Vehicle Fitment
- Porsche 996 Turbo
- Porsche 996 GT2
- Porsche 997.1 Turbo
- Porsche 997 GT2
Included Components
- 6 x Forged pistons (3x Left-Hand / 3x Right-Hand), 23mm pin, 9.4:1 compression ratio, 427g each
- 6 x Steel liners, Ø102mm bore, Ø107mm spigot (direct fit, no block modification required), 3746cc total displacement
- 6 x Piston ring sets
- 6 x Piston pins (23mm)
- 12 x Circlips for piston pins
Features
- Nikasil-coated forged alloy barrels / steel liners providing excellent sliding characteristics
- Optimized pistons produced with special forge tooling
- Desaxes (offset) pin design for LH/RH fitment reduces piston wear and engine noise by shifting contact side before TDC during compression buildup
- Weight and center of gravity optimized via FEM (Finite Element Method) calculations
- Special bridged piston design enhances stability and longevity
- Sophisticated milling and treatment reduce piston weight
- Deeper valve pockets (inlet large / outlet small) for compatibility with high lift camshafts
- Special piston rings engineered to reduce oil consumption and blowby
- Compatible with VarioCam Plus system
- Most effective and efficient power upgrade for maximum power, torque, and agility
- Developed and tested on RS-Tuning dynamometer
Performance Benefits
- Significant power and torque increase
- Enhanced engine durability and reliability
- Reduced noise and wear thanks to advanced pin offset design
- Weight optimized components for improved engine dynamics
- Precision fit with no block modifications needed
