HKS has redesigned VR38DETT 4.1L Kit to upgrade it to 4.3L Kit.
This kit is available from street use to circuit use.
The following is the main redesigned features:

1) Higher Torque - Allowable Torque: 150kgm
2) Low Vibration - Equivalent Level to the Stock
3) Longer Stroke - Stroke: 99mm
(the world's longest level)

Features<POINT-1>?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.

<POINT-2>?Connecting Rod

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

<POINT-3>?Crankshaft Stroke - 99.0mm

  • 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.

<POINT-4>?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.

<POINT-5>?Special Oil Jet

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