The Mercedes 350 CDI is already a strong and capable platform from the factory, but with the right hardware and calibration, it can deliver an entirely new level of performance.
Using our OM642 ball bearing Turbo Upgrade:

and running a great tune from NRP-Performance, this project achieved an impressive 329 HP and 727 Nm of torque.
In addition to the custom ECU calibration, the vehicle was equipped with:
- Big custom intercooler,
- DPF delete.
The result is a significantly more responsive and powerful OM642 setup, with improved spool characteristics thanks to the ball bearing hybrid turbo.
We are delighted to have been a part of this build. Take a look at the dyno graph, and if you’re looking to unlock the full potential of your Mercedes 350 CDI, make sure to check out our turbo upgrade.
