Unit price  per 

The Garrett GTX2860R Gen II supercore is a complete ball-bearing turbocharger supplied without a turbine housing, so you can pair it with the GT28R / GTX28R housing that suits your setup, or reuse the one you already have. Garrett rates it at 200–475 hp for engines from 1.4 to 2.5 litres.

Gen II compressor wheel aerodynamics deliver up to 20% more power than the original GTX2860R, while a fully machined ported shroud improves surge resistance for crisp, responsive boost.

Key features

  • Gen II forged, fully machined compressor wheel aerodynamics
  • 8 mm dual ceramic ball bearing cartridge, oil and water cooled
  • Fully machined compressor inlet, outlet and ported shroud
  • High-flow Gen II compressor housing
  • Fully machined speed sensor port (plugged from factory), accepts the Garrett speed sensor kit, sold separately
  • Outline-interchangeable with GT and GTX Gen I turbos, so it suits existing piping
  • Compatible with all existing GT and GTX (GT28R / GTX28R) turbine housing kits

Please note: turbine housing is not included. Product photos show the turbo with a housing fitted. Standard rotation. Maximum allowable shaft speed is 185,000 rpm.
