Mazworx Nissan RB Torque Plate

The Mazworx Nissan RB Torque Plate is an essential tool designed specifically for Nissan RB series engines, including RB20, RB25, RB26, and RB30. This torque plate is engineered to preload the engine block, accurately simulating the cylinder head installation during the honing process.

Why Use a Torque Plate?

• Accurate Cylinder Bore Preparation: When the cylinder head is bolted to the block, the cylinder bores can slightly change shape due to the clamping force. The torque plate replicates this stress, ensuring the bore is honed to its true operating shape.
• Improved Ring Seal: By honing the cylinders with the torque plate installed, you achieve a better seal with piston rings, which enhances engine efficiency and performance.
• Essential for Sleeved Blocks: For engines with cylinder sleeves installed, using a torque plate during honing is crucial to maintain precise cylinder diameter and geometry under operating conditions.

Constructed to match the exact specifications of Nissan RB engines, the Mazworx torque plate is a valuable investment for engine builders and enthusiasts aiming for optimal cylinder bore accuracy and engine longevity.
