EcoBoost Mustang Turbo Swap Brings Loads Of Power

Sponsored Links

Buying a Ford Mustang and then starting to hop it up with more style and performance is a tradition that has been around as long as the venerable pony car. There are plenty of aftermarket upgrades for performance for both the base EcoBoost Mustang and the Mustang GT with its 5.0L V8 engine. Mustang fans who started with the base 2.3-liter EcoBoost four-cylinder making 310 horsepower and 320 pound-foot of torque and wish they had bought the GT instead can now put an end to that desire.

Turbonetics has a drop-in twin-scroll turbocharger that the company says will replace the stock turbo on an EcoBoost Mustang in about an hour using only hand-tools. The drop-in turbo has a larger 52mm compressor wheel and Inconel turbine side with dual ceramic ball bearings. With the right tune, dyno testing has shown that the new turbo can push up to 520 horsepower. It’s not clear if that is at the wheels or crank, we assume that rating is at the wheels.

If you are wondering, Ford saw fit to build the EcoBoost four-cylinder in the Mustang with a forged crank and connecting rods from the factory, the engine will reportedly stay together, but this will likely void a warranty. The stock EcoBoost runs 20 psi of boost to reach its 310 horsepower rating. The most impressive part is that the larger Turbonetics turbo makes that claimed 520 horsepower with the same 20 psi of boost.

With more power will come more heat, so this upgraded turbo might require an upgraded intercooler as well. The Turbonetics turbo that EcoBoost Mustang owners want is PN 11910 and retails for $2,869. When the company says drop-in, they take that seriously. The oil inlet and outlets are in the same place as the stock turbo, and the kit includes everything you need, including gaskets, O-rings, and couplers. This turbo might be the perfect add-on for the 2.3L High Performance Package buyers looking to run with the Shelby GT350.

    • As a matter of fact, there’s no limit for the amount of extra power you can get out of a turbo. The limitations are set by the rest of the engine builds, tweaks and settings. That and money in your pockets…

  1. Wrong
    We do it all the time…
    As long as the fuel system can handle it (usually requires pump, injectors, or secondary fuel) a larger turbo can support HUGE gains.

    The problem with the ecoORboost is that the stock turbo is tuned for extremely quick spool times, so it falls on its face at high rpm. A turbo swap moves your max torque/power up the rev range a little but can maintain the high cfm/boost at max rpm. There’s where the majority of your gains are, not from more boost (higher psi) but from more airflow through the motor (motor is just an air pump yah know)

    Sorry if the old dinosaur large displacement NA/supercharged engines can’t reliably do it…
    Modern direct injected turbo motors have phenomenal power potential, and can do it reliably.

  2. Ummmmm. How can power rise if both turbo produce the same 20psi? Doesn’t make one bit of sense….

  3. 20 psi peak at like 3k_4.5k…
    Then it falls off until redline…
    Stock turbo can not maintain 20psi above 5kish rpm

  4. Density. 20psi is a measure of pressure seperate from mass. The hotter the charge, the less dense. The larger turbo doesn’t heat the air charge up as much when compressing it, so even though it’s 20 psi, there’s more oxygen per volume.

    As long as you can supply the fuel to match more oxygen, you’ll get more power.
