Installing Forged Internals in Your Wrx Built Engine: Strengthening for 500+ Hp

When it comes to maximizing the performance of your WRX engine, upgrading to forged internals is a crucial step, especially if you’re aiming for over 500 horsepower. This article will guide you through the process of installing forged internals in your WRX built engine, ensuring that it can handle the increased power and stress.

Understanding Forged Internals

Forged internals, such as pistons and connecting rods, are designed to withstand higher levels of stress and heat compared to their cast counterparts. This makes them ideal for high-performance applications. Here are some key benefits:

  • Increased Strength: Forged components are denser and stronger, reducing the risk of failure under high loads.
  • Better Heat Resistance: They can handle higher temperatures, essential for turbocharged engines.
  • Improved Performance: Lighter components can enhance engine response and efficiency.

Preparing for Installation

Before diving into the installation process, it’s important to gather all necessary tools and materials. Here’s a checklist to help you prepare:

  • Forged pistons and connecting rods
  • Engine hoist
  • Torque wrench
  • Socket set
  • Engine assembly lubricant
  • Gasket set

Step-by-Step Installation Process

Step 1: Remove the Engine

Start by safely removing the engine from your WRX. Ensure all connections, including electrical and fuel lines, are disconnected. Use an engine hoist to lift the engine out of the bay.

Step 2: Disassemble the Engine

Once the engine is out, disassemble it carefully. Remove the cylinder head, oil pan, and other components to access the internals. Keep track of all bolts and parts to avoid confusion during reassembly.

Step 3: Remove Old Internals

With the engine disassembled, remove the old pistons and connecting rods. Take your time to ensure that no debris is left in the engine block, as this can cause issues later on.

Step 4: Install Forged Pistons

Begin the installation of your forged pistons. Apply engine assembly lubricant to the piston rings and carefully insert them into the cylinder bores. Make sure to follow the manufacturer’s specifications for ring gaps and orientation.

Step 5: Install Forged Connecting Rods

Next, install the forged connecting rods. Align them properly with the crankshaft and torque them to the specified settings. This step is crucial for ensuring the longevity of your engine under high performance.

Step 6: Reassemble the Engine

Once the forged internals are installed, carefully reassemble the engine. Replace all gaskets and seals to prevent leaks. Ensure everything is torqued to the manufacturer’s specifications.

Step 7: Reinstall the Engine

With the engine fully assembled, it’s time to reinstall it back into the WRX. Again, use an engine hoist for safety and ensure all connections are securely fastened.

Post-Installation Checks

After installation, it’s vital to perform a series of checks to ensure everything is functioning correctly:

  • Check for oil leaks around gaskets and seals.
  • Ensure all electrical connections are secure.
  • Inspect fluid levels and top off as necessary.

Conclusion

Installing forged internals in your WRX built engine is a significant upgrade that can unlock the potential for 500+ horsepower. By following the steps outlined in this guide, you can ensure a successful installation that enhances your vehicle’s performance and reliability. Always remember to consult with professionals if you are unsure about any part of the process.
