Oil Pressure Regulator

The Racing Beat-manufactured Street High Performance Rear Oil Pressure Regulator for the RX-8 interchanges exactly with the stock rear oil pressure regulator on all 2004-2008 Renesis engines. It is designed to bypass at 90-95 PSI, making it well suited for street-ported Renesis engines and a piece of mind upgrade for normal rebuilds. As supplied by Mazda, the factory pressure regulator is intended to bypass at maximum nominal rate of 80 PSI

Thermal bypass pellet

The thermal bypass pellet is designed to replace the stock thermal pellet found in the front of all eccentric shafts from 1986 onward the stock pellet works like a thermostat restricting oil flow to parts of the engine when cold. however when they fail they generally fail in the closed position leading to permanently reduced oil flow this is not good for your engine. The Racing Beat bypass pellet removes this point of possible failure. The pellet replaces the stock unit and allows full oil flow from cold. So by using the Eccentric Shaft Thermal Bypass Pellet Replacement you will know the oil is reaching the parts it should at all times.
