2015-2016 Ford 6.7L Powerstroke Compound Turbo Kits

Compound turbos on the 2015-2016 Ford 6.7L Powerstroke

From the factory, 2015-2016 pickups use one turbo: a Garrett GT3788V variable-geometry unit with a 72.5 mm turbine, an 88 mm compressor, a hydraulic vane actuator and no wastegate. It sits in the valley between the reverse-flow heads, and its charge air is cooled by an air-to-water charge-air cooler on the secondary cooling loop. That valley-mounted single VGT is the only configuration Ford built for this pickup. Ford sized it up for 2015, crediting the larger turbo for 440 hp, 860 lb-ft and stronger exhaust braking when towing. A compound kit changes that layout by adding a second turbo, which means new mounting, new plumbing and more parts under the hood than any drop-in. The rest of our 6.7L parts are on the Powerstroke hub.

Before you go compound

If you are here because the truck lost power, make sure it is not a boost leak first. The factory cold-side intercooler tube is plastic, goes brittle and cracks, and the hot-side connection can pop off the turbo outlet under load. That shows up as sudden power loss, P0299, P1247 or P0402 and limp mode. The GT37 itself has no widely documented failure pattern in the sources we use, so rule out leaks and oil-supply problems before you blame it. A compound kit should be a choice you make for how you use the truck, not a fix for a cracked tube.

Stock replacement vs. upgrade

You have three paths on this truck. Keep the factory GT3788V and maintain the plumbing around it. Swap in a drop-in turbo that uses the factory location and keeps a single-turbo layout. Or build a compound setup, which is the largest step in parts, labor and fitment checking. The stock turbo already brought this engine to 440 hp and 860 lb-ft with factory exhaust braking, so a compound kit makes sense when you have a specific goal the single turbo does not meet and you are ready for a bigger install. Whatever you build, the factory DOC, DPF, SCR and EGR system stays in place and working.

Fitment notes

These kits list wide year ranges, and the 2015-2016 truck sits between two splits. Ford replaced the 2011-2014 DualBoost turbo with the GT3788V for 2015, so DualBoost-specific hardware such as vacuum wastegate parts and SST charge pipes does not apply to your truck, and downpipe catalogs split at 2014/2015. Ford then changed the turbo oil supply line and pedestal for 2017, so 2015-2016 parts are not directly cross-compatible with 2017-2019. Read each kit's listing to confirm it covers the 2015-2016 pedestal and oil feed. Chassis cabs run a Garrett AVNT3276V, not the pickup turbo, so confirm a kit lists your body style. On emissions: we have not found a compound kit for the 2015-2016 6.7L that carries a CARB Executive Order number. Call us before you order and we will go over the emissions paperwork with you. Verify by VIN either way.

Frequently asked questions

Is there a CARB-legal compound turbo kit for a 2015-2016 6.7L Powerstroke?

Not that we have found. None of the sources we use shows a compound turbo kit for this engine with a CARB Executive Order number, which is the document that proves an aftermarket part is emissions-legal in all 50 states. Call the shop before you order and we will go over the paperwork for the kit you are considering.

Will a compound kit listed for 2011-2019 fit my 2016 F-350?

It can, but read the details. Ford changed the turbo to the GT3788V for 2015 and changed the oil supply line and pedestal for 2017, so a kit covering 2011-2019 needs the right hardware for the 2015-2016 middle years. Check the listing for what is included for your year, and verify by VIN.

Should I go compound or buy a drop-in turbo?

A drop-in keeps the factory single-turbo layout and is the smaller job. A compound kit adds a second turbo and brings more plumbing, mounting and fitment checking. If your goal is to get back to factory performance, fix any boost leaks and look at drop-ins first; go compound when you have a specific build goal and are ready for the bigger install.

Do these kits fit a chassis cab?

Check carefully. The 2011-2016 F-350, F-450 and F-550 chassis cabs use a Garrett AVNT3276V and are rated at 300 hp and 660 lb-ft, not the pickup's GT3788V setup. The kits here are listed by engine and year, so confirm on the product page that your chassis-cab truck is covered before ordering.
