CTS-TR-0300RS Bi-Turbo System for BMW N54 E9x 3 Series

Looking to unleash serious performance from your N54-powered 3 Series without moving to a single turbo conversion? This CTS Turbo RS Stage 2+ twin-turbocharger set is a brand-new, stock-location solution designed for huge airflow, quick response and repeatable results. With the correct supporting hardware and professional calibration, this pair is capable of around 600 to 700 bhp while retaining OEM-style packaging and drivability. No core exchange and no waiting time.

We have fitted and road-tested these units at MJ Modifications and our customers love the transformation. Strong mid-range punch, excellent top-end pull and a precise fit make this an outstanding choice for fast road and track builds on the N54 platform.
