Toda High Compression Forged Piston Kit (NA8C | NB8C – 85mm | 1928cc) Mazda Miata (B6 | BP)

The basic form of the piston is an elliptical barrel. This forms the basis from which each part is subjected to high loads and measured for thermal expansion to accuracy of 1/1000(mm). The top edge of the piston uses a castellation design to reduce sticking, improve lubrication and sealing. The design also acts as a scuff-band to reduce run in time. TODA

THE KNOWLEDGE

Pistons

What are they?

Pistons are cylinder shaped metal inserts with one closed end which bears the brunt of the combustion force in the chamber - at the opposite open end a piston pin attaches to a connecting rod, which in turn powers the crankshaft. Each piston is fitted with three malleable piston rings that create an air tight seal once inside the engine cylinder.

What are they made from?

Pistons tend to be made from cast iron, steel or aluminium alloy. Replacement pistons can provide many advantages over stock pistons; they can be made from stronger and/or denser material, they can be specially prepared (forged, heat treated) for higher durability and tolerances, piston surfaces vary between manufacturers too.

Forging and Billet

For those with a healthy budget and the desire to build an engine capable of enduring high load, constant load, or both (think Le Mans 24) forging and/or billet are both baller upgrade options. The increased density of forged steel allows a higher engine compression to build; increasing power output and available RPM range. When taking things to the next level, head work to create a wider piston cylinder bore to increase displacement capacity, or stroker-kits which extend the con rod for a deeper stroke, again increasing displacement.
