Supertech High Performance Block Guard for 2ZZ-GE Engine 

Supertech Block Guards are engineered to provide critical reinforcement to open-deck engine blocks in high-stress applications. Whether you're building for boost, high RPM, or race-level abuse, these CNC-machined inserts improve cylinder stability and reduce the risk of sleeve distortion and cracking.

Each Block Guard is manufactured from high-strength aluminum alloy and designed for an exact fit. The guard helps distribute pressure evenly across the cylinder wall and maintains block integrity under extreme loads. Designed for a Toyota 2ZZ-GE application, it allows improved coolant flow while increasing structural rigidity where it's needed most.

Features:

• CNC-machined aluminum construction for precision fit and strength
• Supports open-deck engines by reinforcing the upper sleeve area
• Engineered for a Toyota 2ZZ-GE block configuration
• Maintains coolant passages for efficient heat dissipation
• Perfect for high-boost, high-RPM, or track builds

Benefits:

• Increased reliability and reduced risk of cylinder distortion
• Improved block rigidity under high-pressure conditions
• Enhanced cooling performance compared to full closed-deck conversions
• Essential upgrade for competitive and high-output builds

Fensport Tip: Ideal for turbocharged, supercharged, or high-compression naturally aspirated builds, this is a must-have upgrade for anyone pushing the limits of factory block design.
