GSC SWAG
GSC Power-Division valve guides are made from a proprietary blend of Manganese Bronze and turned on dedicated precision CNC turning centers. With performance and aftermarket installation in mind, we hold extremely tight tolerances on through-hole concentricity to outside diameter which minimizes the required honing time for the installer. True-to-size outside diameters minimize honing of guide bosses on cylinder heads that don't require boss service. Our guides are easier to install and shaped to improve air flow instead of just copying OEM design.

GSC Power-Division HIGH PRESSURE Conical Valve Spring kit for the Nissan VR30DDTT
GSC5084
Regular price £888.00 Sale price £818.29 Save £69.71GSC Power-Division High Pressure Conical Valve Spring Kit with Ti Retainer for the Nissan VR30DDT includes 24 titanium retainers, 24 conical valve springs, and 24 valve spring seats.
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 valve spring allowing the users to push higher RPMs, use more aggressive cam profiles, and turn up higher boost pressures.

GSC Power-Division Billet S1 camshaft set for Nissan VR30DDTT 400Z/Q50/Q60
GSC7043S1
Regular price £1,520.00 Sale price £1,400.68 Save £119.32GSC Power-Division is glad to reveal the newest addition to our camshaft line, the GSC7043 forged billet S1 set for the VR30 powered Infiniti/Nissan. 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.
Required for the 7043S1 cams are the GSC5083 Conical valve springs and lightweight titanium retainers. These will keep the valve train happy up to 9000 RPM at 40psi of boost. GSC specifically designed the valve springs and retainers for the high horsepower VR30DDTT.

When creating our valves 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. 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.
Valve Features:
-
Enhanced Engine Efficiency: Improved airflow leads to better engine breathing, resulting in greater power output and efficiency.
- Back Cut Design: Strategically improves air flow, enabling higher RPMs,
- Micro-Polished Valve Stems: Minimizes oil retention on the stem, reducing drag for a smoother motion within the guide.
- Premium Material: Exhaust valves are crafted from modified 23-8n stainless steel for exceptional strength and performance.
- Valve Tips: Hardened or fused with a stellite wafer tip, ensuring extended life and minimal wear, maintaining proximity to the rocker or valve tappet.
- Compatibility: Our valves seamlessly work with OEM keeper/lock systems. While not mandatory, we advise against reusing any valve locks on performance applications due to potential material grooving.
- Quality: Backed by GSC Power-Division's commitment to quality and performance.
