    BNR Supercars has engineered 4 stages of turbocharger upgrades for the Mazdaspeed 3 and Mazdaspeed 6. These upgrades were designed to be a replacement for the K04 factory turbocharger. The stock K04 is a throw away unit that shouldn't be rebuilt. The weak points of the K04 is the long shaft length, small shaft width, and thrust bearing design. BNR's new designed replacement/upgrade far overshadows the K04 turbocharger that comes equipped on the Mazdas.

    The benefit of the BNR upgrade is the increased shaft size, shorter shaft, bigger bearings, better thrust bearing assembly, better turbine wheel, more efficient compressor wheel, and last but not least, more reliable. No question this upgrade is far more superior to the original equipment turbocharger on the Mazdas.

    The BNR stage 2 has the same CHRA as the stage 1, but the compressor housing is upgraded. This housing easily flows 10% more volume as the stock compressor housing. All oil and water lines are bolt up, compressor housing is upgraded and also an upgraded wastegate actuator is fabricated to the turbocharger.

    This is what the upgrade includes:

    • GT2860 compressor wheel
    • CNC machined turbine and compressor housings
    • GT28 CHRA (center housing rotating assembly)
    • High performance thrust assembly
    • Upgraded turbine wheel
    • Upgraded compressor housing
    • 2.25" inlet
    • Aftermarket adjustable wastegate actuator 16-27psi
    • Full set of replacement studs
    • 1 year warranty
