Product Details
The Turbosmart TS-2-6870B-T4082E TS-2 6870 Kompact Turbocharger is engineered for serious performance applications where high horsepower capability, rapid transient response, and durable construction are essential. This specific 6870 configuration features a 68mm compressor inducer, 70mm turbine exducer, T4 turbine inlet, 0.82 A/R turbine housing, 3-inch V-band turbine outlet, and external wastegate configuration. Turbosmart rates the TS-2 6870 for approximately 850–990 horsepower, making it a strong choice for high-output street, drag, roll-racing, and competition builds.
Turbosmart's TS-2 series combines an oil- and water-cooled center housing with a proprietary dual ceramic bearing system and ultra-low-mass rotating assembly. Aggressive compressor aerodynamics help the turbo respond efficiently at lower shaft speeds, while the turbine system is engineered to maintain airflow and power as exhaust flow increases. The result is a turbocharger designed to deliver both strong response and substantial top-end power rather than sacrificing one for the other.
Premium materials are used throughout the TS-2 platform. The 6870 incorporates a 7+7 splitter-style compressor wheel manufactured from 2618 aluminum, a lightweight aluminum compressor cover, a 310S stainless-steel investment-cast turbine housing, and a 713C Inconel turbine wheel capable of operating in demanding high-EGT environments. Each unit is also VSR speed-balanced for smooth, reliable operation at extreme turbocharger shaft speeds.

6870 Kompact Performance
- The 6870 Kompact combines a 68mm compressor with Turbosmart's 70mm turbine platform to provide the airflow needed for applications approaching four-digit horsepower while maintaining a relatively compact package. Turbosmart's published operating range of 850–990 HP positions this turbo for serious engine combinations where response and top-end airflow are equally important.
- Actual power and spool characteristics will vary according to engine displacement, compression ratio, cylinder-head flow, camshaft selection, exhaust manifold design, fuel type, boost pressure, intercooling, exhaust backpressure, and engine calibration.
T4 0.82 A/R Turbine Housing
- Part number TS-2-6870B-T4082E specifically identifies the T4, 0.82 A/R, externally wastegated version of the TS-2 6870 Kompact. Turbosmart also offers the 6870 with other turbine housing configurations, including T4 0.96 A/R, divided T4, and V-band options, making the complete part number important when selecting the correct turbocharger.
- The 0.82 A/R single-scroll T4 turbine housing is particularly attractive for builds seeking strong response while retaining the flow capacity of the 70mm turbine. The 3-inch V-band turbine outlet provides a compact and secure connection for a fabricated downpipe. Because this version is externally wastegated, boost control is handled by a separately installed external wastegate, allowing the builder to choose wastegate size and placement for the particular engine and manifold configuration.
Oil & Water-Cooled TS-2 Design
- Unlike Turbosmart's TS-1 oil-cooled turbochargers, the TS-2 series incorporates both oil lubrication and water cooling. The coolant circuit provides additional thermal management for the center housing, an important advantage in applications subjected to repeated high-load operation and elevated exhaust temperatures.
- Turbosmart supplies its TS-2 turbochargers with the necessary installation components, including gaskets, oil feed and drain fittings, and water feed and return fittings, helping simplify integration into a properly designed custom turbo system.
Installation & Application
- The TS-2-6870B-T4082E is a universal performance turbocharger, not a vehicle-specific bolt-on replacement. Installation requires a compatible T4 exhaust manifold, appropriately sized external wastegate, fabricated downpipe, charge piping, oil feed and drain plumbing, and coolant feed and return plumbing.
For high-output builds seeking a balance between response and serious power capability, the Turbosmart TS-2-6870B-T4082E 6870 Kompact delivers an impressive combination of an 850–990 HP operating range, T4 0.82 A/R hot side, 68/70mm wheel combination, dual ceramic bearings, Inconel turbine construction, and oil-and-water cooling in a compact, motorsport-focused package.
