BMW 335i F30 2012-2015 N55 MWG Mechanical Wastegate Big Turbo Upgrade by Dinan | New Direct-Fit Performance Turbocharger | Bolt-On Replacement Turbo Kit | High-Flow OEM+ Unit | DINANTRONICS Stage 4 Compatible

Dinan Big Turbo for BMW N55 MWG - serious power, OEM-like manners

Want sharper throttle response, harder mid-range punch and stronger pull to the limiter without sacrificing refinement? This brand new Dinan uprated turbocharger for the N55 mechanical wastegate engine delivers up to 30 percent more compressor flow than the factory unit, so it holds boost where the stock charger tapers off and keeps efficiency high at elevated rpm. It is a direct-fit performance turbo that transforms the way your 3 Series accelerates on road and at track days.

This is not a rebuilt core. It is a completely new assembly with a custom-cast turbine and an upgraded thrust bearing system for durability and long service life. For the advertised gains, pair it with DINANTRONICS Stage 4 calibration and the Dinan intercooler. A high-flow intake and performance exhaust are recommended to support the extra airflow and keep charge temps under control.
