BNR offers 2 options for the Focus ST!   First option is the BNR2867 Generation 2 and the second option is the BNR3071 Generation 2.  Both units use our own cast iron adapters that bolt to our GT series internal wastegate turbine housing which makes it simply bolt directly to the Focus ST!  This is set up to mount all OEM external hardware (water/oil lines/bolts ect.) with ease!  Don’t have to worry about leaky aftermarket fittings, just use all that high end, stainless fittings and hardware that comes with the car!  All boost control fittings from the stock turbo transfer right over to our custom T04B compressor housing and cast aluminum 3″ compressor inlet!  If you have a 3″ intake system on the car all you will need is a 3″ silicone coupler to fit it up to your aftermarket intake system!  Using either upgrade will require you to run and external bypass/blow off valve.  We supply all the hardware needed to install the turbocharger (must reuse original header gasket).

FOST BNR2867

The 2867G2 compressor option is really the best option for stock fuel system and stock block cars.  It has enough air flow for 400-420 WHP with really good response and power band.  From what I gather the stock fuel system is only good for 350 WHP before auxiliary fueling is needed.  If you don’t have plans for aux fuel or built engine, this turbo is your guy.

FOST BNR3071

The 3071 G2 is intended for cars with built engines and auxiliary fuel systems!  This turbo is good for up to around 500 WHP.   This upgrade takes a little longer to spool over the 2867 but nets around 100 more peak HP.  If you anticipate aux fuel system and/or a forged internal engine this turbo would be the best option!
