Custom Performance Engineering continues its MZR DISI development and pushing the limits of technology. We are proud to introduce the MagnumDI™ Stage 2 pistons.
Engineered with performance and strength in mind specifically for the Mazda MZR 2.3 DISI motor these Stage 2 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 2 Mazda Pistons have specifically designed 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. The dish design of this piston raises the compression ratio to 10.5:1, improving spool time.
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 2 pistons are the choice for reliable power.
High octane fuel is recommended.
