What is the main benefit of using titanium retainers?

Titanium retainers are significantly lighter than traditional steel retainers. This reduction in mass helps improve valvetrain stability, especially at higher engine speeds, and can allow the engine to rev more freely.

Do I need to use specific camshafts with this kit?

While this kit is designed for performance applications, it's recommended to use it with camshafts that complement its capabilities. Careful attention to valve-to-piston clearance is crucial, particularly with aftermarket camshafts.

What does the 'P-D' in the product name stand for?

P-D stands for Power Division, which is the performance-oriented line from GSC, indicating these parts are intended for enhanced engine builds and higher performance applications.

Product Details

This is the GSC Power Division P-D Valve Spring and Titanium Retainer Kit, specifically designed for Subaru EJ Turbo DOHC engines found in models like the 1999-2014 Impreza. If you're looking to upgrade your engine's valvetrain for higher RPMs or more aggressive camshafts, this kit is a solid choice. It helps ensure your valves close reliably at higher engine speeds, preventing valve float and maintaining engine integrity under stress.

The kit includes well-built valve springs and lightweight titanium retainers. Titanium retainers are notably lighter than steel, which reduces the overall mass the valvetrain has to move. This mass reduction can lead to improved valvetrain stability and allow the engine to rev more freely. GSC Power Division is known for making robust components, and this kit is built to handle the demands of a performance-oriented EJ engine.

When installing this kit, remember that it's designed to work with specific camshaft profiles and requires careful attention to valve-to-piston clearance, especially if you're using aftermarket cams. It's a component that pairs well with other engine modifications aimed at boosting performance.
