SZM BILLET LEFT & RIGHT VVTI TIMING CAM COVERS NISSAN GTR R35

The SZM Billet VVT-i Timing Cam Covers are high-precision replacements for the factory cast units on the VR38DETT engine. Engineered for high-horsepower builds and engines that have undergone significant machining (decking of the block or heads), these covers solve the common issue of VVT alignment failure. By providing a rigid, perfectly concentric housing for the VVT control solenoids, they ensure stable cam timing and prevent the dreaded P0011/P0021 timing over-advanced codes often seen in performance builds.

Key Technical Features

• Precision Concentricity: Unlike OEM cast covers which can suffer from core shift or misalignment after engine rebuilds, these billet units are CNC-machined to micron tolerances for perfect axial alignment with the camshaft.

• High-Grade Billet Construction: Machined from aerospace-grade aluminum to eliminate the porosity and "flex" found in factory castings, ensuring a superior seal under high thermal loads.

• Enhanced Sealing Surfaces: Features optimized O-ring grooves and gasket mating surfaces to prevent oil seepage, a common nuisance in high-vibration racing environments.

• Integrated Oil Control: Internal oil galleries are precision-drilled to maintain consistent hydraulic pressure to the VVT solenoids, ensuring lightning-fast cam phasing.
