Tomei have 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. The newly added valve recess provides necessary clearance when using high lift camshafts.
The advanced analysis of the material properties found that the oval design of the Tomei pistons were ideal for both thermal expansion and head dissipation. Clearance is maintained in each cylinder at an optimum level to maximize power output, without additional friction, operational noise or blow-by gases. Our piston manufacturing technology is the most advanced and an industry leader in Japan.
The thin rings help reduce unwanted friction and fluttering. The reduced thickness means a reduction in inertial force, which reduces blow-by gases. The distance between the pin and crown allows the design for the ideal land thickness and design shape. This dramatically maximizes the pistons strength.
The ultimate strength and ideal weight was achieved with our specific design to suit the harsh conditions that the RB26 will see during use.
