BNR offers 2 Turbo options for the Focus ST!

The first option is the BNR ST67 (2867 Gen2) and the second option is the BNR ST71 (3071 Gen2).  Both units use our own cast iron adapters that bolt to our GT series internal wastegate turbine housing which makes it fit in the factory turbocharger location!

The BNR ST71 turbocharger upgrade is intended for cars with auxiliary fuel systems!  This turbo is good for up to around 500 WHP.   This upgrade takes a little longer to spool over the ST67 (300 RPM) but nets around 100 more peak HP when maxed out.  If you anticipate aux fuel system and/or a forged internal engine this turbo would be the best option!

This is what you get when you purchase the ST71!

Note from BNR:

A Catch can is highly suggested to keep the crankcase ventilation happy in your engine.  The more boost you run the more your crankcase wants to pressurize.  That pressure doesn’t allow the turbo to drain its oil efficiently.  When the oil backs up in the turbo, the oil level rises above the turbine, and the compressor seals in the turbocharger causing oil to enter the compressor housing or turbine housing causing smoking/leaking.     Some cars with crankcase ventilation issues will require a restricted banjo bolt to keep the oil level down in the turbocharger.  Please see Damond Motorsports Catch Can options here:

*Please note, that turbos may ship directly from BNR, so please allow extra time for the turbo to be built and delivered.
