A fixed scroll compressor body includes a scroll compressor body casting. The casting has a central body portion having a plate-like base with a spiral scroll rib projecting from the base at a right angle thereto. The spiral scroll rib includes a volume between the spiraled ribs for the compressing of refrigerant. The spiral scroll rib spirals from a central region of the plate-like base to an outer wall of the central body portion. The casting further includes a first inward-protruding portion that protrudes from the outer wall into the volume. A distance that the first inward-protruding portion protrudes into the volume is greater than a thickness of the first inward-protruding portion such that removal of the first inward-protruding portion results in a first intake opening in the outer wall. The first intake opening provides a path for a flow of refrigerant into the volume.
