BNR Supercars specializes in the Mazdaspeed 3/6 and MPS turbochargers.
Peak numbers are not what we are into. We like designing turbocharger upgrades that produce maximum under the curve power and torque. It makes these cars much more responsive and fun to drive on the street. When you get greedy and go for that peak number, it kills the bottom and mid-range torque. No bottom end torque makes the engine not as responsive for autocross/road racing and in BNR's opinion not as fun to drive!
These engines are doing very well handling 400-450 WHP with the stock bottom end. Most people looking for a reliable replacement over the stock smoking KO4 usually go for the S1 or S2 turbocharger models since a tune isn’t required. If your car is fully bolted with high performance fuel pump internals we suggest an S3 with a tune. Fully bolted with added methanol injection go with the S4 and a tune. Stock engine internals, don’t even think about doing an S5 or S6!
*Divorced down pipes do not work with BNR turbocharger upgrades! If they are used, the wastegate valves will not open properly causing extreme high boost problems!*
*Built engines need a custom oil supply line for turbocharger protection! Click link for details!*
Mazdaspeed 3/6 Custom Oil supply line “Built engines only”
*S5 and S6 model turbochargers to cover the cost of the custom oil drain line!
*Please note, turbos may ship directly from BNR, so please allow extra time for the turbo to be built and delivered.
