BorgWarner Turbocharger EFR B1 7163G 0.80 a/r VTF WG

If you're building a high-performance engine and looking to significantly increase power output, a robust turbocharger like the BorgWarner EFR B1 7163G is a critical component. This turbocharger is designed to handle substantial airflow and boost pressures, making it suitable for serious engine builds where maximizing performance is the goal. It features a 71mm compressor wheel and a 63mm turbine wheel, offering a good balance between airflow capacity and responsiveness for many applications.

The EFR B1 series turbos are known for their advanced features, including a ceramic ball bearing system. This system helps reduce friction and improve spool-up time compared to traditional journal bearing turbos, meaning you get boost pressure faster. The turbine housing is cast from a high-temperature alloy and features a 0.80 A/R (Area/Radius) ratio, which is optimized for a broad powerband, providing strong performance across a wide range of engine speeds. The integrated wastegate (VTF WG) helps regulate boost pressure precisely, ensuring consistent power delivery and protecting your engine from over-boosting.

This turbocharger is a well-built unit from BorgWarner, a trusted name in forced induction. It's important to note that this turbocharger is not CARB approved and cannot be shipped to California. Proper supporting modifications, such as an upgraded fuel system, engine management tuning, and appropriate exhaust and intake plumbing, are essential for optimal performance and reliability when installing a turbocharger of this caliber.
