TTE740+ – Upgrade Turbos – BMW M2 CS / M3 / M4 S55 B30

Description

The TTE740+ is TheTurboEngineers' ultimate hybrid turbo upgrade for the BMW M2 CS, M3, and M4 with the S55 B30 engine. This Stageupgrade is designed to deliver more than 760 hp Delivering exceptional responsiveness and perfect plug-and-play fitment. Based on the original Mitsubishi bi-turbo system, but completely revised for maximum flow and efficiency.

The TTE740+ retains the original turbochargers and actuators, but everything internally has been redesigned. At its heart is a 7+7 billet-milled compressor wheel (50.5mm inlet) combined with a 9-blade high-flow turbine. This combination delivers massive airflow, lower exhaust gas temperatures, and faster spooling. Furthermore, the bearings have been reinforced for both axial and radial loads, ensuring long-term reliability at high boost pressures.

When purchasing new turbos, two larger intakes are included—one CNC-machined aluminum intake pipe and one custom OEM plastic intake. This provides an immediate improvement in airflow and performance. Each turbo is individually balanced using high-speed VSR technology up to 250,000 rpm and comes with an official balance report.
