| Product Description | Capacity: 2.116L Type: 86.5-22 Boring: Needed Full Flow Processing: Not Needed Compression Ratio: 10.4 (t=0.84) Description: The era of high supercharging tuning for direct injection engines has arrived!We have added a 0.5 oversize 2.2L KIT to the 2.1L LOW COMP KIT for FA20.Many people have installed a supercharger on their FA20.These people developed a high-strength low-compression piston, which is necessary when moving to higher supercharging.POINT-1 Piston kitAdopts forged material to improve strength.A cavity is provided on the crown surface to optimally atomize direct injection.A 3D shape that maintains a tumble flow on the crown surface.Recessed shape designed for use with HKS camshafts.By selecting gaskets, we have expanded the range of compression ratio settings.By adopting a two-layer molybdenum coating, we have achieved improved seizure resistance and reduced friction.POINT-2 ConrodSTEP2Through strength analysis, we optimized the wall thickness, minimized weight increase, and achieved an approximately 30% increase in strength.We have adopted an I cross-sectional shape with an emphasis on increasing buckling strength.In order to achieve the ideal shape with no waste material and to eliminate any points of failure on the surface, the product is manufactured by completely machining, and the surface is subjected to strong shot peening treatment to improve fatigue strength.We applied the optimal heat treatment to chrome molybdenum steel to achieve both increased strength and toughness. |
