【CAPACITY UPGRADE KIT RB26 2.8L STEP2 BCD】
Based on the 2.8L STEP2 kit and upgraded with lightweight, high-rigidity forged "BCD" pistons.
BCD = A bridge design is a truss structure that is employed at the back of the piston to enhance the rigidity of the piston.

|Compression Ration (t=1.2)
1. Piston Kit, Piston weight: 334g Piston Pin weight: 97g
- Lightweight A2618 aluminum alloy billet piston with high temperature strength
- Bridge design improves structural rigidity.
- Profile optimization has shortened the Piston skirt height and reduced weight.
- Short piston pit with lightweight boss part.
- 2 layers of molybdenum coating to eliminate friction and improve initial functionality of the whole system.
2. Crankshaft Stroke 77.7 mm
- Billet full counter crankshaft
- Counterweights are efficiently located to decrease overall weight and improve overall balance.
- Response is improved by reducing the weight of the pin journal and the center section by cutting the core of the pin journal to reduce the weight.
3. Connecting rods
- Nickel Chrome Steel Billet H-Beam Connecting rods.
- WPC treatment to improve strength
