BNR S3 Turbo Kit Mazdaspeed 3 2007-2013 | Mazdaspeed 6 2006-2007

The BNR S3 version 2 turbocharger has a 2.36” inlet and works with most all the aftermarket turbo inlet tubes.   All the tuners like using an aftermarket boost control solenoid with a single barbed wastegate actuator.  The S3’s compressor wheel is rated for 46 lb/min air flow. 

We’ve had countless customers dyno 360-400 WHP with the S3.  The S3 will max the factory fuel system with the upgraded fuel pump internals at 360-370 WHP.  If you don’t plan on axillary methanol injection, the s3 is what you need!  Here is what you get with the S3 turbocharger upgrade!
