4Piston Ported B-series Oil Pump - B-series

4Piston Ported B-series Oil Pump - B-series

The stock oil pump is a great piece for up to 9,000 rpm in drag racing and 8,000 rpm in endurance racing. Past that, there can be cavitation issues and oil pressure drops as temperatures rise. 4Piston's ported B-series pump increases flow by 25% and will allow continuous use above 9,000 rpm.

The pump has been tested as high as 12,000 rpm with great success. 4P starts with a brand new OEM oil pump from Honda, disassemble, port and smooth oil passages to increase flow. The pumps are then cleaned, oiled, reassembled and repackaged.

This part is cheap insurance to protect your multi-thousand dollar investment!

Engine applications: All B-series engines
