Product Description
BorgWarner 179478 S500SX-E Exhaust Housing — 110mm, 1.15 A/R, T6
The BorgWarner 179478 S500SX-E turbine housing uses a T6 twin-flow (divided) volute with a 1.15 A/R for strong mid-to-top-end flow on big-power diesel builds. It’s a direct fit for S500SX / S500SX-E frame turbos using a T6 divided manifold and a 110 mm turbine wheel.
Fitment & Build Notes
- Turbo Series / Frame: S500SX / S500SX-E
- Inlet Flange: T6 divided (twin volute) — requires matching T6 divided manifold
- Turbine Wheel: 110 mm (outer diameter)
- A/R Ratio: 1.15
- Inlet centerline (A): ~3.62" (≈92 mm)
- Not a bolt-on for stock manifolds; verify downpipe and wastegate routing in custom/compound setups

FAQ
Will this housing bolt to a stock manifold?No. It uses a T6 divided inlet and requires a matching T6 divided manifold or adapter.
How does 1.15 A/R behave vs 1.30 or 1.45?
1.15 A/R generally spools quicker than larger A/R housings while still offering strong top-end flow for high-fuel builds and compounds.
Is it compatible with both S500SX and S500SX-E?
Yes—this turbine housing is used across S500SX and S500SX-E frames when matched to the 110 mm turbine wheel and T6 divided manifold.
Do I need to change the downpipe?
Most S500 installations require custom downpipe and wastegate plumbing; verify fitment for your chassis and compound layout.
