The Mosselman MSL50-65 Stage 2 Turbocharger Kit is the proven BMW N54 turbo upgrade for drivers who want serious performance, fast spool and OEM reliability.

We have installed these Mosselman N54 Stage 2 turbos on customer cars and our own builds, and the feedback has been superb: low-lag response, a wide powerband and excellent reliability when paired with the right supporting hardware and a quality ECU remap. If you are searching for a BMW N54 turbo upgrade, 135i turbo upgrade, 335i turbo upgrade or Z4 35i turbo upgrade, this is the kit enthusiasts ask for.
