The BNR S4 is the most popular turbocharger in the MZR market! The S4 will max out the original engine and has enough on the table to make mid 500 WHP with Auxiliary fueling in internal wastegated orientation. Great response and amazing sounds come from this unit! Makes a great entry level turbocharger for built engines.
