S2 Turbo upgrade 2007-2013 Mazdaspeed 3, Mazdaspeed 6 and CX7, MPS 3, MPS 6

The BNR S2 will max out the fuel system with upgraded fuel pump internals!  It really competes with the S3 but has right at a 370 WHP limitation on flow.  By far the most overlooked turbo in our product range!  This unit out responds the S1 and provides more under the curve performance over the S1 because of the cooler charge air from the upgraded compressor housing!  This little guy packs a great punch and spools like the stock K04!  We do suggest a tune with this unit because out of the box they have the heavy duty wastegate set at 15 psi!
