*Newest version 3 NOW AVAILABLE and shown in pictures. The V3 now comes with the machined compressor wheel with better aerodynamics.

BNR Supercars has several bolt on turbo upgrade options for the Mazdaspeed 3, Mazdaspeed 6, and the Mazda CX7.  These turbo upgrades are designed to be a bolt on 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 newly designed replacement/upgrade far overshadows the K04 turbocharger that comes equipped on the Mazdaspeeds.

The benefit of the BNR turbo upgrade for the Mazdaspeed 3, Mazdaspeed 6, and Mazda CX7 is the increased shaft size, shorter shaft length, bigger bearings, better thrust bearing assembly, better turbine wheel, more efficient compressor wheel, and last but not least, more reliability.  No question this turbo upgrade is far more superior to the original equipment turbocharger on the Mazdaspeed MZR DISI.

Bolt on! You read that right, it says bolt on. The BNR is a bigger that stock turbo though it still fits within the factory K04 frame and is therefore one of the easiest turbo upgrades to install. This Mazdaspeed turbo upgrade is for the customer wanting to reach the limitations of the stock engine without killing turbo response! 

The BNR S3 Turbo upgrade for the Mazdaspeed 3, Mazdaspeed 6, and Mazda CX7 includes the following:

  • BNR GT28 non ball bearing CHRA
  • 360 degree thrust assembly
  • Upgraded wastegate actuator assembly set at 14 psi
  • Balanced to or under .5 gram/in2
  • Upgraded BNR compressor housing with custom outlet for direct fitment
  • BNR's new turbine housing with improved wastegate port and valve assembly(also made thicker to help prevent cracking)
  • Blue printed in house
  • 1 year warranty!

    MY LUCK

    I don’t know if all are like this, but after 200 miles after install, no heavy boosting just casual driving to work, my turbo had excessive shaft play and rattled under boost. Hopefully they warranty it.

    If you want a stronger turbo this will get you there

    Almost everything you’ll need. 3.0 -3.5 map sensor and harness needed, I went with grimmspeed boost . This is part of a engine swap to replace my blown engine. I’m not going stock I’m going stronger the. Before. I’m adding this plus Manley H and I plan on destroying most compatition with ny speed 3

    Perfect

    Cant fault the turbo or kit, everything you need (apart from instructions!) come with it. No complaints, the turbo has a smooth power delivery and its much quieter than the stock K04. I coupled this with a Grimspeed boost controller and the combination is perfect for my goals.
