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 inspection.\n\t    \u003c\/p\u003e\n\t\u003c\/div\u003e\n\t\n\t\u003cdiv\u003e\n\t    \u003cimg loading=\"lazy\" src=\"graphics\/00000001\/m\/1\/m177_178_w.3_7_1.jpg\" alt=\"Weistec W.3 Turbo Upgrade for the Mercedes M178 engine with housing\"\u003e\n\t\u003c\/div\u003e\n    \u003c\/div\u003e\n\n\u003cbr\u003e\u003cbr\u003e\n    \n    \u003cdiv class=\"rflex-container\"\u003e\n    \n      \u003cdiv\u003e\n\u003ciframe loading=\"lazy\" class=\"frame\" src=\"https:\/\/www.youtube.com\/embed\/pJ-pR8PMZlc?rel=0\" title=\"YouTube video player - Weistec W3 Power Package AMG GT S\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen\u003e\u003c\/iframe\u003e\n      \u003c\/div\u003e\n    \n      \u003cdiv\u003e\n        \u003ch3\u003eAMG GT, GTS, GTR Models\u003c\/h3\u003e\n          \u003cp\u003e\n           The Weistec M178 W.3 Turbo Upgrade unlocks the true potential of the 4.0L Biturbo engine.
