Capacity upgrade kit brings the best of tuning to the legendary v6 and focuses on engine response and pleasure of driving.

Includes Piston Kit, Connecting Rods and Crankshaft.

Piston Kit

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.

Connecting Rod

The connecting rods were designed specifically for this kit. Engine modification is minimized.

Crankshaft Stroke - 99.0mm

99.0mm 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.

Compatible with Stock Bore Size - 95.5mm

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.

Special Oil Jet

A special oil jet to cool down the pistons to the optimum level is newly designed.

Features:

• 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
• A special oil jet cools down the pistons to the optimum level
• Higher Torque - Allowable Torque: 150kgm
• Low Vibration - Equivalent Level to the Stock
• Longer Stroke - Stroke: 99mm

Fits:

• 2008+ Nissan GT-R (VR38DETT)

Notes:

• Boring Honing is required.
