S300A113 for Mack E7: The Classic Mack Turbo
The Mack E7 12.0L was the workhorse of the Mack truck lineup for decades. The S300A113 is the stock BorgWarner turbo for the IEGR-era E7 (2002-2007). When the E7 was replaced by the MP7 and MP8 (based on Volvo D13 architecture), Mack moved to Holset HE400VG/HE451VE turbos.
