Ultimate Guide to Installing a Turbocharger on Your Honda S2000 for Maximum Horsepower Boost
Why Go Turbo?
If you’re a Honda S2000 enthusiast, you’re likely no stranger to the thrill of driving a high-performance car. However, even the most passionate owners often find themselves craving more power and performance from their vehicle. This is where a turbocharger comes into play. A turbo can significantly boost your car’s power output, transforming your naturally aspirated engine into a powerhouse.
“A turbocharger is essentially a turbine-driven forced induction device that compresses air into the engine’s combustion chamber, allowing for a significant increase in power and torque,” explains John Lee, a seasoned mechanic and performance tuner. “For Honda S2000 owners, this can mean going from around 240 horsepower to over 400 horsepower, depending on the setup and tuning.”
Preparing Your Car for the Turbo Install
Before you dive into the installation process, it’s crucial to prepare your car for the added stress and demands of a turbocharged engine.
Engine Health Check
Ensure your engine is in good health. Check for any signs of wear or damage, such as oil leaks, worn piston rings, or damaged cylinder walls. A healthy engine is essential for withstanding the increased pressure and heat generated by a turbocharger.
Upgrading Supporting Components
You’ll need to upgrade several supporting components to handle the increased power and pressure:
- Fuel System: A high-flow fuel pump and fuel injectors are necessary to provide the engine with the additional fuel it needs. A fuel pressure regulator will also be required to maintain the correct fuel pressure[4].
- Exhaust System: A high-flow exhaust system, including a downpipe and cat-back exhaust, is essential for reducing backpressure and allowing the turbo to breathe freely.
- Cooling System: An upgraded cooling system, including a high-performance radiator and intercooler, is vital for managing the increased heat generated by the turbocharger.
- Oil System: Ensure your oil system can handle the increased heat and pressure. This may involve upgrading to a high-performance oil pump and oil cooler.
Choosing the Right Turbo Kit
Selecting the right turbo kit is a critical step in your installation process. Here are some key factors to consider:
Turbo Kit Manufacturer
Look for reputable manufacturers known for their quality and performance. Brands like HKS, Garrett, and Precision Turbo offer a range of turbo kits specifically designed for the Honda S2000.
Turbo Size and Type
The size and type of turbo you choose will depend on your performance goals. A smaller turbo will provide quicker spooling but may not offer the same peak power as a larger turbo. Common turbo sizes for the S2000 include the GT28, GT30, and GT35.
Kit Components
Ensure the kit includes all necessary components, such as:
- Turbocharger
- Manifold
- Downpipe
- Intercooler
- Piping and fittings
- Fuel system upgrades
- ECU tuning software
Here is a detailed list of what you should look for in a turbo kit:
- Turbocharger: The heart of the kit, responsible for compressing air into the engine.
- Manifold: Directs exhaust gases to the turbocharger.
- Downpipe: Connects the turbocharger to the exhaust system.
- Intercooler: Cools the compressed air before it enters the engine.
- Piping and Fittings: Necessary for connecting all components.
- Fuel System Upgrades: Includes a high-flow fuel pump, fuel injectors, and fuel pressure regulator.
- ECU Tuning Software: Essential for adjusting engine settings to work optimally with the turbocharger.
Installation Process
The installation process can be complex and is best handled by a professional mechanic or an experienced DIY enthusiast. Here’s a general overview of the steps involved:
Step 1: Engine Preparation
Disconnect the battery and drain the cooling system. Remove the intake manifold, exhaust manifold, and any other components that will interfere with the installation.
Step 2: Installing the Turbocharger
Mount the turbocharger to the engine block using the provided manifold. Ensure all connections are secure and properly sealed.
Step 3: Installing the Downpipe and Exhaust System
Install the downpipe and connect it to the exhaust system. Ensure all connections are secure and there are no leaks.
Step 4: Installing the Intercooler
Mount the intercooler in the front of the car and connect the piping to the turbocharger and intake manifold.
Step 5: Upgrading the Fuel System
Install the high-flow fuel pump, fuel injectors, and fuel pressure regulator. Ensure all connections are secure and properly sealed.
Step 6: ECU Tuning
Use the provided ECU tuning software to adjust engine settings for optimal performance with the turbocharger. This includes adjusting fuel injection timing, ignition timing, and boost pressure.
Here is a comprehensive table comparing some popular turbo kits for the Honda S2000:
| Turbo Kit | Turbo Size | Power Output | Spool Time | Price Range |
|---|---|---|---|---|
| HKS GT28 | GT28 | 350-400 HP | Quick | $3,000 – $4,000 |
| Garrett GT30 | GT30 | 400-500 HP | Medium | $4,000 – $5,500 |
| Precision GT35 | GT35 | 500-600 HP | Slow | $5,500 – $7,000 |
Tuning and Performance
Once the installation is complete, tuning your engine is crucial for optimal performance and reliability.
Engine Tuning
Work with a professional tuner to adjust engine settings such as fuel injection timing, ignition timing, and boost pressure. This ensures the engine runs smoothly and efficiently under the increased stress of the turbocharger.
Performance Testing
Take your car for a spin to test its performance. Pay attention to how the car responds to different RPM ranges and boost levels. Make any necessary adjustments to the tuning settings based on your observations.
Maintenance and Upkeep
To ensure your turbocharged engine remains in top condition, regular maintenance is essential.
Oil Changes
Regular oil changes are crucial for maintaining the health of your engine. Use high-performance oil that can handle the increased heat and pressure generated by the turbocharger.
Coolant Checks
Regularly check the coolant level and condition to ensure the cooling system is functioning properly.
Boost Pressure Monitoring
Monitor boost pressure regularly to ensure it remains within the recommended range. High boost pressure can lead to engine damage if not managed properly.
Installing a turbocharger on your Honda S2000 is a significant undertaking but can yield incredible results in terms of power and performance. By preparing your car, choosing the right turbo kit, following a detailed installation process, and tuning your engine, you can unlock the full potential of your vehicle.
“Going turbo is a game-changer for any car enthusiast,” says Mark Davis, owner of a turbocharged S2000. “The boost in power and torque is exhilarating, and with proper maintenance, it can be a reliable and enjoyable upgrade.”
Whether you’re a seasoned mechanic or a DIY enthusiast, the journey to turbocharging your Honda S2000 is one that requires patience, dedication, and a passion for performance. With the right guidance and tools, you can transform your car into a high-performance machine that delivers an unforgettable driving experience.
