To provide a housing for a turbosupercharger which reduces the total weight of a vehicle.
The housing for a turbosupercharger includes a housing shell 17 which at least partially surrounds a rotor space 15, at least one manifold 3 of a combustion engine 2, a pipe connecting the housing shell to at least one manifold of the combustion engine, and a cylinder head 20 of the combustion engine. All of these component parts are integrally cast as one piece. This is performed according to a method comprising the steps of connecting and bonding a sand core for a part of the housing shell of the turbosupercharger to a sand core for forming a space of the manifold, and then connecting and bonding the cores to a sand core for forming the cylinder head. Subsequently, the connected and bonded sand cores are inserted in firmly interconnected casting molds with which a part of the housing shell of the turbosupercharger, the manifold and the cylinder head are respectively casted, and molten metal is poured in the casting molds so as to be solidified.
