TOMEI Forged Piston Set (87.00mm Bore, 30.00mm Compression Height) Compatible with Nissan RB26DETT (GT-R R32/R33/R34) - Fits Standard Stroke & 2.8L Stroker Builds

Rebuild your RB26DETT with a high-performance foundation using this versatile TOMEI Forged Piston Set. Engineered for both standard stroke and 2.8L stroker applications , these pistons feature an 87.00mm bore size (+1.0mm oversize) and a 30.00mm compression height. They are compatible with the GT-R BNR32, BCNR33, and BNR34, providing a robust and durable upgrade for high-horsepower builds requiring an overbore using either the factory crankshaft or a 2.8L stroker kit. Manufactured using a high-strength forging process, these pistons offer superior high-temperature strength and durability compared to cast OEM pistons. This allows for reduced weight and thinner walls without compromising strength, lowering reciprocating mass for improved engine response. Each piston features a precision 3D profile (oval barrel shape) engineered with calculated thermal expansion to maintain optimal cylinder clearance. The set includes piston rings, pins, and clips for a complete drop-in assembly solution.

• Dual-Application RB26 Pistons 87.00mm bore: Forged pistons with 87.00mm (OEM +1.0) bore and 30.00mm compression height, specifically designed to work with both standard stroke and 2.8L stroker crankshafts in GT-R (R32, R33, R34) applications.
• High-Strength Forged Construction: Manufactured using an advanced forging process for superior durability and high-temperature strength, allowing thinner, lighter walls that reduce reciprocating mass without compromising reliability.
• Optimized 3D Skirt Profile: Features precision-engineered oval barrel shape with calculated thermal expansion characteristics, ensuring smooth piston movement and optimal cylinder clearance at all operating temperatures.
• Performance-Ready Design Features: Valve pockets accommodate 1mm oversized valves for cylinder head upgrades, while ring grooves are designed for thinner piston rings to reduce friction loss.
• Complete Drop-In Assembly Kit: Includes perfectly matched piston rings, high-strength wrist pins, and precision wire locks—all components needed for a reliable, high-performance engine assembly.
