    More Power for More Fun. One of the best ways to produce more power out of your EcoBoost Mustang is by upgrading to a larger turbocharger. Custom Performance Engineering (cp-e) makes the upgrade easy with their Precision Gen I Atmosphere Turbo Kit. This kit is designed to not only replace your stock turbo, but it also replaces the exhaust manifold, catted down pipe and intake to get rid of all the factory restrictions. A Precision Atmosphere Turbo Upgrade Kit will have you laying down twin streaks of black rubber everywhere you go.

    Your Choice of Precision Gen I Turbos. This cp-e Precision Atmosphere Turbo Kit with DownScream Down Pipe is available with your choice of five different Precision Gen I Turbochargers that range from 590 to 735 horsepower. Precision's line of Gen I Turbochargers feature their very own CEA® (Competition Engineered Aerodynamics) compressor wheel. The CEA® compressor wheel is precision machined from a 2618-aluminum forgings to provide higher efficiency and faster transient response for maximum power and performance. The choice is yours - Please select from the options listed above.
    • 505-5558 - 55mm Precision Gen I Turbo rated at 590 Horsepower
    • 505-5858 - 58mm Precision Gen I Turbo rated at 620 Horsepower
    • 505-5862 - 58mm Precision Gen I Turbo rated at 640 Horsepower
    • 505-6262 - 62mm Precision Gen I Turbo rated at 705 Horsepower
    • 505-6266 - 62mm Precision Gen I Turbo rated at 735 Horsepower

    DownScream Down Pipe. Designed to vent the external waste-gate exhaust directly to the atmosphere, this cp-e DownScream Down Pipe will produce a loud aggressive sound that you will absolutely love. This off-road Down Pipe is manufactured in the USA from high quality 3" diameter T-304 stainless steel tubing for superior strength and enduring corrosion resistance. cp-e then completes their Down Pipe in their own Titan™ Uniform Satin Finish to further enhance its strength and appearance.

    High Flow Exhaust Manifold. cp-e engineered their exhaust manifold for the most efficient exhaust flow possible. Cast from 304 stainless steel for durability and strength, this exhaust manifold features extra O2 and EGT bung fittings allowing for the addition of additional sensors. The manifold is protected by a fully encompassing heat shield that holds the heat in the manifold and out of the engine bay to keep under hood temperatures down.

    Upgradable Modular Design. The included exhaust manifold was specifically designed with flanges that fit the Precision V-Band Turbo Housings as well as a Tial MVR External Wastegate. The use of V-Bands makes this kit modular, so that you can upgrade your Turbo as money and time allow. Start with the smaller 5558 unit now and then easily swap it out for the much larger 6766 turbo later. The rest of the kit stays in place, you only need to replace the turbo itself to make more power. This set up is ideal for those performance enthusiast who need to quickly change turbos based on track or racing requirements.

    Calibration Required. Installation of this cp-e Precision Gen I Atmosphere Turbo Upgrade Kit will require the use of a Handheld Tuner to reprogram the vehicles computer (ECU) for operation. By reprogramming your Mustangs ECU you will be able to realize the full power potential that this Turbocharger upgrade has to offer.

    Not CARB Certified. This Turbocharger is not CARB certified at this time, therefore it is not legal for use in California or other states adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

    Application. This cp-e Precision Gen I Atmosphere Turbo Kit with DownScream Down Pipe is specifically designed for use on 2015 to 2018 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-cylinder engine.

    Please Note. An External Wastegate is not included with this CP-E Turbo Kit.

    I know that these kits are meant to be for track use but which one of these kits would be good for a daily driver I would love to add all this horsepower for just a dd but not push my car to its limits everyday. And would I need to upgrade and thing else to support this mod.?

    • The cp-e Precision Gen I Atmosphere Turbo Kit w/ DownScream Pipe would require some supporting modifications, depending on how much power you are seeking to produce. Some of these modifications include an intercooler, fuel system, clutch, cooling system, etc. This kit is capable of yielding a lot of power, however, depending on how much power you are looking to produce and the components required to produce and support that amount of power would vary from application to application. As long as the supporting modifications for the power yield of your motor is sufficient and the vehicle is tuned accordingly, your Mustang should still be suitable daily driver.

    How much horsepower does one get with 590hr turbo kit without upgrading anything else? Is it close to 500hp? My car is a daily driver and I would like to get that extra power when need be.

    • The cp-e Precision Gen I Atmosphere Turbo Kit with the 590 HP option will produce roughly 590 HP with the proper tune and supporting mods. Without the supporting mods, the car will see a bit less horsepower gain depending on what tune you are running.

    I am thinking of getting a turbo upgrade and only going for about 450hp and 450 torque with my ecoboost mustang. I already have the mishimoto hot and cold piping, intercooler, and full catback exhaust, CAI, catch can, new spark plugs, throttle body spacer. What else would I need to support 450 hp? I have been doing a lot of research on this and was looking at the 5862 turbo. I guess i just want to know what other mods would i need to support that turbo upgrade.

    • Some supporting mods I would recommend would be, fuel system, clutch, cooling system, etc. This kit is capable of yielding a lot of power but it depends on what supporting mods you have and how it is being tuned.

    I understand my question will require some research to answer, but if I get the 590hp kit, but am only wanting to get my 2017 Ecoboost to 450hp and roughly the same with Torque so that I am not pushing the turbos limits. Would any other parts of the engine need to be upgraded to allow the set up to run safely and efficiently as a daily driver? (Intercooler, etc)

    • The 590hp cp-e Precision Gen I Atmosphere Turbo Kit can be used for your goals. Final power numbers will depend on your boost level, and several other factors. For a 450hp goal, all you would need to safely run this is an intercooler and a tune.

    Hi, I have a 2017 ecoboost I live in Australia, I'm looking to buy a turbo upgrade kit, is the one you have in stock can be use overseas? Could you please also let me know which additional parts I will need in order to run without problems, I already got a Cobb accessport, Roush air intake filter and exhaust

    • This does have the ability to be shipped overseas with the use of I-parcel, depending on the power goals of the car, it would be recommended into upgrading the engine internals as they are rated to handle up to 450-500 crank horsepower, also, an external wastegate would be required to get with this at the same time. With the tuner you have now it would be required to also get a custom dyno tune for proper operation on the vehicle.

    As stated in a previous question i understand that the model chosen by hp determines the size of the turbo. My question is are there requirments other than an aftermarket tune to use the largest turbo? Seems odd to think you could go from 300hp to 700hp with just tune and a larger turbo. Sorry for the long question. 1 answer

      If you want to beat 5.0's and pretty much anything else that comes your way this is the Kit to do it with! I purchased the 5862 mm kit with the downscream pipe and went for a bit of a smaller turbo with less lag and this set up is perfect! with all the supporting mods and some custom tuning you can daily drive this beast with ease no problem and have that power the EcoBoost truly lacks when you need to pass someone or just want to show those Bad V8's that you can hang with them no problem in your four banger. your MPG will take a pretty good hit when putting this kit on if you plan to Daily it but it is to be expect when your hunting for more speed and power. Install is straight forward and power yielded is great! you will not be disappointed with this kit and will go from ecoboost to ecobeast in no time!
