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

GSC Power-Division Conical Valve Spring Kit with Ti Retainer for the Toyota G16E-GTS for the GR Yaris and Corolla includes 12 titanium retainers (6 Intake and 6 Exhaust) and 12 Conical valve springs and 12 new Spring Seats. 

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.
