BorgWarner | AirWerks S300 Turbine Housing

AirWerks S300 Turbine Housing — A/R 0.91

Upgrade or complete your BorgWarner AirWerks S300 turbocharger build with the 177208 turbine housing. Cast from durable iron and engineered to OEM tolerances, this housing pairs with BorgWarner S300 series 80/74mm turbine wheels to deliver consistent spool-up, optimized exhaust flow, and reliable boost response on performance gasoline and diesel applications.

With an A/R of 0.91 and a single scroll configuration, this housing is sized to balance low-end response with top-end flow — ideal for street, strip, and dedicated motorsport builds where exhaust energy management matters.
