KDM Tuners source listing

Choose the major parts for a Theta II engine build in one kit. KDM combines forged pistons, connecting rods, bearings, gaskets and studs, with sleeve and valve-spring options for the planned specification.

Fitment & application
  • KDM lists this Theta II parts kit for Elantra N, Kona N and Veloster N engine builds. Confirm the exact engine, model year and transmission before planning a build.
  • Not a universal Hyundai/Kia 2.0T kit. No compatibility is established here for Genesis, non-N engines, 1.6T engines or electric N models.
Features & specifications
  • Five configuration choices: sleeves, valve springs, piston compression, rod type and head-stud option.
  • 86.5 mm Traum pistons: 9.5:1 or 10:1 compression; KDM identifies 9.5:1 as the original ratio.
What is included
  • Selected Traum pistons and Molnar or Manley connecting rods.
  • ACL main, rod and thrust bearings.
  • Theta OEM rebuild gasket kit.
  • ARP upgraded 10 mm main studs and the selected head-stud option.
Required parts & machine work
  • Professional engine assembly and specification checks.
  • Darton sleeves and SuperTech/GSC valve springs are optional; select them explicitly.
  • Plan machining, fueling, turbo hardware and calibration with the engine builder.
Important product notes
  • This is a parts kit, not an assembled engine or installation service.
  • KDM says builds above 600 hp need sleeving and additional supporting modifications; supplier performance claims do not guarantee output.
  • Confirm stud dimensions and installation details with the builder: the source stud paragraph is ambiguous.
Supplier production notes
  • KDM warns that unavailable components may require 4–8 weeks to be made. This supplier estimate is not an RVE dispatch promise.

Supplier guidance is not an RVE dispatch or delivery commitment. Confirm timing with RVE before ordering.
