Look no further. The VTT S58 GC Series turbochargers deliver massive power potential while keeping factory spool characteristics and OE fitment. We keep what BMW got right, then remove every limitation we identified: restrictive inlets, inefficient bearing housing oiling structure, weak thrust assembly, and everything else bottlenecking S58 power output. We then apply proprietary VTT revisions and cast our housings at OEM-level quality.
