Fitment & Notes

- Inlet flange: T6 divided (twin-scroll)
- Outlet: Standard S400 marmon discharge (match to your downpipe)
- Typical pairings: S464 / S467 / S472 compressor builds; ideal as low-pressure (atmospheric) in S300/S400 compounds
- Spool characteristics: Later than smaller A/Rs; rewards with reduced drive pressure and stronger high-RPM power

FAQ
Will this housing fit any S400?
It’s designed for BorgWarner S400/SX frames using an 83mm turbine wheel and a T6 divided inlet. Verify turbine wheel size, inlet flange, and outlet style before ordering.
How does 1.10 A/R affect performance?
A 1.10 A/R favors higher-RPM flow and lower drive pressure versus smaller A/Rs, at the cost of later spool. It’s popular for big singles and atmospheric compound setups.
What turbo builds commonly use 176811?
S464/S467/S472-based S400 singles and S300/S400 compound systems where the S400 serves as the low-pressure unit.
Is this a genuine BorgWarner part?
Yes—CPP Diesel supplies authentic BorgWarner AirWerks components.
