A new day and another tuner launches a new product around BMW vehicles. This time, Vivid Racing brings out an turbo upgrade kit to the BMW 135i Coupe. In its standard form, the N54 engine powering the 135i produces 300 horsepower. With the upgrade kit and additional power parts, the N54 engine will be capable of producing 500 horsepower.

Without any further ado, let’s have a look at Vivid Racing’s project.

“Vivid Racing has continued the horsepower possibilities with this all new twin turbo upgrade for the BMW 135I N54 engine. Have spent some time behind the wheel of our Project 135I, we wanted to develop a turbo upgrade that would not take out the stock look, feel, and functionality of the BMW engine.

For someone that wants the next stage in performance once all the support mods are done, this kit by Vivid Racing is it! 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 cost of associated with this turbo upgrade is based off of a core charge. We have turbos available already upgraded or you can send your turbos to be modified.

If you choose to use our core exchange program, you will be billed an additional $3500 for the cost of new turbos. This amount will be refunded to you upon receipt of your original turbos back. 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. We highly recommend the following items: Agency Power Downpipes, Agency Power Midpipes, Agency Power Muffler, Agency Power Intercooler, Injen Intake System, Upgraded Fuel Components.”
