Spiral-shaped turbine housing for exhaust-gas turbocharger of internal combustion engine, is designed to accommodate turbine wheel and inserts, where inserts are used for influencing flow parameters at wheel outlet and/or wheel inlet

The housing (40) is designed to accommodate a turbine wheel (42), a housing insert (44) and a lambda-shaped grid insert (46), where the housing insert and the grid insert are used for influencing flow parameters at a turbine wheel outlet and/or a turbine wheel inlet. The housing exhibits a multi-flow design and is designed as a base turbine housing. The housing insert includes an inner contour to influence one of the flow parameters at the turbine wheel outlet. The housing insert or the grid insert is formed as a single piece. Independent claims are also included for the following: (1) a turbine kit system comprising a set of turbine wheels (2) a compressor housing for an exhaust-gas turbocharger of an internal combustion engine (3) a housing insert for a compressor housing, comprising shovels (4) a compressor kit system comprising a compressor housing (5) an exhaust-gas turbocharger kit system comprising a base-bearing device. Die Erfindung betrifft ein Abgasturboladerbaukastensystem (32) mit einem Turbinengehäuse (40) als Basis-Turbinengehäuse (40), mit einem Verdichtergehäuse (50) als Basis-Verdichtergehäuse (50), mit einem Turbinenbaukastensystem, mit einem Verdichterbaukastensystem und mit einer Basis-Lagervorrichtung (52).
