Description
HKS has redesigned the VR38DETT 4.1L to increase it up to 4.3L capacity. This 4.3L kit is available for street-to-circuit use.
Redesigned features:
- Higher Torque – Allowable Torque: 150kgm
- Low Vibration – Equivalent Level to the Stock
- Longer Stroke – Stroke: 99mm（the world’s longest level）
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 for high-rate combustion.
Connecting Rods
- The connecting rods were designed specifically for this kit.
- Engine modifications are minimized.
Crankshaft Stroke – 99.0ｍｍ
- 9.0mm stroke without bore size change is incomparable.
- Billet Crankshaft
- The vibration generated from the V6 engine is reduced to a degree that is not annoying by precise balance adjustment. (The included parts must be used together）
- The structure was designed to reduce the load on 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 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.
