HKS 21004-AN019 Stroker Kit 4.3L VR38DETT 99 mm Stroke for NISSAN GT-R (R35)

Description HKS 21004-AN019 Stroker Kit 4.3L VR38DETT 99mm Stroke for NISSAN GT-R (R35)

The HKS 21004-AN019 4.3L stroker kit is an advanced upgrade for the VR38DETT engine, evolving from the previous 4.1L configuration. Designed for applications ranging from street performance to full circuit use, this kit delivers significant gains in torque output and engine responsiveness while maintaining optimal reliability. The redesigned components enable an allowable torque capacity of 150 kg·m, minimal vibration comparable to OEM levels, and an extended 99 mm stroke—one of the longest available for this platform.

• Billet pistons with optimized geometry, featuring a reinforced truss structure for ultra-lightweight strength and efficient combustion via a dedicated squish area
• Custom connecting rods engineered to minimize engine modification requirements
• Billet crankshaft with 99 mm stroke, precision balanced to reduce V6 vibration and maintain bearing durability under increased torque
• Retains stock bore size (95.5 mm) for maximum block rigidity and ideal heat dissipation without liner modification
• Specially designed oil jet system for optimal piston cooling

Specifications:

• Bore: 95.5 mm
• Stroke: 99.0 mm
• Compression Ratio (t=0.8): 8.6
• Maximum Tolerable RPM: 7400 rpm
• Displacement: 4255 ml
• Allowable Torque: 150 kg·m
