    • HKS VR38DETT 4.3L Step Pro complete motor launching this year from HKS USA

      The Nissan GT-R certainly does not suffer from tuning options. Heck, if you want a completely built off the shelf 4.3 liter VR38DETT that plugs right in you can have that as well. HKS USA will be releasing this 4.3 liter Step Pro motor later this year.


      VR38DETT 4.3L KIT complete engine with strengthened crankshaft and main bearing for high torque.

      • Nitrided Steel Crankshaft. Heat treatment for improved durability.
      • Enlarged Crankpin Sidewall Radius to improve torsional strength
      • Developed at HKS Original Oversize Main Stud Bolts
      • #2 and #3 Journal made of Chrome Molybdenum for improved durability
      • Line boring to ensure journal roundness
      • Beryllium valve seat and phosphor bronze guides to improve heat transfer
      • Crank damper for VR4.3 to decrease torsional vibration

      * To be released August 2020



      They get to 4.3 liters with a very aggressive stroke increase:
