BorgWarner Turbo EFR B2 7670 1.05 a/r VTF

This is the BorgWarner EFR B2 7670 turbocharger, part number 179392. It's a well-built unit designed for enthusiasts looking to significantly increase their vehicle's power output through forced induction. The EFR (Engineered for Racing) series from BorgWarner is known for its advanced technology and robust construction, making this turbo a solid choice for serious performance builds.

The B2 7670 features a 76mm compressor wheel and a 70mm turbine wheel, offering a good balance for a wide range of engine sizes and applications. The 1.05 A/R (Area/Radius) ratio on the turbine housing helps to improve exhaust gas flow and spool characteristics, aiming for quicker response without sacrificing top-end power. This particular model includes the VTF (Variable Turbine Flange) system, which allows for easier installation by providing a standardized mounting pattern that can adapt to various exhaust manifold setups. The turbo also incorporates features like a dual ceramic ball bearing system for improved durability and faster spool-up compared to traditional journal bearing turbos. Its stainless steel turbine housing is built to withstand high temperatures, contributing to its longevity under demanding conditions.

When considering a turbocharger of this caliber, it's important to ensure your engine and supporting systems are prepared for the increased airflow and boost pressure. This includes proper fuel delivery, engine management tuning, and potentially upgraded intercooling and exhaust components. This turbocharger is not CARB approved and cannot be shipped to California.
