This T3 & T4 platform utilizes similar abilities as the Interceptor R (GT3588R), in a journal bearing package w/ options to upgrade to a Garrett Ball-Bearing CHRA.  At approximately 70lbs/min, The Interceptor gives 1.8-2.4 litre 4-cylinder and 4.0 litre engines to make over 730whp with its well-matched turbine exhaust wheel and ported turbine housing in a T31 footprint, or GT3582R foot print.  The compressor wheel fits in Garrett's T04S standard and GT35R ported-shroud compressor covers.

With  its T6 -7075 forged aluminum composition, The Interceptor is contstructed  to not only prevent compressor wheel flex that is a typical issue with other "billet" aluminum wheels that are of a lower strength composition, but was especially created to be utilized with higher rotational speeds associated with circuit racing and other forms of high endurance racing. As with all of  the STC Forged aluminum series, this turbo gives the reliability, repeatability, and rebuildability  that is expected from utilizing 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 configuration or T4  3" V-band configuration. 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.

As a ball-bearing package, instead of the 3/8th NPT fittings, The Interceptor uses the same 14mm water fittings that are used on the GT(X)25R-GT(X)35R steel dual ball-bearing cartridge, and requires the use of a restrictor (.030") and water fittings for proprer operation. *

This particular turbocharger is designed best for engine applications that generally plan to run efficiency ranges from 15psi-38psi that plan to run from 460whp-750whp  in the standard T04S compressor cover, (Ported Shroud T04R cover is an option for a small additional charge) and comes in a  T3 .63A/R or .82A/R Turbine housing . T4 Options include Open .68 A/R, .84 A/R, and .96 A/R in the 3" V-band downpipe flange.  Divided housing options are 1.00 A/R and 1.15 A/R. in a 4 inch V-band downpipe flange configuration. 

We also offer a turbine housing utilizing a TiAL-flanged V-band turbine inlet & V-band turbine outlet in .82A/R turbine housing for the 74mm exhaust wheel.

All Journal Bearing CHRAs use optional water ports.  These are not required in order for the turbocharger to operate, but they are highly recommended for optimal performance and longevity


Important Fitting Size Information

Water Ports = 3/8NPT (recommended to -6AN)

Oil Feed Fitting Size = 1/8NPT

Recommended Restrictor = 0.060"-.065" for oil pressures 75psi-80psi+


Return Flanges

For both Journal Bearing and ball-bearing turbochargers, return flange is still 1/2 inch flanges used on standards T3/T4 turbochargers except for the GT and GTX Series turbos


T4 Turbine Housing Option

If T4 turbine housing is selected, 74mm Diameter exhaust wheel is standard on T4 Journal Bearing and Ball-Bearing turbochargers except for GT Applications.


Oil Feed Fitting Differences

Oil / Water Cooled Journal Bearing Turbos - Oil Feed = 1/8NPT

Oil Cooled Journal Bearing Turbos  - Oil Feed = 1/4thNPT

Ball-Bearing Turbos - Oil Feed = 7/16 -24
