HKS 4.1L Kit

HKS has developed upgrade kit for R35 GT-R for some more power! People who are not satisfied with 800+ and want more power on R35, this is the kit you need. We have made it for a longer stroke to gain on the lower RPM for the big turbine. So you can have absolute power even on the normal RPM. This high-end, made in Japan products of piston, conrod and crankshaft are made by billet method.


  • POINT 1. Piston Kit
    • HKS were insistent on forging, we employed billet method from forged bar material.
    • We have employed special truss shape with our test and strength analysis for an extreme power.
    • The perfect shape of very short height low friction type gives light weight and strength. They are 80g lighter compared to the stock and STEP1/STEP2 piston.
  • POINT 2. Connecting rod
    • Being a longer stroke, we have developed original conrod. For modification work of engine side is needed only at the block oil return.
  • POINT 3. Crankshaft stroke 95.5mm
    • Billet method form forged bar material.
    • HKS special shape that came from our profound racing experience analysis on V6 balance.
    • For better friction we have employed special edge for counter weight.
    • We have designed counter weight for the perfect shape for a perfect balance!
  • POINT 4. Normal bore compatible 95.5mm
    • Not to decrease the strength of the block which relate directly to the engine's performance, HKS has employed stock bore size that does not need liner process.
    • Also we could cut the cost by not having liner work and block shaving of upper surface.
  • POINT 5. Only HKS can provide the high quality total setup package kit.
    • This kit is for upgrade from 800+. Surge tank, injector kit, intercooler and etc.are offered separately for a total tuning solution.
    • HKS have tested our products over and over in the bench or circuit for the best performance and safety.
