Mazworx Pro Street Billet VQ35DE Block

The Mazworx Pro Street Billet VQ35DE Block is engineered as a direct replacement for the factory VQ35DE block, developed from extensive racing experience and rigorous performance testing. Crafted from high-quality 6061-T6 aluminum and fully machined in-house, this billet block is designed to meet the demands of high horsepower street builds and Pro Street drag racing applications.

Key Features

• Enhanced Strength: The block features main caps fabricated from durable 4140 chromoly steel, secured with 4 9″ studs per cap, and reinforced by a billet 6061-T6 girdle plate to provide superior rigidity under extreme loads.
• Flexible Crank Compatibility: Engineered clearance accommodates stroker cranks when used with steel rods, offering builders versatility for various performance setups.
• Optimized Cylinder Sleeves: By eliminating oil squirters, there are no notches required in the sleeves, allowing pistons to be used without additional clearance modifications.
• Two Versions Available:
  • Wet Version: Equipped with Darton MID sleeves for applications requiring liquid cooling.
  • Dry Version: Designed for Pro Street drag racing where methanol fuel is utilized; this version features no cooling jackets and dry sleeves for increased block strength.
• Improved Cylinder Head Clamping: Both block versions are machined to accommodate 9″ head studs, enhancing cylinder head retention and reliability at high power levels.

This billet block represents a significant upgrade over the OEM VQ35DE block, providing a robust foundation for high-performance Nissan VQ35 engine builds where strength and durability are critical.
