Description

The BNR Supercars S2V2 turbocharger is an upgrade designed for the Mazdaspeed3 and Mazdaspeed6. It features a GT28 turbine wheel and BNR's GT2860 Gen 2 billet compressor wheel, capable of 43 lbs/min of airflow. This turbocharger maintains the stock inlet diameter of 2.25 inches and offers improved response and mid-range performance compared to the S1 model due to a larger A/R ratio compressor housing and an upgraded wastegate actuator set at 14 psi.

BNR Supercars focuses on turbocharger upgrades that maximize under-the-curve power and torque for a more responsive and enjoyable street driving experience. The S2 is presented as a reliable replacement for stock K04 turbos, often not requiring a tune, and is generally capable of handling up to 400-450 WHP on stock engine internals.
