Product Description

The BorgWarner 14961019007 Turbine Housing is a high-performance replacement exhaust housing engineered for S400SX series turbochargers equipped with 96mm turbine wheels, supporting extreme horsepower applications from 550 HP to over 1,200 HP in single turbo configurations. Featuring a 1.15 A/R ratio with twin scroll divided volute design, this housing optimizes exhaust pulse separation through the T6 divided inlet for improved turbine response and quicker spool-up compared to undivided configurations. The cast iron construction withstands extreme exhaust gas temperatures found in high-boost gasoline and diesel performance engines, while the external wastegate provision allows precise boost control with your choice of aftermarket wastegate. The 5.75" full Marmon V-band outlet provides a secure, leak-free connection to your downpipe or exhaust system. This housing is ideal for upgrading existing S400SX, S400SX-E, S400SX4, S410SX, and S47X series turbochargers to a different A/R ratio for optimized power delivery, or as a direct replacement for worn components. Manufactured in BorgWarner's Arden, North Carolina facility and backed by their 1-year limited warranty.
