VTT B58 GC / GC+ / GC-MID Turbocharger Upgrade

VTT's GC-series turbos are all-new castings that keep the B58's factory turbo packaging while fixing its airflow limits and weak internals. VTT reworked the restrictive inlet, the bearing housing oiling and the small thrust assembly, then added its own changes. Because they are new units, there is no core charge.

What you get

• GC: 54/55 wheel sizes (compressor/turbine), rated up to 600 whp on a stock engine.
• GC-MID (TU only): 54/60 wheels, up to 650 whp.
• GC+: 67/68 wheels, up to 800 whp.
• Reworked internals: a freer-flowing inlet, improved bearing housing oiling and an upgraded thrust assembly.
• Three model types: Gen 1 F/G-series BMW 2020 and older; B58 TU for the 2020 A90 Supra and any 2-port BMW; B58 TU for 2020-and-newer A91 Supra and G-series BMW.

Good to know

• The GC choice is the super core only.
