Agency Power has continued the horsepower possibilities with this all new twin turbo upgrade for the BMW 135I N54 engine. 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. Purchasing this requires sending in your stock turbos that are in good working order.
To maximize the power, you will need additional power parts to take advantage of what these turbos can do. We highly recommend the following items: Agency Power Downpipes, Agency Power Midpipes, Agency Power Muffler, Agency Power Intercooler, Intake System, Upgraded Fuel Components.
This upgrade will fit: 135i, 335i, 535i
Please discuss this turbo upgrade with a Performance Specialist to ensure your vehicle is setup properly.
