Once received, they are disassembled and fully inspected. \n\t\tThe compressor cover and center cartridge are then machined to accept our 5-axis CNC-machined impeller wheel. Externally, no changes \n\t\tare made, preserving a completely stock appearance. The new impeller wheel supports greater power levels than the factory unit with \n\t\tlittle to no sacrifice in spool or response. The turbochargers are then reassembled with new seals and fully balanced for smooth \n\t\toperation and OEM service life. All original oil and coolant lines bolt right up, making for a simple install.\n\t\t\u003cbr\u003e\u003cbr\u003e\n\t\tIf you prefer not to send in your turbos first, a core exchange option is available. With this option, upgraded turbochargers are \n\t\tshipped to you up front for a refundable core charge. We refund the core charge once we receive your factory turbo units and they pass\n\t\tinspection.\n\t    \u003c\/p\u003e\n\t\u003c\/div\u003e\n\n\t\u003cdiv\u003e\n\t\u003cimg loading=\"lazy\" src=\"graphics\/00000001\/s\/5\/s55_w3turbo_3.jpg\" alt=\"side by side comparison of the Weistec W.3 Turbo Upgrade for the BMW S55 and the factory turbo unit\"\u003e\n\t\u003c\/div\u003e\n    \u003c\/div\u003e\n    \n    \u003cdiv class=\"rflex-container\"\u003e\n    \n      \u003cdiv\u003e\n        \u003cimg src=\"graphics\/00000001\/s\/5\/s55_w3turbo_2.jpg\" alt=\"side by side comparison\"\u003e\n      \u003c\/div\u003e\n    \n      \u003cdiv\u003e\n            \u003cbr\u003e\n        \u003ch3\u003eMaximum Performance.
