In this episode, the real work begins. After dropping the entire drivetrain out from underneath the BMW 335i in Part 1, it’s time to strip down the original metal-filled N54 engine and begin transferring reusable components onto the replacement engine. The transmission is separated from the engine, the turbos and wiring harness are removed, components are cleaned and organized, and the replacement N54 slowly starts coming back together piece by piece. This series documents what it actually takes to replace a BMW engine the right way, including the setbacks, specialty tools, and massive amount of labor involved behind the scenes.
