Boundary VQ-BBP-DE Billet Back Plate for Nissan VQ 3.5L DE

The Boundary VQ-BBP-DE is a high-performance billet steel back plate designed specifically for Nissan VQ 3.5L DE oil pumps. This precision-engineered component is manufactured from billet steel rather than traditional cast aluminum, delivering exceptional rigidity and durability for demanding performance applications.

Key Features:

• CNC-machined from billet steel for superior strength and rigidity compared to aluminum alternatives
• Advanced CFD simulation and 3D precision milling for optimized oil flow characteristics
• Deeper porting and 5th axis finished ramps to reduce cavitation and aeration
• Surface-ground finish creates an optimal seal to minimize oil bypass
• Reduces air ingestion and blow-by for more consistent oil pressure throughout the RPM range
• Increases oil volume delivery while reducing foam formation for better engine bearing protection

Boundary's billet back plates are engineered to deliver less leak-by, less aeration, less cavitation, and more high RPM oil flow than stock components. Manufactured in-house at Boundary's Dallas, Texas facility using state-of-the-art CNC equipment, each back plate undergoes rigorous quality control to ensure consistent performance. This upgrade component is ideal for naturally aspirated and forced induction VQ35DE applications where superior lubrication is critical for engine longevity and performance.
