Description

Tomei has always been known for their superior engine performance parts. There is no doubt that Tomei Forged Pistons are of highest quality and craftsmanship. For high power engines that require extreme heat resistance and lightweight response, these forged pistons can endure almost anything. Definitely to be considered one of the most important parts of a rebuild. Unlike other pistons out there, Tomei pistons do not exhibit the cold piston slap issue due to the fact that they only require small clearances. Although these pistons are riced higher than other brands, what makes the Tomei pistons popular is their reputation in Japan. Being the most durable and proven over time for maintaining the best wear rate.

FEATURES:
From the combustion chamber to the cylinder, a piston works inside the core of the engine assembly where the energy of the explosion is converted into rotational movement. The piston suffers the most abuse out off all the components inside an engine, withstanding such factors as the force from constant amounts of massive energy and severe fluctuation in temperatures.

FORGED PISTONS:
Since the piston is one of the most important components in an engine assembly, transferring combusted energy to mechanical movement, it must have enough strength to withstand severe temperature fluctuations and high pressures. Stock OEM manufactured pistons are typically made from cast metal and is ideal for mass production, however they cannot sustain the stressloads when used in highly modified engines that produce over 100 horsepower per cylinder. By using forged metal made from aluminum alloy to construct Tomei pistons, the metal can then endure severe circumstances beyond the stock level. These forged pistons can withstand combustion pressures of 200 kgf and 11 tons of force with the combusted gas temperatures up to 2,500 degrees Celsius. Tomei pistons that are used in highly tuned RB26 and SR20 engines are the same type of pistons used in Group C and F1 racing.

3 DIMENSION PROFILE:
The metal expansion rate in each piston will differ according to the material of the piston and driving conditions. In order to develop the perfect piston for each and every engine types, Tomei have studied the characteristics of heat expansion in aluminum with many prototypes and countless hours on the engine bench dynamometer. The resulting product is a 3 dimensional profile of the oval and barrel design. Tomei have succeeded to produce a piston in 1/1000 mm of accuracy that applies to the appropriate piston to wall clearance.

THINNER RINGS:
Tomei selected high performance thinner piston ring for less friction loss and to prevent fluttering. This can also prevent having a floating piston ring by reducing its inertia to help cut down the blowby. In addition to it, there will be more open area for designing between the piston head and piston pin; it is possible to set the size and shape of the piston topland freely. Designed in an ideal spec the pistons strength has been dramatically increased.

TITANIUM COATED TOP RINGS (OPTIONAL EXTRA):
Tomei Racing Piston Rings help reduce increase friction durability by 30x over standard. Scuff durability is 1.4x higher than the standard rings. Tomei added the Titanium coating to the top ring for increased strength.
