Evolution Motorsports has been upgrading the internals of the water-cooled Metzger engine for well over a decade, and after years of development they have released many different stages of engine upgrades. For the first time in that decade plus, the internal components of our staged engine upgrade kits are available a-la-carte. The EvoMSEvo-Spec piston sets have gone through many transformations over the years to maximize power, efficiency, and strength. Evolution Motorsports is now offering two versions on their own for you to drop into your Porsche turbo engine project; 100mm Drop-In (3.6L), or 102.6mm (3.8L) Piston Sets.
