Product Description
BORGWARNER 178855 S400SX (S467/83) — 1.10 A/R, T4 Divided Housing
Meet the proven AirWerks workhorse for big single builds and atmospheric roles in compounds. The 178855 pairs a ~67.7 mm compressor with an 83/74 mm turbine and a 1.10 A/R T4 twin-scroll housing for stout flow, rugged journal-bearing reliability, and adjustable housing orientation. Ideal where you need serious air without sacrificing durability.
Why this S467/83 works
- Extended-Tip compressor tech for strong mid/top-end pull.
- Twin hydrodynamic journal bearings for durability under heat and load.
- T4 divided turbine housing to improve pulse energy and spool characteristics.
- Standardized inlet/outlet connections and recirculation grooves to ease plumbing.
Fitment & Setup Notes
- Universal performance turbo—not vehicle-specific. Requires a T4 divided manifold, appropriate downpipe, oil feed/−10AN to −12AN drain, and charge-pipe transitions.
- Common use cases: big single or low-pressure (atmospheric) charger in compound sets.
- Verify compressor inlet/outlet and turbine outlet sizes for your specific build before purchase.
