ScienceofSpeed Forged Pistons

ScienceofSpeed offers custom designed forged aluminum pistons for the NSX. Custom compression and bore sizing for both naturally aspirated and forced induction applications are available. These pistons are the most advanced available featuring a lightweight low friction design with proprietary dome designs that have been mapped from 3.0L and 3.2L cylinder heads for maximum compression and quench performance.

Each piston is custom designed and tailored for it's specific application. Pistons are manufactured from high quality forgings and CNC machined to exacting standards. We feature OEM-type replacement pistons as well as high performance pistons for natural aspiration and forced induction (supercharged, turbocharged) applications. Natural aspiration pistons feature lightweight high performance designs while forced induction pistons feature durable designs designed for high horsepower.

These pistons are compatible with the factory 3.0L engine block as well as 3.0L and 3.2L engine blocks that have been sleeved. Pistons are supplied complete with ring, pin, and lock sets.

Special race coating bonds piston skirts with moly (Molybdenum Disulfate) based coating. Coating results in reduced piston friction through improved lubrication and increased ring life through thermal insulation.

We offer 5 general categories of pistons depending on application (naturally aspirated or forced induction), diameter range, and stroke). High performance NA pistons feature additional internal CNC milling for weight reduction. Please contact us for specific custom piston requirements.
