HKS 4.3L Crank Shaft VR38 Nissan GT-R 2008

HKS has redesigned VR38DETT 4.1L Kit to upgrade it to 4.3L Kit. This kit is available from street use to circuit use.

Features:

• Higher Torque - Allowable Torque: 150kgm
• Low Vibration - Equivalent Level to the Stock
• Longer Stroke - Stroke: 99mm (the world's longest level)
• The billet-pistons have the ideal piston shape.
• The special truss shape enhances the durability and makes ultra-lightweight pistons.
• A squish area allows high rate combustion.
• The connecting rods were designed specifically for this kit. Engine modification is minimized.
• 9.0mm stroke without bore size change is incomparable.
• Billet crankshaft.
• The vibration generated from V6 engine is reduced to the degree to be not annoying by precise balance adjustment. (The included parts must be used together.)
• The structure was designed to reduce a load to the metals so it can withstand the increased load to the main metal due to higher torque.
• High efficiency heavy metal made balance weight reduces the weight and achieves high engine response.
• The bore size is the same as the stock size to maintain the engine block rigidity and the ideal heat conduction for the optimal engine performance.
• Modification of liner is not necessary so the cost related to this liner modification can be saved.
• A special oil jet to cool down the pistons to the optimum level is newly designed.
• A billet-piston with squish area allows better combustion.
• A billet-crankshaft with high efficient balance weight reduces vibration, improves engine response, and decreases the weight.

• Bore - HKS 4.3L Kit: 95.5mm/Stock: 95.5mm
• Stroke - HKS 4.3L Kit: 99.0mm/Stock: 88.4mm
• Comp. ratio (t=0.8) - HKS 4.3L Kit: 8.6/Stock: 9.0
• Tolerate RPM - HKS 4.3L Kit: 7400rpm/Stock: 7000rpm
• Displacement - HKS 4.3L Kit: 4255ml/Stock: 3799ml
