About B58 turbos & boost

A turbo upgrade is the step after a full bolt-on, fuel and ethanol build. Hybrid turbos keep the factory fitment and most of the stock spool; big singles trade response for top-end power.

Turbos are generation- and head-specific: a Gen 2 "2-port" turbo won't bolt to a 6-port engine, and every upgrade needs a custom tune and a fuel system to match. Downpipes have their own page now: B58 downpipes.
