The Hunter is the next evolution for the GT series journal bearing This is in the same class as the GT3071- GT3076R Garrett mid-framed T3 footprint. At approximately 51lbs/min, The Hunter gives 1.8-2.4 litre 4-cylinder and 2.5 litre 6-cylinder engine applications the ability to be as responsive as the GT3251B cast unit, and still make over 460whp with its well-matched turbine exhaust wheel and ported turbine housing in a T31 footprint, in fantastic compact package that does not overfill the engine bay.
With its T6 -7075 forged aluminum composition, The Hunter has unsurpassed durability to prevent compressor wheel flex that is a typical issue with other "billet" aluminum wheels that are of a lower strength composition. As with all of the STC Forged aluminum series, this turbo gives the reliability, repeatability, and rebuildability that is expected from Genuine Garrett Products
This unit has a standard Journal Bearing T31 2.5" turbine housing configuration, which can easily replace the standard T3/T4 Garrett-based turbocharger, and is available in T3 or T4 3" V-band configuration.(Coming Summer of 2018)
The use of 3/8th NPT water fittings for the Journal Bearing version is optional, but highly recommended for those using this turbocharger for "daily driving" duties in which oil temperatures and pressures are put to the test.
The Ball-bearing version is optional for an additional charge, and requires the use of a restrictor (.030") and water fittings. *
This particular turbocharger is designed best for engine applications that generally plan to run efficiency ranges from 10psi-25psi that plan to run from 300whp-460whp in the standard T04E compressor cover. The video below is for the optional T04B compressor cover. Photos shown above are in T04B & T04E compressor covers that have optional coatings.
Please note: As of 11.5.2015, due to increased cost, the T04B compressor cover option is a cost upgrade and not a standard as stated in the video. Main photo shown with Garrett® logo stamped is the Hunter with our T04B compressor cover option
The Hunter comes standard with a T04B 2.75" inlet as the compressor cover.
All Journal Bearing turbos use optional water-cooling ports. These are not required for the turbocharger to work but is highly recommended.
Important Sizes and information to note:
Water Ports = 3/8NPT
Oil feed fitting size 1/8NPT
Recommended Restictor = .060"-.065" for oil pressures over 75-80psi oil pressure
All Ball-bearing turbos use required water ports in order to function properly, and share the same oil feed and fitting size as the Garrett GT and GTX series
Water Ports = 14mm
Oil Feed Fitting size = 7/16
Recommended restrictor = .030" for oil pressure over 75psi
