Once received, they are disassembled and fully inspected. The \n\t    compressor cover and center cartridge are then machined to accept our 5-axis CNC-machined impeller wheel. Externally, no changes are made, \n\t    preserving a completely stock appearance. The new impeller wheel supports greater power levels than the factory unit with little to no \n \t    sacrifice in spool or response. The turbochargers are then reassembled with new seals and fully balanced for smooth operation and OEM service \n\t    life. All original oil and coolant lines bolt right up, making for a simple install.\n\t    \u003cbr\u003e\u003cbr\u003e\n\t    If you prefer not to send in your turbos first, a core exchange option is available. With this option, upgraded turbochargers are shipped to \n\t    you up front for a refundable core charge. We refund the core charge once we receive your turbo units and they pass inspection.\n\t\u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv\u003e\n\t\u003cimg loading=\"lazy\" src=\"graphics\/00000001\/5\/7\/570_w.3_1.jpg\" alt=\"side by side comparison between the Weistec W.3 Turbo Upgrade for the McLaren M838T engine and the factory turbo unit\"\u003e\n    \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\" src=\"https:\/\/www.youtube.com\/embed\/kgyA1dgQQuY?enablejsapi=1\u0026amp;version=3\u0026amp;rel=0\u0026amp;controls=1\u0026amp;playerapiid=ytplayer\u0026amp;modestbranding=1\u0026amp;autohide=1;fs=1\u0026amp;\" allowfullscreen=\"\" class=\"frame\" title=\"Weistec Engineering W.3 Turbo Upgrades\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv\u003e\n      \u003ch3\u003eImproved Top End Performance\u003c\/h3\u003e\n      \u003cp\u003e\n        The Weistec W.3 Turbo Upgrade for the McLaren 3.8L Twin turbo vehicles provides vastly improved top-end performance of the M838T Engine.
