In this video, I provide a comprehensive breakdown of the costs associated with building a 500+ horsepower BMW 330i, powered by the reliable B48 4-cylinder engine. From the upgraded turbo and intake manifold to ECU tuning and supporting modifications, I’ll cover every expense and detail that went into achieving this power level.
This build prioritizes reliability without sacrificing performance, making it suitable for daily driving while delivering impressive numbers on the dyno. I’ll also discuss how the upgrades integrate with the G20 chassis, including considerations for cooling, fueling, and drivetrain compatibility. Whether you're planning your own high-performance build or want an in-depth look at what it takes to extract this level of power from a B48, this video offers detailed insights into the process and costs.
