The Heart of The Issue

The oil pump is literally the heart of the engine. Without an adequate supply of oil your engine will destroy itself. EJ series Subaru engines are notorious for failures related to low oil pressure. Don't let your engine fall victim to a bearing failure or rod knock.

FAQ

Why do I need an upgraded oil pump?

Increasing your oil pressure and volume ensures that your engine always has an adequate supply of oil exactly where you need it. Porting on the inlet side of the pump also helps to avoid cavitation

Which IAG Oil Pump Should I Choose For My Build?

The IAG Stage 1 Blueprinted Oil Pump is intended for stock engines or built engines up to an IAG Stage 1 Short Block w/ Single or Dual AVCS

The IAG Stage 2 CNC Ported Oil Pump is intended for modified engines up to an IAG Stage X Short Block w/ Single or Dual AVCS

Why didn't IAG modify a 12mm Pump?

During testing we found that our Stage 2 11mm pump outperformed even a ported 12mm JDM pump. The JDM 12mm oil pumps are not readily available in the US and come at a substantially higher cost. These factors make the modified 12mm pump not the best choice at this time. However, our engineers are continuing to further develop and test 12mm pumps to determine if any significant improvements are possible.
