Agency Power and our turbo engineering partners have this billet turbo wheel upgrade for the BMW 35I N54 turbocharged vehicles. This upgrade utilizes the OEM Mitsubishi TD03 turbos which are then modified with a new compressor wheel and a 7 degree turbine clip.  BMW successfully eliminated turbo lag with the design of these turbos, however left alot of room to gain on the mid to top end RPM range.  Where the stock turbos fall flat, this turbo upgrade will have your car pushing Porsche like 0-60 times and 1/4mile times.   

By modifying the compressor and clipping the turbine wheel, we are able to gain as much as 60HP to the crank over the stock turbochargers with supporting mods. The process to modify the turbos requires precision machining and a complete dissasembly to rebuild the turbos.  This means that even the cores are like getting new units.  To maximize the power, you will need additional power parts to take advantage of what these turbos can do.  Performance upgrades such as a turboback exhaust, intake, intercooler, and tuning will help.


  • Requires your turbos to be sent in for modification.
  • Turnaround time is approximately 2 weeks.
  • Billet wheels have about 18% more blade area.
  • Features a taller 6/7 blade design.    


  • Any BMW 35I series chassis with the N54 engine.
