Tomei Forged Piston Kit – Mitsubishi 4G63-22/23, 86.0mm bore

Description

Since the piston is one of the most important components, Intake, 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 stress when used, Intake, highly modified engines that produce over 100 horsepower per cylinder.

By using forged metal made from aluminum alloy to construct our 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, Intake, highly tuned RB26 and SR20 engines are the same type of pistons used, Intake, Group C and F1 racing.

Please Note: Not compatible with standard crankshaft! Tomei recommends the Tomei Forged Full-Counter Crankshaft 4G63-23 (SKU T-121044).
