Installation Process
Installing a PTE 6266 turbo on your SRT-4 requires careful planning and execution. Below is a step-by-step guide to ensure a smooth installation.
Tools and Materials Needed
- Socket set
- Wrenches
- Torque wrench
- New gaskets
- Oil feed and drain lines
- Intercooler piping
- ECU tuning software
Step-by-Step Installation
Follow these steps to replace your existing turbo with the PTE 6266:
- Disconnect the battery to prevent any electrical issues.
- Remove the factory turbo and exhaust manifold.
- Install the new gaskets on the exhaust manifold.
- Attach the PTE 6266 turbo to the exhaust manifold.
- Connect the oil feed and drain lines to the turbo.
- Install the intercooler piping, ensuring all connections are secure.
- Reattach the intake and any other components removed during the process.
- Reconnect the battery.
Tuning Your SRT-4 for Maximum Performance
Once the installation is complete, tuning your SRT-4 is critical to maximize the performance of the PTE 6266 turbo. Here are some essential tuning tips:
ECU Tuning Options
- Standalone ECU: Provides complete control over fuel and timing.
- Reflash: Modify the stock ECU with performance maps.
- Piggyback systems: Work alongside the stock ECU for tuning adjustments.
Air-Fuel Ratio (AFR) Tuning
Maintaining the correct air-fuel ratio is crucial for engine health and performance. Aim for an AFR of 11.5 to 12.0 during wide-open throttle (WOT) conditions.
Boost Control
- Use a boost controller to manage boost levels effectively.
- Monitor boost levels during tuning to avoid overboost conditions.
Common Issues and Troubleshooting
After upgrading, you may encounter some common issues. Here’s how to troubleshoot them:
Boost Leaks
Check all connections in the intake and intercooler piping for leaks, as they can significantly affect performance.
Oil Starvation
Ensure that the oil feed and drain lines are correctly installed to prevent oil starvation, which can damage the turbo.
ECU Error Codes
Monitor the ECU for any error codes that may indicate tuning or installation issues. Use a diagnostic tool to read and clear codes as needed.
Conclusion
Upgrading your SRT-4 turbo to a PTE 6266 can significantly enhance your vehicle’s performance, allowing you to achieve over 500 horsepower. By following the installation and tuning tips outlined in this article, you can ensure a successful upgrade that maximizes your car’s potential.
