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.

The Stage II Pumps have these additional modifications:

  • Larger gears are fitted into the oil pump which increases mid-range protection and ensures compatibility with VVT.
  • The pump is shimmed increasing maximum warm pressure from 60 PSI to 70 PSI.

All assembled billet pumps undergo the following:

  • Pump is completely taken apart, all parts undergo ultrasonic cleaning, air blast, and hand inspection.
  • Pump is hand de-burred.
  • Our industry-leading mirror finished gear set is used
  • Stainless Torx heads replace the stock fasteners
  • All fasteners are torqued to spec
  • Loctite applied to fasteners to prevent back out or loosening
  • Anaerobic sealant applied to critical areas to boost pump up speed and reduce aeration.
  • Assembly lubricant applied to all critical surfaces to get oil flowing fast on startup
  • Parts are blue-printed and issued with a specification sheet.

NOTE: Customers will be responsible for providing their own crank seal before installing. We recommend using a National brand seal, as some of the OEM seals have been too shallow to fully seal the oil drain-back port.
