The cylinder head and block are manufactured from aluminium alloy to maximise weight reduction. Stiffer valve springs, Forged Steel Crankshaft and Forged Steel Con-rods with fully floating gudgen pins are used to ensure that the engine is capable of coping with high revs. Pocketed pistons with coated side skirts have been included to maximize horsepower, minimize friction, and provide Improved wear resistance. Because of the up-rated components, ongoing performance optimisation with-out further work required to the bottom end is easily achievable.

 

In an effort to reduce the engine noise and vibration Mazda have used a “silent type” timing chain, torsion damper crankshaft pulley, and a cylinder block that incorporates integrated main bearing caps together with a ladder frame structure.
