We are very excited to announce our partnership with BNR Supercars products. This allows us to offer you turbos packaged with tunes resulting in big savings for your big turbo projects! 
This package includes the BNR bolt-on turbo kit featuring the BNR S3 GT2871 turbo as well as a Stratified Full Custom tuneThe included tune is a single map tune for the fuel of your choice (91, 93, OR E85 blend), adding a second fuel map costs an additional $50.  
Big Turbo Prerequisites: 
1. The OEM 2 port EBCS cannot handle the needs of a bigger turbo. To properly control boost you will need a Three Port EBCV. We do not recommend running any mechanical boost controllers such as a manual boost controller. 
2. An upgraded BPV is neccessary to run a bigger turbo. The OEM BPV will crack open when surpassing 21 psi of boost pressure causing a loss in airflow and performance. This Article highlights the shortcomings of the OEM BPV. Contact Us if you'd like to include a BPV in your turbo order. 
3. A 3" or larger intake. OEM-sized intakes work well for the OEM MazdaSpeed turbocharger, however, they are inadequite for bigger turbos. Recommended is an intake with at least a 3" ID (Contact Us if you'd like to include an intake in your turbo order).
4. A 3 Bar MAP sensor. The OEM MAP sensor is only accurate to around 21 psi of boost. When tuning a big turbo we will surpass this figure so the 3 bar map sensor becomes necessary. BitWise makes a plug and play harness which makes this a very easy swap.
5. With great power comes great responsibility, protect your motor with a Stratified Guardian Angel. Although this is not neccessary to run a big turbo it is very wise to protect your investmet with the Stratified Guardian Angel. Over the years the GA has saved countless motors from dangerous overboost conditions.
