Understanding the Stock Turbocharger
The stock turbocharger on the Mitsubishi 3000GT is designed to provide a balance between performance and reliability. However, as power enthusiasts seek more from their vehicles, the limitations of the stock turbo become apparent. The stock unit is capable of producing adequate boost but often falls short for those looking for significant power gains.
Benefits of Upgrading to the GT35R
Upgrading to the GT35R turbocharger offers numerous advantages:
- Increased Horsepower: The GT35R can provide an additional 70+ horsepower, significantly enhancing the vehicle’s performance.
- Improved Boost Response: The GT35R is designed for quicker spool times, allowing for better throttle response.
- Enhanced Efficiency: This turbocharger offers improved airflow and efficiency, maximizing the engine’s potential.
- Customization: The GT35R allows for various tuning options, enabling drivers to tailor their performance to their preferences.
Preparing for the Swap
Before diving into the turbocharger swap, preparation is key. Here are the essential steps to ensure a smooth transition:
- Gather Necessary Tools: Make sure you have the right tools, including wrenches, sockets, and screwdrivers.
- Purchase Required Parts: In addition to the GT35R turbocharger, consider acquiring a new wastegate, downpipe, and supporting modifications.
- Consult Resources: Utilize online forums and guides for insights and tips from other 3000GT owners who have completed similar swaps.
The Turbocharger Swap Process
Now that you’re prepared, let’s delve into the step-by-step process of swapping the stock turbocharger for the GT35R:
- 1. Remove the Stock Turbocharger: Begin by disconnecting the battery, then remove the intake piping, exhaust manifold, and any associated fittings to access the stock turbo.
- 2. Install the GT35R: Position the GT35R in place of the stock unit. Ensure all connections are secure and properly aligned.
- 3. Upgrade Supporting Components: Install the new wastegate and downpipe, ensuring that all components are compatible with the GT35R.
- 4. Reconnect Everything: Reattach the intake piping and any other components that were removed during the process.
- 5. Tune the Engine: After installation, it’s crucial to have the engine tuned to accommodate the new turbocharger. This will optimize performance and prevent engine damage.
Cost Breakdown
When considering the turbocharger swap, it’s essential to understand the costs involved. Here’s a breakdown:
- GT35R Turbocharger: Approximately $1,500
- Wastegate: Around $300
- Downpipe: Approximately $400
- Miscellaneous Parts: Estimated $300 (gaskets, fittings, etc.)
Potential Challenges
While the turbocharger swap can yield impressive results, there are potential challenges to consider:
- Compatibility Issues: Ensure that all parts are compatible with your specific 3000GT model.
- Tuning Complexity: Proper tuning is essential; consider consulting a professional if you are unfamiliar with tuning procedures.
- Heat Management: The increased power can lead to higher temperatures; ensure your cooling system is up to the task.
