Regulators
Mazda Oil Pressure Regulators
Sort by:Recommended
69-11 Rx7 & Rx8 Atkins Competition Adjustable Rear Oil Pressure Regulator (4352-14-250)
Replaces the stock secondary (rear)regulator. With the use of a high capacity oil pump, the competition regulator allows oil pressure in the system to reach 105-115 psi.
It is also recommended to shim the front pressure regulator 1/8" to ensure it does not limit system pressure.See below for shimming details.
93-95 Rx7 Rear Oil Pressure Regulator (N3A1-14-230)
93-95 Rear Oil Pressure Regulator
You could also use this in earlier year Rx7s to increase your oil pressure.
93-95 Rx7 Front Oil Pressure Regulator Spring (N3A1-14-273A)
Also fits previous years for increased oil pressure.
Mazda is no longer making these, so we now manufacture them.
72-08 Rx7 & Rx8 Front Oil Pressure Regulator Piston (0839-14-115)
Fits all rotary engines.
Fits:
- Rx3
- Rx7
- 04-08 Rx8
- 90-95 Cosmo
Goes inside the front cover.
04-08 Rx8 Front Oil Pressure Regulator Spring (N3H1-14-237)
The Spring in the front cover.
These are no longer available, but we have some left.
79-08 Rx7 & Rx8 Front Cover Oil Regulator Spring Plug Screw (0839-14-274)
Holds the front oil pressure regulator, and screws into the bottom of the front cover.
Also fits 90-95 Cosmo.
74-91 Front Oil Pressure Regulator Spring (0839-14-273A)
Oil Relief spring that goes in the bottom of the front cover.
Also fits 90-95 Cosmo.
74-91 Rx7 Increased Oil Pressure Kit (ARE401)
Increase the oil pressure in your 74-91 Mazda Rx7 with this kit.
You will increase from 60psi to 110psi in 79-91 Rx7.
Rear Competition Oil Pressure Regulator
FD Front Oil Pressure Regulator Spring
Regulator Shims
Remove your oil pan and install the competition rear oil pressure regulator in your rear cast iron, then remove your stock regulator spring from the bottom of the front cover and replace it with this FD spring and put the two shims under it and screw the cap back into place, replace your oil pan and you will have more oil pressure.
A new turbo oil pump and an upgraded AN oil line kit would be a great addition to this kit.Front Oil Pressure Regulator Spring Shim (AN960-10)
Fits all rotary engines.
Two of these are needed to shim the front regulator spring to the suggested 1/8". These are a nice addition to any engine where higher oil pressure would benefit you.
We put two of these in every engine under the front oil pressure regulator spring in the front cover.
