. Allow the engine to warm up and monitor the boost levels.
Tuning Your Honda Prelude
After installing the turbo kit, tuning is essential to maximize performance and ensure engine longevity. Consider the following options:
- ECU Reflash: Update the engine’s computer to accommodate the increased airflow and fuel demands.
- Dyno Tuning: Take your vehicle to a professional for a custom dyno tune, ensuring optimal performance and reliability.
- Monitoring Tools: Install gauges to monitor boost levels, air-fuel ratios, and engine temperatures.
Maintenance Tips
Maintaining your turbocharged Honda Prelude is crucial for longevity and performance. Here are some tips to keep in mind:
- Regularly check and change the engine oil, especially after the initial break-in period.
- Inspect the turbo and its components for wear and tear, replacing parts as necessary.
- Monitor boost levels and engine performance to catch any issues early.
- Keep the cooling system in good condition to prevent overheating.
Conclusion
Installing a BorgWarner EFR turbo kit in your Honda Prelude can significantly enhance its performance, providing an exhilarating driving experience. By following the proper installation steps and maintaining your vehicle, you can enjoy the benefits of forced induction for years to come. Whether you’re a seasoned enthusiast or a newcomer to the world of turbocharging, this upgrade is sure to impress.
