Stage 1 Billet TD04 14T Turbocharger Upgrade

The Vargas Turbo Stage 1 Turbo Upgrade utilizes a billet TD04 14T compressor wheel and a machined compressor housing to optimize performance while retaining the stock turbine wheel for quick throttle and lag response. Designed for the N54 engine, this upgrade offers a more efficient alternative to stock turbos, reducing heat and strain under increased boost. Each unit includes upgraded wastegate arms with stainless steel bushings, a 12.6mm flapper assembly, and a 30% larger thrust bearing for improved longevity. This upgrade is compatible with 2007-2010 335i, 2011-2013 335is, and 2007-2010 335xi models (E90/E92/E93 chassis). Please note that this product is not compatible with RHD models or vehicles intended for public highway use. Proper tuning and additional hardware are required to achieve advertised performance goals. As these turbos are built to order, please allow 1-3 weeks for processing. If selecting the rebuilt option, a core charge applies, and used cores must be returned within 30 days. Installation of this performance product may require professional tuning to ensure system reliability.
