The most popular turbo upgrade for the Mazdaspeed/MPS platform hands down!
The BNR S3 version 2 turbocharger has a 2.36” inlet and works with almost 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!
