FAPO TD04L 17T Twin Turbo Kit — N54 E90/E92/E93 335i

FAPO didn't cut corners on the internals. The wastegate flapper valves are machined from stainless steel billet with a thickened actuator rod, delivering more consistent boost control and significantly better durability under the sustained high-load conditions that come with tuned N54 builds. Each turbo also undergoes a rigorous three-stage balancing process — component balancing, dynamic balancing, and VSR high-speed spin balancing — resulting in an imbalance of 0.5mg or less. That level of precision means smoother spool-up, less vibration transferred to the drivetrain, and extended bearing life compared to budget units that skip this step entirely.

Fitment covers the 2007–2013 BMW 335i, 335xi, and 335is across all E90, E91, E92, and E93 body styles equipped with the N54B30 3.0L twin-turbo engine. These turbos are not compatible with the 135i, 535i, Z4, X6, or 740i — verify your chassis and engine code before ordering. There is one important installation note: the compressor housing inlet is larger than the OEM unit, so you will need to source a separate 2-inch (55mm) intake hose to properly connect the turbos to your existing intake piping. Factor this into your build plan and budget before install day.

FAPO backs this kit with a one-year warranty against manufacturing defects from the date of purchase, providing reasonable coverage for a performance upgrade at this price point. For N54 owners looking to push well beyond stock power levels while retaining a twin-scroll, plug-and-play-style installation format, the TD04L 17T kit represents a compelling middle ground between OEM replacement and full-custom turbo builds.
