The Toyota MR2 SW20 is a beloved sports car known for its mid-engine layout and agile handling. For enthusiasts looking to boost performance, installing a TurboXS downpipe can yield significant power gains, often around 50 horsepower. This article will guide you through the benefits of this modification and the installation process.
Understanding the SW20 Turbo System
The SW20 model of the Toyota MR2 came equipped with a turbocharged engine that provides a solid foundation for performance upgrades. The turbo system works by forcing more air into the engine, allowing for more fuel to be burned, thus increasing power output.
Benefits of Upgrading to a TurboXS Downpipe
Upgrading to a TurboXS downpipe offers several advantages for MR2 enthusiasts:
- Increased Horsepower: Expect gains of up to 50 HP with proper tuning.
- Improved Exhaust Flow: A larger diameter downpipe reduces back pressure.
- Enhanced Turbo Response: Better airflow leads to quicker spool times.
- Weight Reduction: Aftermarket downpipes are often lighter than stock components.
Installation Process
Installing a TurboXS downpipe requires some mechanical knowledge and the right tools. Here’s a step-by-step guide to help you through the process:
Tools and Materials Needed
- TurboXS downpipe
- Socket set
- Wrenches
- Torque wrench
- Jack and jack stands
- Exhaust gasket
- Safety goggles and gloves
Step-by-Step Installation
Follow these steps to install the TurboXS downpipe:
- 1. Prepare the Vehicle: Start by parking the MR2 on a flat surface. Use a jack to lift the rear of the car and secure it with jack stands.
- 2. Remove the Stock Downpipe: Disconnect the exhaust from the turbocharger, and unbolt the stock downpipe from the exhaust system. Be cautious of any remaining exhaust gases.
- 3. Install the TurboXS Downpipe: Position the TurboXS downpipe in place and secure it using the provided hardware. Ensure the exhaust gasket is properly aligned.
- 4. Reconnect the Exhaust: Bolt the exhaust back onto the downpipe and ensure all connections are tight.
- 5. Lower the Vehicle: Carefully remove the jack stands and lower the car back to the ground.
- 6. Test the Installation: Start the engine and check for any leaks in the exhaust system. Listen for any unusual noises.
Tuning for Maximum Performance
After installing the TurboXS downpipe, it’s essential to tune your engine to take full advantage of the increased airflow. A proper tune can optimize fuel maps and ignition timing, ensuring your MR2 runs efficiently and safely.
Choosing a Tuning Method
- ECU Reflash: A popular method that modifies the stock ECU settings.
- Standalone Engine Management: Offers complete control over engine parameters.
- Piggyback Systems: Adds additional tuning capabilities without replacing the stock ECU.
