Engineered with performance and strength in mind specifically for the Mazda MZR 2.3 DISI motor these Stage 3 pistons will hold up to almost anything. Made using a state-of-the-art forging process with extensive heat treating and special finishing, cp-e ensures optimum reliability which is exactly what is needed in a high performance engine.


Precision CNC machined to cp-e spec, Stage 3 pistons have even more defined valve pockets and a dome with unique features to optimize fuel distribution within the cylinder. The extra pocket in the dome design sends fuel up towards the spark plug, optimizing the mix with oxygen and in turn making the burn process more efficient.


This piston has been designed specifically to support a wider pulse width to enable greater hp and extra fuel. Compression has been raised to 10.5:1 in the Stage3 version of the MagnumDIpistons. This higher compression will give you the same power at lower boost levels. It is only available in an overbore, 90mm, for use with a 2.4L motor . This option is for the driver looking to race their car, but it is also completely streetable.


The forging, pin, rings, and design features have all proven themselves to well over 1000hpfor the ultimate in reliability and street-ability.


The pistons are machined with a special cam and barrel design helping with piston positioning within the cylinder and its movement with stress and heat, also reducing the noise, commonly acquired with forged internals. They are also coated for reduced friction and noise and to promote oil lubrication.


cp-e knows the DISI MZR 2.3 inside and out, and has done extensive research and engineering to bring you the proper tools for a successful, high horsepower solution. The MagnumDI Stage 3 pistons are the choice for reliable power.
