Supertech SR20DE/DET Valvetrain Kit

The Supertech Valvetrain Kit is expertly designed to enhance the performance of Nissan SR20DE and SR20DET engine heads, excluding the GTi-R model. This comprehensive kit provides essential components for a reliable and efficient valvetrain upgrade tailored to your specific needs.

Key Features

• Titanium Valve Retainers: Included as the standard retainers for reduced weight and improved valve control.
• Valve Springs Options: Select from 68lb single springs or various dual spring configurations (90lb, 106lb, 116lb) to suit your performance and durability requirements.
• Valve Compatibility: Choose intake valves as standard or +1 upgrade options. Exhaust valves come in standard Inconel 7mm stem, +1 Inconel 7mm stem, or +1 Inconel 6mm stem versions to match your desired flow and strength needs.
• Valve Guides: Compatible valve guide options include none, DE head guides, or DET head guides tailored for 7mm or 6mm exhaust stems, especially recommended when changing valve sizes.
• Additional Components: Optional valve seals and chromoly valve locks are available to enhance sealing and durability.

Important Considerations: For engines equipped with hydraulic pivots, it is advised to limit valve spring pressure to no more than 90lb to maintain proper functionality and avoid premature wear.

If you plan to upgrade to larger valve sizes, specifically the 6mm stem exhaust valves, replacing the corresponding valve guides is strongly recommended to ensure proper fitment and performance.

This flexible kit allows you to customize the valvetrain setup according to your specific engine build and performance goals, making it an excellent choice for enthusiasts and professionals seeking quality and reliability.
