The S55 engine, known for its performance and tuning potential, can reach new heights with the right modifications. One of the most effective upgrades is the installation of forged internals from AR Motorsport. This article explores the costs, installation process, and performance gains associated with these components.
Understanding the S55 Engine
The S55 engine is a 3.0-liter inline-six twin-turbocharged unit used in various BMW models. It is renowned for its robust performance and tuning capabilities. However, to maximize its potential, particularly for high-performance applications, upgrading to forged internals is a popular choice among enthusiasts.
Benefits of Forged Internals
Forged internals offer several advantages over stock components, making them ideal for high-performance builds. Here are some key benefits:
- Increased Strength: Forged components are stronger and more durable than cast alternatives, allowing for higher power outputs.
- Improved Reliability: They can withstand the stresses of high RPMs and boost levels, reducing the risk of engine failure.
- Weight Reduction: Many forged internals are lighter, contributing to better engine response and efficiency.
- Enhanced Performance: Upgrading to forged internals can lead to significant performance gains, especially in tuned applications.
Cost of AR Motorsport Forged Internals
The cost of upgrading to AR Motorsport forged internals can vary based on several factors, including the specific components chosen and any additional modifications required. Here’s a general breakdown:
- Pistons: Typically range from $1,200 to $2,000 depending on specifications.
- Connecting Rods: Prices can vary from $800 to $1,500.
- Crankshafts: Expect to spend between $2,000 and $3,500 for high-performance options.
- Labor Costs: Installation labor can range from $1,000 to $2,500, depending on the complexity of the job.
Installation Process
Installing forged internals requires a thorough understanding of engine mechanics. Here’s a general overview of the installation process:
- Preparation: Ensure the engine is clean and all necessary tools are available.
- Disassembly: Remove the engine from the vehicle and disassemble it to access the internals.
- Component Replacement: Replace stock pistons, rods, and crankshaft with AR Motorsport forged internals.
- Reassembly: Carefully reassemble the engine, ensuring all components are properly torqued and sealed.
- Testing: Once reassembled, the engine should be tested for performance and reliability.
Performance Gains
Upgrading to forged internals can yield substantial performance gains. Here’s what you can typically expect:
- Increased Horsepower: Many users report gains of 50-100+ horsepower with proper tuning.
- Improved Torque: Enhanced torque delivery, particularly in the mid-range, can lead to better acceleration.
- Higher RPM Capability: Forged internals allow for higher RPM limits, enabling aggressive tuning setups.
- Better Boost Handling: Increased ability to handle higher boost levels without failure.
Conclusion
Maximizing the power of the S55 engine with AR Motorsport forged internals is a worthwhile investment for serious enthusiasts. While the costs can be significant, the performance gains and reliability improvements make it a popular choice for those looking to push their vehicles to the next level.
