The SR20DET engine has long been a favorite among car enthusiasts and tuners due to its robust design and performance potential. One of the most popular upgrades for this engine is the installation of a Precision 5858 turbocharger. This article will guide you through the installation process and outline the power expectations you can anticipate from this upgrade.
Understanding the Precision 5858 Turbo
The Precision 5858 turbo is known for its ability to deliver substantial power gains while maintaining reliability. With a compressor wheel diameter of 58mm and a turbine wheel diameter of 58mm, it strikes a balance between spool time and top-end power.
Installation Requirements
Before diving into the installation, it’s important to gather all the necessary tools and components. Here’s a list of what you will need:
- Precision 5858 turbocharger
- Turbo manifold (SR20DET compatible)
- Oil feed and return lines
- Intercooler and piping
- Blow-off valve
- Wastegate (external recommended)
- Fuel injectors (upgraded)
- ECU tuning solution
- Basic hand tools (wrenches, sockets, etc.)
Step-by-Step Installation Process
1. Preparing the Engine Bay
Start by disconnecting the battery and removing any components that obstruct access to the engine. This may include the intake manifold, exhaust manifold, and any heat shields.
2. Removing the Stock Turbo
Once you have access, carefully remove the stock turbocharger. Disconnect the oil feed and return lines, as well as the exhaust and intake piping. Ensure that you keep track of all bolts and gaskets for reinstallation.
3. Installing the Precision 5858 Turbo
Position the Precision 5858 turbo onto the turbo manifold. Secure it with the appropriate bolts and gaskets. Make sure to connect the oil feed line to the turbo and ensure there are no leaks.
4. Setting Up the Intercooler and Piping
Install the intercooler in a suitable location, ensuring it has adequate airflow. Connect the piping from the turbo to the intercooler and then to the intake manifold. This may require custom piping depending on your setup.
5. Installing the Blow-Off Valve and Wastegate
Mount the blow-off valve on the intake piping. This component is crucial for preventing compressor surge. If using an external wastegate, ensure it is plumbed correctly to manage boost pressure effectively.
6. Upgrading Fuel Injectors
To support the increased airflow from the turbo, upgrade your fuel injectors. Ensure they are compatible with your engine and capable of delivering the necessary fuel for your power goals.
7. ECU Tuning
After all components are installed, it’s essential to tune your ECU. This step will optimize fuel delivery and ignition timing to match the new turbo setup, ensuring reliable performance and preventing engine damage.
Power Expectations
With the Precision 5858 turbo installed and properly tuned, you can expect significant power gains from your SR20DET engine. Here are some general expectations:
- Stock SR20DET power: approximately 200-220 hp
- With Precision 5858: potential of 350-450 hp depending on supporting modifications
- Improved torque delivery across the RPM range
Conclusion
Upgrading your SR20DET with a Precision 5858 turbocharger is an excellent way to enhance your vehicle’s performance. By following the installation steps outlined above and ensuring proper tuning, you can enjoy a significant boost in power and overall driving experience. Always remember to monitor your engine’s performance and make adjustments as necessary to maintain reliability.
