Turbocharger Swap Guide for the A80 Supra: Increased Power and Reliability Tips

The A80 Toyota Supra is renowned for its performance and tuning potential, especially when it comes to turbocharger swaps. Upgrading your turbocharger can significantly enhance your vehicle’s power output and reliability. This guide will walk you through the process of swapping a turbocharger in your A80 Supra, providing tips to ensure increased performance and longevity.

Understanding Turbochargers

A turbocharger is a forced induction system that increases the engine’s efficiency and power output by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in greater horsepower. Understanding the types of turbochargers and how they function is essential before starting your swap.

Choosing the Right Turbocharger

Selecting the appropriate turbocharger for your A80 Supra depends on your performance goals and driving style. Here are some key factors to consider:

  • Size: Larger turbos can produce more power but may have a longer spool time.
  • Type: Consider whether you want a journal bearing or ball bearing turbo.
  • Boost Level: Determine the boost levels you aim to achieve.
  • Brand: Research reputable brands known for quality and performance.

Necessary Tools and Equipment

Before starting the turbocharger swap, gather the necessary tools and equipment. Here’s a list of what you’ll need:

  • Socket set and wrenches
  • Screwdrivers (flat and Phillips)
  • Torque wrench
  • Oil catch pan
  • New gaskets and seals
  • Intercooler piping and clamps
  • Boost gauge

Preparation Steps

Proper preparation is essential for a successful turbocharger swap. Follow these steps to ensure a smooth process:

  • Disconnect the Battery: Always disconnect the negative terminal to prevent electrical shorts.
  • Drain Engine Oil: Remove the oil drain plug to prevent spills during the swap.
  • Remove the Intake and Exhaust Components: Take off the intake manifold and exhaust manifold to access the turbocharger.

Removing the Old Turbocharger

With the preparation complete, it’s time to remove the old turbocharger. Follow these steps:

  • Unbolt the exhaust housing from the manifold.
  • Disconnect the oil lines and coolant lines from the turbo.
  • Remove the turbocharger from the engine bay.

Installing the New Turbocharger

Now that the old turbo is out, you can install the new one. Here’s how:

  • Place the new turbocharger in position and secure it to the manifold.
  • Reconnect the oil and coolant lines, ensuring they are tight and leak-free.
  • Reinstall the intake and exhaust components.

Post-Installation Checks

After installation, it’s critical to perform several checks before starting your engine:

  • Check all connections for leaks.
  • Ensure all bolts are torqued to specifications.
  • Install a boost gauge to monitor performance.

Testing and Tuning

Once everything is reassembled, it’s time to start the engine and test the new turbocharger:

  • Start the engine and let it idle for a few minutes.
  • Monitor oil pressure and temperatures closely.
  • Take the car for a test drive, gradually increasing boost levels.

Maintenance Tips for Longevity

To ensure the longevity of your new turbocharger, follow these maintenance tips:

  • Regularly check and change engine oil.
  • Inspect turbo lines for leaks or wear.
  • Keep the air filter clean to prevent debris from entering the turbo.
  • Allow the engine to idle after driving to cool down the turbo.

Conclusion

Swapping the turbocharger in your A80 Supra can lead to significant performance gains and reliability improvements. By following this guide, you can ensure a successful installation and enjoy the enhanced driving experience that comes with increased power.
