Product Details

BorgWarner is well-known for their high-performance turbochargers, and the EFR B2 7670 is a prime example of their engineering. This turbocharger is built for serious performance applications, offering a robust solution for those looking to significantly increase their vehicle's power output. It features a 76mm compressor wheel and a 70mm turbine wheel, designed to provide a broad powerband with quick spool times for its size.

The EFR B2 7670 comes with a 0.83 A/R (Area/Radius) turbine housing, which is a V-band outlet type. This specific housing size is a good balance, allowing for strong top-end power while still maintaining reasonable boost response. The integrated wastegate helps regulate boost pressure, ensuring consistent performance and protecting your engine. The turbine housing is constructed from durable cast iron, built to withstand the high temperatures and pressures associated with turbocharging.

This turbocharger is a popular choice for enthusiasts looking to upgrade their forced induction system. It's designed for custom builds where precise control and significant power gains are desired. While this unit is not CARB approved and cannot be shipped to California, it represents a solid option for performance builds elsewhere. For installation, it's recommended to consult with a professional or refer to detailed build guides, as turbocharger installations often require custom fabrication for exhaust, intake, and oil/coolant lines.
