Preparation Steps
Before starting the installation, it’s essential to prepare your workspace and gather all necessary tools and materials. Make sure your vehicle is on a level surface and securely lifted if needed.
1. Remove the Existing Engine
Begin by disconnecting the battery and draining the fluids from the existing engine. Remove the intake and exhaust components, electrical connections, and any other parts that may hinder engine removal.
2. Install the Blitz LM Intercooler
With the old engine out, it’s time to install the Blitz LM intercooler. Follow the manufacturer’s instructions for mounting and connecting the intercooler to the intake and turbocharger.
Installing the SR20DET Engine
Now that the intercooler is in place, you can proceed with the installation of the SR20DET engine. Make sure to have an engine hoist ready for this step.
1. Position the Engine
Carefully position the SR20DET engine over the engine bay using the hoist. Align it with the engine mounts and ensure that it is secure before lowering it into place.
2. Secure the Engine
Once the engine is in place, secure it to the mounts using the appropriate bolts. Ensure that everything is tightened to the manufacturer’s specifications using a torque wrench.
Connecting Components
After the engine is secured, you’ll need to connect various components to ensure proper functionality.
1. Connect the Intercooler Piping
Attach the intercooler piping to the turbocharger and the intake manifold. Make sure all connections are secure and leak-free.
2. Install the Fuel System
Upgrade the fuel pump if necessary and connect the fuel lines to the engine. Ensure that all connections are tight and free of leaks.
3. Electrical Connections
Reconnect the electrical harness to the engine. Pay attention to sensor connections and ensure that everything is properly wired.
Final Steps
With all components connected, it’s time to finalize the installation.
1. Fill Fluids
Fill the engine with oil and coolant. Check all fluid levels to ensure proper operation.
2. ECU Tuning
Use ECU tuning software to adjust the engine settings for optimal performance. This step is crucial for achieving the desired 350 horsepower.
3. Start the Engine
Once everything is connected and fluids are filled, start the engine. Monitor for any leaks or issues and ensure that the engine runs smoothly.
Testing and Tuning
After installation, it’s important to conduct thorough testing and tuning to ensure your SR20DET is performing as expected.
1. Dyno Testing
Take your vehicle to a dyno facility to measure horsepower and torque. This will help you verify that you’ve reached your target of 350 horsepower.
2. Road Testing
Perform road tests to assess the vehicle’s performance. Pay attention to throttle response, boost levels, and overall drivability.
Conclusion
The SR20DET swap, when done correctly, can significantly enhance your vehicle’s performance. By following this step-by-step guide and using a Blitz LM intercooler, you can achieve an impressive 350 horsepower. Always remember to prioritize safety and proper tuning for the best results.
