Unlock the true potential of your RB26 engine with the Tomei Forged Piston Set, available at Terra Firma Automotive. These 87mm pistons are designed for maximum strength and durability, using a high-strength forging method rather than the traditional casting process used in commercial vehicles. Built to handle the high combustion pressure of tuned engines, these pistons are optimized for both performance and weight reduction.
Tomei achieves this by minimizing excess material and using exclusive forged materials, ensuring that the pistons maintain strength while reducing weight. The piston walls are thinner to maximize efficiency without sacrificing reliability. The pistons feature an oval barrel shape, engineered with precise thermal expansion calculations for optimal clearance and smooth movement under high-performance conditions. The piston recess is designed to support 1mm oversized valves, further enhancing your engine's power output.
To reduce friction loss, Tomei thins the piston rings, ensuring smoother operation and increased longevity. Each set comes complete with pins, clips, and rings designed specifically for this model. Experience superior performance with the Tomei Forged Piston Set, crafted for those who demand the best from their RB26 engine.
