Mazda RX-7 13B Oil Pump Cavity CNC Machining

Opening up the Oil Passage on your rotary motor is a must for high performance motor.
This service removes the inconsistent casting left behind from the factory and is instead finished with a smoothed consistent surface. In addition, we add a grooves for an O-Ring to best seal the oil pump to housing.
The original cavity along with the new machined surface have been flow tested using SOLIDWORKS simulation resulting in 23% more flow over stock.
