TiAL Sport 007316 BWVB3745 1.30 A/R EFR 80mm Stainless Steel Turbine Housing

The TiAL Sport 007316 (BWVB3745) is an investment-cast stainless steel turbine housing designed for the BorgWarner EFR 8374 (80mm) turbocharger platform. Featuring a 1.30 A/R ratio and V-band inlet and outlet connections, this housing is purpose-built for high-flow, high-horsepower turbo applications where strength, heat resistance, and precise exhaust flow management are critical.

Key Features:

• Investment-cast stainless steel construction — lightweight, high-strength alternative to sand-cast housings with superior heat and corrosion resistance
• 1.30 A/R ratio — optimized for high-RPM, high-flow applications demanding maximum top-end power potential
• V-band inlet and outlet (BWVB3745 designation) — simplifies installation, improves sealing, and allows rotational adjustment during fitment
• Designed specifically for the BorgWarner EFR 80mm turbine wheel (EFR 8374 frame)
• Manufactured in the USA using TiAL Sport's on-site foundry and CNC machining capabilities
• Compatible with TiAL Sport's external wastegate provisions for precision boost control integration

TiAL Sport turbine housings are engineered and produced entirely in-house, leveraging an exclusive on-site foundry to ensure dimensional accuracy and material consistency across every unit. This housing is an ideal choice for motorsport builds and high-performance street applications requiring a reliable, proven turbine housing on the EFR platform.
