Turbine Housings
Turbine Housings & Turbo Exhaust Housings
The turbine housing directs exhaust gas onto the turbine wheel, spinning the turbocharger. Turbine housing size, A/R ratio, and inlet flange type directly control spool speed, backpressure, and power delivery, making the right housing choice critical for matching the turbo to the engine’s power band and intended use.
OneFastShop carries turbine housings including T3, T4, V-band, and twin-scroll inlet flanges, a wide range of A/R ratios, internal and external wastegate configurations, and turbine housings sized for popular turbo frame sizes and applications.
Every turbine housing at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're swapping housings to change spool characteristics, building a custom turbo setup, or replacing a cracked housing, OneFastShop has the turbine housing.
