HKS has redesigned VR38DETT 4.1L Kit to upgrade kit to 4.3L Kit. This kit is available from street use to circuit use. Kit Contents:
Billet Piston kit + H-Beam Connecting Rods (STEP3) + Billet Crankshaft.


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)



 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
  • 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.
 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.
