BNR S3 V5 Turbo Kit Mazdaspeed 3 2007-2013 | Mazdaspeed 6 2006-2007

Its been about 3-4 years with the Version 4 and they've been great performers.  Times change and with the Version 5 we updated compressor wheel aero to the G series so you guys can enjoy even better response and HP output!  

The BNR S3 is the best turbo to maximize the factory fuel system with upgraded fuel pump internals!  This unit has been a red hot seller since 2009 when we started offering upgrades for the MZR platform!  Great tip in response along with the potential to make up to 390 WHP!
