Ported and shimmed Honda/Acura B-series P72 / OBD2 / CKF-style oil pump.
This listing is for the OBD2-style pump with the crank sensor provision / CKF boss on the front of the pump. This is the style commonly associated with OEM part number 15100-P72-A01 and commonly used on many OBD2 B-series setups.
Each pump is disassembled, cleaned, internally ported and blended, relief spring shimmed, washed/blown out after modification, inspected, lubricated, and reassembled before shipping. This is a finished modified oil pump product, not an untouched Honda service-replacement pump.
Commonly used on B16, B18, and B20 Honda/Acura B-series builds depending on block, ECU, crank sensor setup, and lower timing cover.
What was done:- OEM Honda/Acura P72-style oil pump core- Fully disassembled- Exterior cleaned- Internal oil passages ported and blended- Relief spring shimmed- Relief valve and rotor cavity inspected- Fully washed and blown out after modification- Lubricated, reassembled, and ready for installation
Important fitment note:This is the crank-sensor-boss style pump, commonly called the P72 / OBD2 / CKF oil pump. It is different from the older OBD0/OBD1 PR3/PR4-style pump that does not have the crank sensor provision.
Not sure which style you need?Look at the front of your old oil pump. If it has the crank sensor mounting area/boss, this is the correct OBD2/P72/CKF-style pump. If your old pump has no crank sensor area, you need the OBD0/OBD1 PR3/PR4-style pump instead.
Not included unless pictured:- Crank/CKF sensor- Lower timing cover- Pickup tube- Crank seal- Pump O-ring- Mounting hardware- Reluctor/trigger parts
Buyer is responsible for verifying fitment before purchase. This pump fits many B-series setups, but exact compatibility depends on the engine, timing cover, ECU, crank sensor setup, and swap configuration.
This is not marketed as a high-volume pump. Porting and shimming do not change pump gear displacement. It is a modified OEM-style pump with ported passages and a shimmed relief spring.
