GSC Power-Division Conical Valve Spring with Ti Retainer for RB26DETT includes 24 titanium retainers, 24 conical valve springs, and 24 chromoly valve spring seats. 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. GSC Power Division Conical Spring RB26DETT

GSC Power-Division Beehive Valve Spring Kit with Ti Retainers for the Nissan VQ35DE includes 24 titanium retainers, 24 beehive valve springs, and 24 valve spring shims. Our beehive spring is made with an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilities. These springs have the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control.

• Max RPM: 8,500 RPM
• Max boost: 30 psi
• Up to 12.1mm lift cam

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 Short Intake Valve 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
• Valve tip lengths - we have taken extra time to adjust tip heights on this application 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. The GSC2056-01, GSC2056-12 valve protrusion has been shortened by .15mm to reduce the need to tip the valves on cylinder heads that are receiving a valve job. For directl factory replacement, where a valve job is not being performed, please use part number GSC2050-01 or 2050-12

GSC Power-Division Super Alloy Exhaust Valves for Nissan VR38DETT are for those running high horsepower, high EGT set ups that need a valve that will last in 2000°F conditions. The Super Alloy Exhaust valves have chrome polished stems to create a smooth, durable finish for added life and better lubricity, especially when paired with the GSC Manganese bronze valve guides. Strength, heat resistance, and performance are engineered into every valve. Under head dish is maximized for weight savings while swirl polished and back cut heads promote better air flow without sacrificing durability.

GSC Power-Division Conical Valve Spring Kit with Titanium Retainer for the Nissan VR38DET comes complete with 24 titanium retainers, 24 conical valve springs, and 24 valve spring shims. Conical valve springs, although not a new concept, have proven themselves in the industry, offering several key advantages over traditional spring designs.

One of the primary benefits of conical springs compared to cylindrical or beehive springs is their superior ability to dampen and eliminate valvetrain harmonics. Among these designs, conical springs stand out as frontrunners in ensuring valvetrain harmonic stability. By incorporating varying coil diameters and spacing, conical springs naturally act as harmonic dampers, effectively reducing valvetrain shock. This results in decreased stress, minimized wear, and prolonged lifespan of the included components, a crucial level of protection for modern engines pushed to their physical and mechanical limits by aftermarket modifications.

Each GSC conical spring undergoes a meticulous process, featuring a super-finished surface treatment in addition to our patented, multi-step heat treatment. The result is an exceptionally reliable, high-performance spring that enables users to push higher RPMs, utilize more aggressive cam profiles, and increase boost pressures with confidence.

• Max RPM:  10,000 RPM
• Max boost: 40 psi
• 1,500 HP

GSC Power-Division is glad to reveal the newest addition to our camshaft line, the GSC7045 forged billet S3 set for the VR38 powered GT-R. This isn’t just another cam - lots of research and development went into every aspect of these bump sticks. The billet cores for these cams are proprietary and made in house at GSC. We developed stronger, lighter cams with additional fatigue and wear resistance. CNC machining and grinding gives us the most accurate and repeatable camshafts possible, with precision gun drilling down the center of the cam for oil delivery and weight reduction. This far exceeds OEM durability with the performance GSC Power-Division is world famous for. For 1500 + WHP builds only. GSC Power Division S3 camshaft VR38DETT

Required for the 7045S3 are the GSC5068 Beehive valve springs and lightweight titanium retainers, this combination will keep the valve train happy up to 9800 RPM at 60psi of boost.
