The BL62X is a stock-location hybrid turbocharger for first-generation BMW B58 engines (B58B30M0) with the 6-port turbine housing. It is rated at 800HP and built for street and mild track cars that have taken the factory turbo as far as it will go and want a real power step without moving to a big-single kit. The OEM Gen 1 6-port turbine housing and electronic wastegate are retained, so there is no custom manifold, no relocated downpipe flange, and no new oil or coolant lines.

It does not fit B58 Gen 2 (6-port or 2-port) or B48/B46 engines, so confirm engine code B58B30M0 before ordering. A custom tune is required, and fueling, charge pipe, and downpipe should be planned around the power target.
