HKS GT TURBINE
[ HKS GT TURBINE SERIES ]
The selection of universal turbochargers from 500ps to over 1000ps has been developed.
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.

[ 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.

[ 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.
