HKS Connecting Rod Set FA20 Step 1

POINT-1:PISTON KIT

• Carefully selected specially forged raw materials used.
• Replacing the gasket enables both NA and turbo-charged engine users to use this kit.
• In order to cope with the demands of high outputs, strength analysis and tests have allowed optimisation of compression ratio for flexibility of setup and high boost use.
• Piston crown had 3D design in consideration of stock direct injection system.
• Stock pistons skirts overhang from the block during bottom of travel. Short height pistons have revised potential issues in this area.
• Friction, weight and other design properties to suit the needs of short height pistons.

POINT-2:CONNECTING ROD

• Specific connecting rods have been designed to suit the longer stroke.
  With no engine modifications, a special size crank pin has been set requiring new bearings.　
  ※The crank metals (Nissan RB26 & SR) must be purchased separately.
• High strength I beam design and revised connecting rod bolt size.

POINT-3:CRANKSHAFT STROKE 90.0mm

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

POINT-4:Stock Bore Compatible　86.0mm

• In order to maintain the engine block strength, the stock bore size is maintained meaning there is no need for cylinder liners
• Reduces the cost of installation as liners, bore & hone and block facing processes are unnecessary.
