The Honda Prelude is a beloved sports coupe that has captured the hearts of enthusiasts for decades. One of the most exciting modifications that can be done to a Prelude is the turbo swap, which can significantly increase horsepower and performance. In this guide, we will explore the steps involved in a turbo swap, the associated costs, and the potential gains in horsepower.
Understanding the Honda Prelude Turbo Swap
A turbo swap involves replacing the factory engine components with a turbocharged system. This modification can yield over 100 horsepower gains, transforming the Prelude into a formidable performance machine. Before diving into the steps, it is essential to understand the components required for a successful turbo swap.
Essential Components for Turbo Swap
- Turbocharger
- Intercooler
- Turbo manifold
- Wastegate
- Blow-off valve
- Fuel injectors
- ECU tuning
- Exhaust system
- Oil lines and fittings
- Boost controller
Steps to Perform a Turbo Swap
Step 1: Gather Necessary Tools and Parts
Before starting the swap, ensure you have all the necessary tools and parts. This includes wrenches, sockets, screwdrivers, and any specific tools for your Prelude model.
Step 2: Remove the Existing Engine Components
Begin by disconnecting the battery and removing the intake manifold, exhaust manifold, and any other components that will obstruct the installation of the turbo kit. Make sure to label and store all parts safely.
Step 3: Install the Turbo Manifold
Install the turbo manifold onto the engine block. Ensure that all bolts are tightened to the manufacturer’s specifications to prevent leaks.
Step 4: Mount the Turbocharger
Next, mount the turbocharger onto the manifold. Use proper gaskets and hardware to ensure a secure fit. Pay attention to the orientation of the turbo for optimal performance.
Step 5: Install the Intercooler and Piping
Install the intercooler in a suitable location, typically in front of the radiator. Connect the piping from the turbo to the intercooler and from the intercooler to the intake manifold. Ensure all connections are tight and leak-free.
Step 6: Set Up the Fuel System
Upgrade the fuel injectors to support the increased airflow and power. Install any necessary fuel pumps and regulators to maintain proper fuel pressure. This step is crucial for achieving optimal performance.
Step 7: ECU Tuning
After all hardware is installed, it is essential to tune the ECU to accommodate the turbo setup. This may involve using a standalone ECU or reflashing the stock ECU. Proper tuning ensures that the engine runs efficiently and safely under boost.
Step 8: Final Checks and Testing
Before starting the engine, double-check all connections, bolts, and components. Once everything is secure, reconnect the battery and start the engine. Monitor for any leaks or unusual noises during the initial startup.
Cost Breakdown for Turbo Swap
The cost of a turbo swap can vary significantly based on the components chosen and whether you perform the installation yourself or hire a professional. Below is a general breakdown of potential costs:
- Turbocharger: $500 – $2,000
- Intercooler: $200 – $800
- Manifold: $200 – $600
- Wastegate: $100 – $300
- Fuel injectors: $200 – $600
- ECU tuning: $300 – $1,000
- Miscellaneous parts (hoses, fittings, etc.): $100 – $500
- Labor (if applicable): $500 – $1,500
Potential Gains in Horsepower
With a proper turbo swap, Honda Prelude owners can expect to see significant horsepower gains. Depending on the setup and tuning, gains of over 100 horsepower are achievable. This increase can transform the driving experience, providing exhilarating acceleration and performance.
Conclusion
The Honda Prelude turbo swap is an exciting project for enthusiasts looking to enhance their vehicle’s performance. By following the outlined steps and understanding the costs involved, you can successfully achieve impressive horsepower gains. Always remember to prioritize safety and proper tuning for the best results.
