These upgrades deliver superior strength, improved mid-range oil pressure, and increased gear durability.

Key Features of the Stage II Oil Pump:

• Enhanced Gear Design: Fitted with larger, stronger gears for improved mid-range oil pressure and optimal compatibility with Variable Valve Timing (VVT) systems.
• Increased Maximum Pressure: Shimmed to raise the maximum warm oil pressure from 60 PSI to 70 PSI, ensuring greater protection under demanding conditions.
• Everything in Stage I, Plus More: Retains all the benefits of the Stage I pump while delivering advanced features for high-performance applications.
