GEN 3 3S-GTE

GSC Power-Division STD Size Intake Valve For 3SGTE

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 Single Cylindrical Valve Spring with Ti Retainer for Gen3 Toyota 3SGTE for shim under bucket includes 16 titanium retainers and 16 valve springs. This spring kit drops in with the OEM locator. These round wire springs still have the same high quality attention to detail as our popular beehive kits. The GSC5746 is Nano-peened and batched according to seat pressure within our specs. The lightweight titanium retainers are CNC machined with tolerances and repeatability that are unmatched by other brands. This keeps a consistent seat pressure across the head for ultimate reliability and performance.

• Max RPM: 8,200 RPM
• Max boost: 32 psi
• Use only Toyota OEM keeper part number: 90913-03021 for the 3SGTE. Do not swap with 2JZ keepers as height will change more than .020"/.5mm causing lower install pressure.

GSC Power-Division High Pressure Conical Valve Spring with Ti Retainer for Toyota 3SGTE for shimless/shim-over bucket includes 16 titanium retainers and 16 conical valve springs. High RPM and High Boost levels are not a problem on these kits. True conical valve springs are not a new concept and are industry proven to provide several key advantages over traditional spring designs. A major advantage of conical springs vs. traditional cylindrical or beehive springs is the damping and removal of valvetrain harmonics. Of the three designs, conical springs are the front runners in valvetrain harmonic stability. Utilizing a varying coil diameter as well as coil spacing, a conical spring acts as a natural harmonic damper in the transfer of valvetrain shock. This translates to less stress, less wear, and a longer life of the included components. This level of protection is needed in today’s engines being pushed to their physical and mechanical limits by aftermarket modifications. Every GSC conical spring offers a super finished surface treatment to go along with the patented, multi-step heat treatment process. The finished product is an extremely reliable, high-performance spring allowing the users to push higher RPMs, use more aggressive cam profiles, and turn up higher boost pressures.

• Max RPM: 10,000 RPM
• Max boost: 65 psi
