Are Supertech valves one-piece forgings?

Yes, Supertech performance valves are manufactured as one-piece forgings from premium alloys. This process ensures superior grain flow and mechanical strength compared to cheaper two-piece welded valves.

Do I need titanium retainers for my street car?

Titanium retainers are ideal for high-RPM racing engines because they drastically reduce valvetrain weight. For long-term street use where durability over hundreds of thousands of kilometres is the goal, Supertech also offers high-strength steel retainers which are a great compromise.

Q: How quickly can you source Supertech products?

At Chicane Australia, we specialise in the fast sourcing of Supertech Performance hardware, leveraging our established supply chain to get authentic racing internals to your door with minimal delay.

Precision-engineered valvetrain solutions for high-RPM and high-boost applications. At Chicane Australia, we provide specialised supply for Supertech Performance. By utilizing intensive F1 and Le Mans-derived testing, Supertech delivers engine internals that provide superior airflow and thermal resistance. We facilitate fast sourcing and reliable delivery across Australia for their flagship range of forged valves, dual valve springs, and titanium retainers.

The Supertech Metallurgy & Airflow Advantage

Supertech distinguishes itself through the use of exotic materials tailored to specific engine demands. Their Black Nitride intake valves feature a micro-hardness higher than the base material, providing a smoother surface finish for increased airflow and reduced friction. For extreme heat environments, their Inconel 751 exhaust valves are essential, maintaining structural integrity at temperatures exceeding 800°C—critical for high-boost Subaru EJ25 and Nissan RB26 builds. Every component, from their chrome-silicon valve springs to their FEA-optimised titanium retainers, is designed to eliminate valve float and ensure total engine synchronisation at high RPM.

Our sourcing capabilities cover the flagship Supertech Performance range:
• Forged Valves: Stainless Steel, Black Nitride, and Inconel options in standard and oversized diameters for Honda K-Series (K20/K24) and B-Series.
• Valve Spring Kits: Dual and beehive spring sets with precisely calculated rates to suit aggressive camshaft profiles on the Subaru WRX (VB/VA) and STI.
• Titanium Retainers: CNC-machined from military-grade titanium to reduce valvetrain mass and improve response on Nissan Silvia (SR20DET) and Skyline engines.
• Valve Guides & Seals: High-thermal-conductivity manganese bronze guides and Viton stem seals for superior oil control and heat transfer.

Based on the Central Coast, NSW, we provide the technical expertise to assist you in selecting the correct spring pressures and valve materials for your specific power goals. We work closely with our supply network to ensure your authentic performance internals are sourced and despatched with professional care and speed.

Supertech Performance FAQ

When should I choose Inconel over Stainless Steel valves?

Stainless steel is excellent for intake and moderate exhaust use. However, for high-boost or anti-lag equipped engines, Inconel is highly recommended for the exhaust side. Inconel is a nickel-based superalloy that remains incredibly strong at extreme temperatures where stainless steel may begin to soften or "tulip."

What are the benefits of Black Nitride coating?

Supertech's Black Nitride treatment is not just a coating; it is a hardening process that penetrates the surface of the valve. This results in a significantly harder and smoother stem, which reduces wear on the valve guides and allows for tighter tolerances and improved airflow.

How quickly can you source Supertech products?

We utilise a robust international and local supply network to provide the fastest possible turnaround. Most Supertech valve kits, springs, and retainers for popular JDM and Euro platforms are sourced and despatched within a short timeframe for delivery nationwide.
