BorgWarner AirWerks S400 SXE 11096 aka S488SX-E
Utilizing the latest generation 87.93mm billet EFR compressor wheel aerodynamics with uprated 360 degree thrust assemblies, the all new ‘SX-Enhanced’ turbos redefine performance and value for modern turbochargers.
This proven design is packaged in a purpose built SX-E compressor housing with ported-shroud inlet and speed sensor port. It is paired with traditional Airwerks 96mm Inconel Turbine and Flexible Housing options. The brand new 87.93mm S400SX-E Turbocharger from Borg Warner is the 3rd largest T6 turbo in the Airwerks lineup. Ideal for applications which require more airflow than the Garrett GTX45R or 76mm S400SX, but also want better fitment than most T6 turbos. Higher airflow rates make this an excellent match for high-boost and high-power 88mm drag racing applications. Thermals are taken care of by an Oil-Cooled Journal Bearing only.

Airwerks® Series Turbochargers
Simple. Scalable. Strong.
Airwerks turbochargers are designed for the competitive motorsports market as well as drivers retrofitting a naturally aspirated engine or looking for a little more performance from a factory turbocharged car.
Engineered specifically for drag racing, pulling, and road racing, AirWerks turbochargers have earned a reputation as robust, brute-force induction systems. Looking for a no-frills replacement? Want to upgrade your turbocharger? Working with limited space? BorgWarner’s AirWerks turbochargers are the perfect go-to product for many applications.
With a twin hydrodynamic journal bearing design, AirWerks turbochargers feature an effective high-pressure ratio compressor stage, extended-tip technology and a high-efficiency turbine stage. The configuration provides ultra-fast response and more than 70 PSI of boost.
- 3AN oil feed line is recommended. If -4AN or larger is used, an oil restrictor is required (just like GT turbos)
- This turbo uses a T6 Divided footprint, with 5.75″ Marmon Downpipe connection
- This turbo features an extended tip compressor wheel for increased high boost performance and map width.

- Max warm oil pressure: 5 bar (73.5psi)
- Max cold oil pressure: 8 bar (118psi)
- When starting a fresh engine build or in extremely cold climates – oil pressure must reach 0.5bar (7.2psi) within 4 seconds maximum.
- Do not load the engine with full boost and WOT until full operating oil pressure is present
- Do not load the engine with full boost and WOT if any boost leaks are present (this can result in turbocharger overspeed)
