Boundary C30A-OPG-M Billet Oil Pump Gearset for Honda C30A 3.0L V6 NSX with MartenWear Treatment

The Boundary C30A-OPG-M is a premium billet oil pump gearset engineered specifically for the Honda C30A 3.0L DOHC VTEC V6 engine found in the iconic Acura NSX. This high-performance upgrade replaces the factory powdered metal oil pump gears with precision-machined chromoly billet gears designed to handle the extreme demands of high-RPM sports car applications.

Advanced Manufacturing Process:

Boundary manufactures these oil pump gears 100% in-house at their Dallas, Texas facility using premium 4140 chromoly billet steel. Each gearset undergoes a rigorous heat treatment process including quenching from extreme temperatures and tempering to create an indestructible core. After precision CNC machining, Boundary applies their proprietary ColdFlow surface hardening process, followed by MartenWear dual-stage heat treatment for enhanced wear resistance and reduced friction. The process is completed with a mirror-polished finish for optimal performance.

Key Features:

• CNC machined from 4140 chromoly billet steel for superior strength
• MartenWear dual-stage heat treatment for operation over 9,000 RPM
• Proprietary ColdFlow surface hardening process
• Mirror finish for reduced friction and higher efficiency
• Precision blueprinted and matched gearset
• 110,000 PSI yield strength versus less than 6,000 PSI for OEM powdered metal gears
• Proven in applications exceeding 400 horsepower per liter
• Made in USA with lifetime warranty

Application:

Designed as a direct replacement for Honda C30A 3.0L V6 engines found in 1991-1996 Acura NSX models. Essential upgrade for forced induction builds, high-RPM naturally aspirated applications, or replacing worn factory gears. The MartenWear treatment makes this gearset ideal for extreme racing conditions and sustained high-RPM operation.

Each Boundary oil pump gearset is manufactured to exacting tolerances and shipped with blueprinting documentation. Installation requires no modifications to the stock oil pump housing, making this a straightforward upgrade for NSX owners seeking ultimate oil system reliability.
