Stage II pumps increase the overall flow by machining a deeper pocket into the oil pump and fitting larger gears in this pocket. This increases the strength of the pump, increases mid-range oil pressure, and increases the strength of the oil pump gears.
Everything the stage I pump has plus
Larger gears are fitted into the oil pump which increases mid range protection and insures compatibility with VVT.
The pump is shimmed increasing maximum warm pressure from 60 PSI to 70 PSI.
