Regulators

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 Rear Oil Pressure Regulator

You could also use this in earlier year Rx7s to increase your oil pressure.

Provides 60 psi of oil pressure.

Also fits previous years for increased oil pressure.

Mazda is no longer making these, so we now manufacture them.

04-08 Rx8 Front Oil Pressure Regulator Spring 

Mazda no longer makes these so We do!

Oil Relief spring that goes in the bottom of the front cover.

Also fits 90-95 Cosmo.

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.

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.
