It has been almost two years for The Function Factory, Function Factory Performance, Full-Race Motorsports and Turbonetics / PTE. Through the dark and mist, we have been quietly testing the Turbonetics NX2 drop in turbocharger unit on our 2016 Ford Mustang Ecoboost and have installed over 7 units locally in Arizona.


Before installing the turbo, we made sure to get a baseline on our Mustang. Stock turbo, 91 Octane, full bolt-ons and no tune, we were able to make 310WHP with 312WTQ. Freak of nature? Who knows, but this car did rip on stock turbo.

Here is Chris’ actual Turbonetics NX2 Drop In Turbocharger for his 2017 Ford Mustang Ecoboost.


To start, make sure the car is completely cooled off, if not… I mean you’re more than welcome to find out and comment on this post. Allen begins by removing the stock intake and hot side charge pipe.

Carefully remove the coolant and oil lines from the OEM turbocharger. Do not remove the oil drain from the block, disconnect it from the CHRA / turbocharger. Again, we warn you to make sure the car is cooled, if not, again, please comment on this post to tell us what happened. Disconnect your O2 Sensor from the back of the head. Using needle nose pliers, remove all vacuum lines connected to the turbo. There are two bolts on the back of the turbo, you will need to loosen these to remove either your aftermarket or stock downpipe. 4 bolts hold the turbocharger to the head, 2 on top, 2 on the bottom. If you haven’t had 3rd degree burns yet, remove the 4 nuts and other nuts that hold the heat shield. Keep the heat shield as you will reuse it. The turbo should be completely loose at this point, pull it straight out and run to the nearest stereo to blast your favorite song as we are ready to start reassembly with your new turbo.

Let’s start by prepping the turbo. Install the 2 provided studs into the turbine housing, these will be used to hold your OEM or aftermarket downpipe in place. Remove the OEM turbo gasket on the head. Install the provided Ford OEM gasket, make sure that the 90 degree lip of the gasket is facing outward.  Remove and install the provided OEM Ford O-Rings onto your oil and coolant lines. You are now ready to get this bad boy into your Ecoboost. Install is straightforward, how you removed the OEM turbo is how you install the new unit. Make sure that it is flat against the head, install the head shield over the turbine side and use the new OEM hardware provided. Reconnect the downpipe using the provided Ford OEM downpipe flange, lip side faces the turbine, convex side faces the downpipe.

Connect your O2 sensor and get ready for the final pieces. Install the provided intake adapter followed by your modified or stock intake tube. Attach your OEM or modified charge piping to the turbo and intercooler. From there you are ready to attach all your vacuum lines. Stand back, breathe heavy and get ready for some serious power out of your Ecoboost.

But before we start your car and you did opt for an oil change, take this time to dive under the car and remove your old oil filter and drain plug. After a few minutes of draining your oil, install your brand new OEM oil filter, make sure to put a thin layer of oil on the filter to make removal easy. Tighten your drain plug back up and pour 6 quarts of Motul Oil into fill cap. Open your coolant reservoir and dump a full can of Motul Mocool, later, you will warm the car up to see how much distilled water you will need to add. (BUT NOT YET) Step back and marvel your success. Or if we did your install, smile big cause you’re on camera. Take a Snapchat or do it for the gram at this point.

Before we fire this party up, lets go through a quick checklist of parts.

  • Check oil level
  • Drain plug is tight
  • O2 is reconnected
  • All Vacuum lines are secured
  • Hose clamps are tight
  • Turbine to head nuts are tighten
  • Downpipe nuts are tighten

If all of that checks out, we assume that you have a tuner at this point. If not, you’re able to purchase a custom tune from us below. If you already have a tuner, communicate with them to get a baseline map that uses wastegate pressure, 18PSI. Upload your new tune into your programmer, reset your oil life and now you are read for your first start up.

YOUR MUSTANG WILL SMOKE. That does not mean the world is ending. You will see visible smoke from the turbine and out the exhaust. Do not be alarmed, this is only oil coated residue to prevent rust. Yes, it will smell, stay calm and let it burn off. With a flashlight, check your turbocharger for ANY leaks. Check for engine codes, if all is good, let’s go for a test drive.

Overall, this install will take an experienced tech will take 1 hour and a half, an amateur enthusiast, around 4 and a half hours depending on if you have a lift. Difficultly of the job? Around 5/10, with removal of the actual turbo being the hardest part.

We highly recommend that you purchase a tune from us after installing your new turbocharger. You are safe to drive on a baseline tune but you will not have optimum performance. If you decide to run this turbo un-tuned, we cannot guarantee ANY WARRANTY, PROTECTION OR SAFEGUARD of your Mustangs existence.

If you are looking to make more than 420WHP, you will need E30 or MS109 fuel. We have a vendor that we can recommend that provides a Ready To Run kit. If you are looking to make more than 550WHP, please contact us for other turbo kit options.

*Install, dyno and performance video coming soon.
