The era of highly boosted tuning for direct-injection engines has arrived!

The low compression type FA20 2.1L Kit is available for high boost tuning.

Upgrading with forced induction is very common for the FA20 engine tuning.

HKS has developed a highly durable low compression piston required to move onto the next tuning level.

■ FEATURES

POINT① Piston

• Forged material improves durability.
• The cavity on the piston head optimizes the atomization of fuel by direct injection.
• 3D Piston crown design sustains tumble flow.
• The piston is recessed to match with high lift HKS camshafts.
• Depending on the thickness of the gasket used, the setting range of the compression ratio can be expanded.
• Molybdenum coated pistons reduce friction.

POINT② Con Rods

• Cracked core rods have been designed to suit the longer stroke.
• Special size crank pins are used, and engine modifications are not required.
• *Nissan genuine bearing for RB26 and SR must be purchased separately
• High strength I-beam design and revised connecting rod bolt size.

POINT③ CRANKSHAFT STROKE 90.0mm

• Made of HKS special forged materials.
• Perfect pin journal size was selected by meticulous analysis and experiment for extended stroke.
• Carefully designed weights balance the engine for maximum efficiency.

POINT④ Stock Bore Compatible 86.0mm

• The bore size is the same as stock to maintain the engine block strength.
• Cost effective: No need for boring, honing, and purchasing parts such as cylinder liners.
