Details
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.
