BNR S2 Turbo Kit Mazdaspeed 3 2007-2013 | Mazdaspeed 6 2006-2007

The S2 has the same inlet diameter as stock (2.25”).   Only things you will need to modify is relocation of the boost control solinoid. 

It’s a direct bolt in capable of 40 lbs/min of air flow.  The benefit with the S2 over the S1 is added response and mid range from the larger A/R ratio of the compressor housing and an upgraded wastegate actuator.  Peak power stays the same.  This is what you get when you order an S2!
