Turbosmart TS-1 Turbo 6870 (Kompact) T4 Divided - 1.00 A/R for External Wastegate

The Turbosmart TS-1 6870 Kompact is a high-performance turbocharger developed for motorsport and advanced performance builds. It combines modern engineering, advanced materials and lightweight construction to deliver quick response, efficient airflow and high power potential.

The TS-1 series is oil-cooled and features a dual ceramic ball-bearing system and a specially developed bearing and shaft assembly with low rotating mass. Combined with the advanced compressor design, this helps deliver rapid boost build-up and strong performance, even at lower turbo speeds.

This Kompact version features a divided T4 turbine inlet, which separates exhaust pulses from different cylinder groups up to the turbine wheel. It is designed for exhaust manifolds with divided exhaust flow and can contribute to more efficient turbine operation when the system is properly designed. The turbocharger features a 1.00 A/R turbine housing and is designed for use with an external wastegate.
