Preparing for the Installation
Before diving into the installation, it’s crucial to gather all necessary tools and components. Here’s a checklist to prepare:
- Garrett GTX2860R Turbocharger
- Turbo manifold
- Wastegate
- Oil feed and drain lines
- Intercooler and piping
- ECU tuning software
- Basic hand tools (wrenches, sockets, etc.)
Installation Steps
Step 1: Remove the Stock Components
Start by disconnecting the battery and removing the stock air intake system. Next, detach the exhaust manifold and turbocharger from the engine. This step may require some patience, as rusted bolts can be challenging to remove.
Step 2: Install the Turbo Manifold
Once the stock components are removed, install the new turbo manifold. Ensure that the manifold is properly aligned and securely fastened to prevent any exhaust leaks.

With the manifold in place, mount the Garrett GTX2860R turbocharger. Use the supplied hardware to secure the turbo to the manifold. Make sure to check for proper alignment to avoid any potential issues.
Step 4: Connect Oil Lines
Next, connect the oil feed and drain lines to the turbocharger. Proper oil lubrication is essential for the longevity of the turbo, so ensure all connections are tight and leak-free.
Step 5: Install the Intercooler
Install the intercooler and connect the piping from the turbo to the intercooler and from the intercooler to the intake manifold. This step is crucial for maintaining optimal air temperatures and enhancing performance.
Step 6: ECU Tuning
After all components are installed, it’s essential to tune the ECU. This step ensures the engine runs efficiently with the new turbo setup. Use appropriate tuning software to adjust fuel maps and ignition timing.
Performance Review
After completing the installation and tuning, it’s time to evaluate the performance of the Mazda Miata with the Garrett GTX2860R turbocharger. Here are some key performance metrics observed:
- Power Increase: Up to 250 HP at the wheels
- Torque Increase: 220 lb-ft
- Boost Response: Spools quickly around 2500 RPM
- Top Speed: Increased acceleration and higher top speed capabilities
Conclusion
The Garrett GTX2860R turbocharger is an excellent upgrade for Mazda Miata enthusiasts looking to enhance performance.
