Stock vs. Katech CNC-Ported Oil Pump

A stock production oil pump is built for broad OEM use. The Katech CNC-Ported Wet Sump Oil Pump starts with a new GM LS6 pump, then receives CNC inlet porting, blueprinting, and inspection procedures intended to improve flow path efficiency and provide greater consistency from pump to pump. For performance LS builds, that added preparation can be an important advantage where oil control matters.

Engineering Process

• Starts with a brand new GM LS6 G-rotor oil pump
• CNC-porting at the oil inlet to improve the entry path into the pump
• Blueprinting and inspection procedures to verify internal consistency

Why Choose Katech Engineering

Katech Engineering applies strict machining and inspection standards developed through decades of LS engine development. Each oil pump is CNC-ported and blueprinted to deliver consistent oil flow and pressure stability in high-performance applications.
