Thread: BNR S3's In Stock at EdgeAutosport!

  1. Default BNR S3's In Stock at EdgeAutosport!






    By now, everyone has heard of the BNR turbo upgrade for the Mazdaspeed 3 and 6. It is a lower cost turbo upgrade that offers a pretty decent bang for the buck. $1099 gets you a nice boost in performance and offers a great replacement for the stock K04.








    The benefit of the BNR upgrade is the increased shaft size, shorter shaft, bigger bearings, better thrust bearing assembly, better turbine wheel, and more efficient compressor wheel. These things combine to make for a much more reliable turbo. No question this upgrade is far more superior to the original equipment turbocharger on the Mazdas.










    One of the most appealing aspects of the BNR turbo is the stock turbo like response with the added top end performance. It will change the way your Mazdaspeed drives, but only for the better!

    Can't wait to get our hands on the new BNR S4. Just had a local make 397whp with an e85 mix on this turbo.

    From stock, to GT3071, to substantially less modded, many lessons learned!

    With the proper tune, the S3 and S4 will be fine on stock engine.
