This pump series are designed for Porsche engines. They replace the stock pump in original position and is available in 3- or 4-stage configurations. Pressure sections feature high-volume gears sized at 30–34 mm, while scavenge sizes are 30 mm and 35 mm with rotors. The 4-stage version includes 30 mm 2-lobe scavenge sections.
Both versions are designed to accommodate most stroke and connecting rod combinations. The 4-stage pump requires a block outlet O-ring boss modification and an external manifold for the return line.
