SteamSpeed STX 67 BMW N55 Turbocharger Upgrade

 The Steam STX 67 for BMW N55 is a direct replacement stock-location turbo for BMW owers with BMW's new TwinPower (twin scroll) 3.0 l inline 6 direct injection motors (BMW engine code N55).  The N55 is motor is used extensively throughout the BMW lineup, but includes: M135i (E82/E88/F20),  335i (E90/E92/F30), etc.

The Steam STX 67 for BWM TwinPower N55 engines provides:

• Turnkey stock location replacement of the OEM turbo.  This means your turbo will appear stock, and can utilize exhaust, intercoolers, and intakes designed for the stock turbo.


• Made from all brand new components, so there are no core deposits, and you don't have to return your factory turbo.  The turbo is brand new instead of a rebuilt used OEM turbo.


• The STX 67 compressor wheel is 5-axis CNC milled billet aluminum and flows ~25-30% more than the stock turbo.


• +75-90 HP at the wheels over stock

Turbine wheel: 47mm / 53mm

Compressor wheel options: 45.8mm / 67mm

This upgrade is designed for stock fitment and replaces the center cartridge and compressor housing, so it will reuse the stock turbine housing, actuator, and blow off valve. Our CHRA and compressor housing fit directly into your stock turbine housing, intake, and intercooler..
