BNR S6

BNR’s largest turbocharger is available for purchase for the Speeds!  The S6 has a 3.5” compressor inlet and works with a 3.5” or larger intake pipe (same casting as S4/5).   All the tuners like using an aftermarket boost control going to your 44-46mm v band style wastegate!  The S6’s point milled, billet compressor wheel is rated for 75 lb/min air flow and is the larger of the 76mm Garrett compressor wheels with a 58mm inducer and 76mm exducer with a 3mm compressor tip height extension.  Our S6  comes with a .82 a/r turbine housing with 44mm external wastegate flange!  This turbocharger on a forged engine with ported stock intake gets 20 psi by 3600-3700 RPM.   Auxilary port injection is needed to go higher than stock fuel limitation  (370 WHP).  The S6 has the capabilities for 650+ WHP!!!     We lowered the price recently because we stopped making the oil return lines!  (OIL LINE DETAILS HERE)

BNR Supercars specializes in the Mazdaspeed3 and Mazdaspeed6 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.

Good product and a good price
Size: 26"+24"+14"
Fit like a charm and at a great price. The connection points are tight on the wiper arms and the rubber seems to be good quality. Time will tell once these are used for a while to see how they hold up.

Great Price and perfect fit!
Size: 26"+18"+16
Here is a simple solution to replacing your wipers. It your vehicle sits out in the weather, they need to be replaced a couple of times every year or you will be like the guy driving down the highway at 30 MPH in a downpour because they can't see the road. Forget the frustration of trying to look up your wipers in the store that doesn't have the up to date book and get all three wipers for your car here. Also they are a perfect fit and delivered to your home. You will have to install them.
