FEATURES

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.
