Upgrading to ARP head studs on the SW20 Turbo is an essential modification for those looking to push their vehicle’s performance beyond 350 horsepower. This upgrade not only enhances the reliability of the engine but also helps in maintaining optimal performance under high-stress conditions. In this article, we will explore the benefits of ARP head studs, the installation process, and some tips for ensuring a successful upgrade.
Why Choose ARP Head Studs?
ARP (Automotive Racing Products) is renowned for its high-quality fasteners, and their head studs are no exception. Here are some reasons why upgrading to ARP head studs is a wise choice:
- Increased Strength: ARP head studs are made from high-quality materials that provide superior tensile strength compared to factory bolts.
- Improved Clamping Force: These studs maintain a consistent clamping force, which is crucial for preventing head gasket failure.
- Enhanced Durability: ARP head studs are designed to withstand the rigors of high-performance applications, making them ideal for turbocharged engines.
- Easy Installation: The design of ARP head studs allows for easier installation compared to traditional bolts.
Preparing for the Upgrade
Before diving into the installation process, it is essential to prepare adequately. Here are some steps to ensure you’re ready:
- Gather Necessary Tools: Make sure you have all the required tools, including a torque wrench, socket set, and a head gasket set.
- Inspect Engine Components: Check the condition of the engine components, including the cylinder head and block, for any signs of damage.
- Clean the Work Area: A clean workspace will help prevent debris from contaminating the engine during the upgrade.
Installation Process
Installing ARP head studs involves several steps. Follow this guide to ensure a successful installation:
- Remove the Cylinder Head: Begin by draining the coolant and removing any components obstructing access to the cylinder head. Carefully unbolt and lift the cylinder head off the engine block.
- Clean the Surfaces: Thoroughly clean the mating surfaces of the cylinder head and engine block to ensure a proper seal with the new head gasket.
- Install New Head Gasket: Place the new head gasket onto the engine block, ensuring it is aligned correctly.
- Insert ARP Head Studs: Insert the ARP head studs into the block, ensuring they are seated properly. Apply ARP assembly lubricant to the threads for accurate torque readings.
- Reinstall the Cylinder Head: Carefully place the cylinder head onto the new gasket and align it with the head studs.
- Torque the Head Studs: Follow the manufacturer’s recommended torque sequence and specifications to tighten the head studs. It is crucial to follow the proper torque sequence to avoid warping the cylinder head.
Post-Installation Tips
After installing the ARP head studs, there are a few additional steps and considerations to keep in mind:
- Check for Leaks: After reassembling the engine, check for any coolant or oil leaks before starting the engine.
- Break-In Period: Allow the engine to go through a break-in period, following the manufacturer’s guidelines for optimal performance.
- Monitor Performance: Keep an eye on engine performance and temperatures, especially during the first few drives after the upgrade.
Conclusion
Upgrading to ARP head studs on your SW20 Turbo is a critical step for those looking to achieve reliability at 350+ horsepower. By following the proper installation procedures and taking the necessary precautions, you can ensure that your engine performs optimally under high-stress conditions. This upgrade not only enhances your vehicle’s performance but also provides peace of mind knowing that your engine is built to handle the power.
