GSC Power Division Intake Valve GTE

When creating our new valve line we set out to create the best performance, longest lasting valves available to the aftermarket. Using advanced 3D design and simulation software, we have created a stronger and higher flowing valve head design. We flow test prototype valve heads in the specific applications to make sure we have the highest flowing valve head available on the market today. With the materials used, we have less valve distortion at the face than any of the tested designs. Less distortion allows for better sealing under extreme conditions and more consistent performance throughout the life of the valve. GSC Power-Division's new valves are sure to become the industry standard for sport compact performance valves.

Valve Features

• Swirl polished heads for smoother air flow over the valve

• Back cut to reduce valve weight for higher RPM, higher boost pressure, and allow for more aggressive cam profiles without increasing valve spring seat pressures

• Valve stems are micro polished to allow for less oil retention on the stem, which creates less drag on the stem to guide for a smoother motion

• Intake valves are a modified 21-4n stainless and exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity

• Valve tips are either hardened or have a stelite wafer tip fused so that the tip is within 5 Rockwell C of the rocker or valve tappet for extended life and less wear

• Valve tip lengths - we have taken extra time to adjust tip heights on the applications to require less tipping of the valve, to maintain proper tip height for proper valve train geometry, and to cut down on install times when setting valve lash

• We have also adjusted the keeper groove to properly balance intake and exhaust spring pressures to reduce the use of valve spring shims and maximize performance from our spring and retainer kits

• Valves will work with an OEM keeper/lock or, when available, our upgraded keeper/lock. It is not mandatory, but it is suggested, that any valve lock not be reused on performance applications due to material grooving

Upgrade your Toyota G16E-GTS Engine with GSC Power Division Super Alloy Performance Exhaust Valves, built for superior airflow, efficiency, and durability in turbocharged engines.

The back cut design improves airflow, increasing power output and RPM potential. Micro-polished valve stems reduce friction and oil retention, ensuring smoother operation and longer component life, even at high RPMs.

Crafted from super alloy materials, these valves withstand the extreme heat and stress of turbo and supercharged engines. Hardened valve tips ensure extended durability and optimal contact with the rocker or valve tappet.

Designed for OEM replacement, these valves fit seamlessly with OEM keeper/lock systems. GSC Power Division recommends using new valve locks in performance setups to avoid material grooving.

Valve Features:

• Enhanced Engine Efficiency: Improved airflow leads to better engine breathing, resulting in greater power output and overall engine efficiency in both turbocharged setups.
• Back Cut Design: Strategically crafted to optimize air flow, allowing your engine to achieve higher RPMs and improved performance across the powerband.
• Micro-Polished Valve Stems: Minimizes oil retention on the valve stem, significantly reducing friction and drag, ensuring smoother motion within the valve guide for improved efficiency and longevity.
• Super Alloy Construction: Designed to withstand extreme temperatures, especially in turbocharged and supercharged engines, ensuring consistent performance and durability under high-stress conditions.
• Hardened Valve Tips: The valve tips are reinforced using a mid-stem friction weld process to extend valve life and minimize wear, ensuring optimal contact with the rocker or valve tappet.
• OEM Keeper/Lock Compatibility: Designed to work seamlessly with OEM triple groove keeper/lock systems. While compatible, we recommend not reusing old valve locks in performance applications to avoid the risk of material grooving.
• GSC Power Division Quality: Backed by GSC Power Division's commitment to delivering top-tier quality and performance, ensuring that every valve meets the highest standards in the industry.

True conical valve springs aren’t a new concept—they’ve been proven in the industry to offer several key advantages over traditional spring designs. One of the biggest benefits of conical springs compared to traditional cylindrical or beehive springs is their ability to dampen and eliminate valvetrain harmonics. Out of the three designs, conical springs lead the way in maintaining valvetrain harmonic stability.

Thanks to their varying coil diameter and spacing, conical springs act as natural harmonic dampers, absorbing the shock in the valvetrain. This means less stress, less wear, and a longer life for your engine components. This level of protection is essential for today’s engines, which are being pushed to their physical and mechanical limits.

Every GSC conical spring undergoes a super-finished surface treatment in addition to a patented, multi-step heat treatment process. The result? A super reliable, high-performance spring that lets you push higher RPMs and use more aggressive cam profiles with confidence.

If you’re looking to get the most out of your engine, GSC conical springs are the way to go. They’re built to perform, engineered to last, and designed to let you take your engine to the next level.
