HKS GT TURBINE

The selection of universal turbochargers from 500ps to over 1000ps has been developed.


  • GT75115_BB

  • GT75100_BB

  • GT6290_BB

  • GT5565_BB

  • GT4950_BB

Concepts

  • Big turbocharger for inline 6, V8, V6 and inline 4 tuning engines.
  • HKS takes on the challenge of reaching high power zones that have not been covered previously.
  • The turbo system offers a comprehensive application in some of fields, such as drag racing, drifting and track time attack.

Features

  • Compared to previous HKS turbochargers, this turbocharger provides a massive charging air flow despite the small diameter of both compressor/turbo wheels.
  • The V-band turbo housing is made of stainless steel. (*Material may vary from model to model.)
  • Recommended for those who use big singles for track day.
  • CHRA Bearings are ball bearings.
  • The GTIII-5R and 4R designs have a machined aluminum ported shroud that combines the bell mouth design and T51R type recirculation channel to provide both anti-surging and smooth intake air flow.
  • A special, highly corrosion-resistant matt black coating treatment on the surface of the compressor housing prevents aluminum corrosion over time. It also combines with a champagne gold anodized ported shroud to unify the design exterior.
  • High corrosion resistant anodized aluminum coating (Matt Black)

  • Machined aluminum ported shroud (Champagne Gold)

  • T51R type recirculation channel

[ Highly corrosion-resistant matte black coating treatment]

  • A highly corrosion-resistant matt black coating treatment is applied to protect the exterior of the compressor housing from corrosion.
  • This coating is a surface treatment with the ability to provide no surface corrosion even after 240 hours in accelerated corrosion tests.(combined cycle)

*In-house data

[ Bellmouth shape ported shroud ]

  • The ported shroud design inherited from the TO4Z and evolved in the GTIII-4R and 5R.
  • The standard ported shroud has a piped inlet, but the bell-mouth shaped intake air flow channel with a wide inlet diameter is shaped as a "hole" to allow intake air to be taken in through the suction pipe.
  • The structure also makes it easy to produce the turbo spool sound, also known as the 'T51R sound'.

*The volume and sound of the intake sound differs depending on the model. *All models have HKS ported technology.

Series Lineup

[ Origin of the model name ]

The model name is based on maximum output (compressor side) and turbine wheel diameter.

[ Compressor map ]

Wide maximum efficiency range extending from low boost pressures with a pressure ratio of 2 to high boost pressures with a pressure ratio of 3. Growth potential at high boost pressure.

GT75115_BB

[ GT75115_BB ]

  • Assumed outputs
    1100ps
  • Engine
    RB26 (2.8L) / 2JZ (3.4L)
  • Features
    Assuming high boost with the aim of 1000ps OVER, the compressor is V-band.

GT75100_BB

[ GT75100_BB ]

  • Assumed outputs
    1000ps
  • Engine
    RB26 (2.8L) / 2JZ (3.4L)
  • Features
    Aimed at 1000ps. with the same spool-up as the T51R SPL.BB with boost keeping at high rpm.

GT6290_BB

[ GT6290_BB ]

  • Assumed outputs
    900ps
  • Engine
    RB26 (2.8L) / 2JZ (3.4L)
  • Features
    Turbo characteristic between the GTIII-4R and the GTIII-5R; intercept is shifted to the high rpm side compared to the 4R, but there is no sagging at high rpm and maximum output is improved.
