This product has been discontinued and replaced by MTurbo BMW N54 Stage 3.0 Ball Bearing Turbocharger Upgrade



This M Turbo stage 2.0 turbocharger is the only OEM fitment ball bearing turbo currently available on the market! The ball bearing technology offers transient response which enhances the driver experience, as it doesn't have the turbo lag that is commonly associated with the Journal Bearing turbos that is currently flooding the market.


It also has another advantage, it doesn't rely on oil to lubricate the internals as much, which is one of the most common reason that leads to journal bearing turbo failures, such as oil leak and smoking turbos.


It is the perfect upgrade for your BMW with the N54 twin turbo engines, fits BMW 135i, 335i, 535i and Z4. This stage 2 ball bearing turbocharger is suitable for 450 - 610+ bhp and it is 100% OEM fitment, so a direct replacement for you stock turbos.


Price includes both turbos.


MT billet compressor wheel

Super light forged billet compressor wheel with extended tips technology that helps the turbo to maintain a stock-like but faster spool, and also increases the intake airflow to achieve more gains.


MT upgraded high flow turbine

A fine balance has been achieved on the turbo spool in order to generate maximum airflow. The use of ball bearing technology reduces the chance of oil leaks, which are the most common reason for failure on the N54 journal bearing turbos.



All the high speed balancing is performed using the high-tech German Schenker VSR machine, at well over 130,000 rpm by our VSR engineer.  


Wastegate assembly

The re-designed and upgraded N54 wastegate assembly includes wastegate flapper valve, sleeve, actuator arm and rod connector, to improve the well known N54 turbo wastegate rattle issues on the short-lasting weak OEM assembly.
