This page carries the ATS Diesel Performance Aurora Compound Turbo Upgrade. Know this first: a weak exhaust brake and low boost on this truck often point to a sticking factory turbo, and that is a repair job, not a reason to add a second turbo.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"sds-copy-guide\"\u003e\n\u003ch2\u003eCompound turbos on the 2019-2024 Ram 6.7L Cummins\u003c\/h2\u003e\n\u003cp\u003eFrom the factory, this engine runs a single Holset HE300VG variable-geometry turbo, revised for 2019 with taller vanes, heavier-duty bearings and a forged-milled compressor wheel, good for up to 33 psi. That turbo also makes the exhaust brake. A compound setup stages two turbochargers in series, so one turbo feeds pressurized air to the other. It is a bigger job than swapping a turbo: more plumbing, more parts and more decisions about how the system works with the rest of the truck. Read the ATS listing for exactly what the kit includes and what it works with.\u003c\/p\u003e\n\u003ch2\u003eFix the stock turbo first\u003c\/h2\u003e\n\u003cp\u003eIf the truck feels down on power, rule out a tired factory turbo before you plan a compound build. The classic problem on this engine is soot and oil coking on the vane ring and pivots. The exhaust brake fades first, then you get low or erratic boost, black smoke, high EGTs and limp mode, commonly between 50,000 and 150,000 miles. If that sounds like your truck, a direct-replacement HE300VG keeps the exhaust brake, EGR and DPF\/SCR compatibility and runs on factory tuning. Diagnose first, then decide whether you are fixing a problem or building something new.\u003c\/p\u003e\n\u003ch2\u003eWhat we carry\u003c\/h2\u003e\n\u003cp\u003eThe kit on this page is the \u003ca href=\"\/collections\/ats-diesel\"\u003eATS Diesel Performance\u003c\/a\u003e Aurora Compound Turbo Upgrade, listed for 2019-2024 6.7L Cummins trucks.

Both are the versions ATS intends for trucks with custom tuning. ATS also builds 202-962-2464 and 202-964-2464, which include Intelliboost for trucks on factory tuning. Read the installation notes below before you order.\u003c\/p\u003e\n\u003ch2\u003eWhy this part\u003c\/h2\u003e\n\u003cp\u003eThe factory variable-geometry turbo on this engine has a known weak spot. Soot and oil coke the vane ring and pivots, so the exhaust brake fades first, then boost turns low or erratic, with black smoke, high EGTs and limp mode, commonly somewhere between 50,000 and 150,000 miles. The electronic actuator can also fail on its own, which takes the exhaust brake with it. If you are facing a turbo replacement anyway, or you want more from the truck than one turbo can give, this kit swaps the factory turbo for two new ones.\u003c\/p\u003e\n\u003cp\u003eATS has been building compound turbo systems since the early 2000s. In this kit the smaller VFR high-pressure turbo, with a 60mm or 64mm billet compressor wheel, sits in the factory location and gives immediate low-RPM response. The large Aurora 6000 low-pressure turbo mounts over it, which makes the most of the space and keeps airflow efficient, and it supplies the air volume for the top end. ATS says the result is a broad power band, lower EGTs and the reliability heavy-duty use calls for.\u003c\/p\u003e\n\u003cp\u003ePower support depends on the high-pressure turbo. The 3000\/6000 system supports up to 750hp \/ 1400ft lbs. The 4000\/6000 system supports up to 900hp and 1750ft lbs. With two turbos sharing the work, the system can make boost pressures exceeding 60 PSI, and ATS strongly recommends head studs if you will run more than 45 PSI.\u003c\/p\u003e\n\u003cp\u003eATS also points to fuel economy. More air gives more complete combustion, and ATS says the denser oxygen charge reduces heat stress on the 6.7L, prolongs engine life and improves fuel efficiency during heavy hauls.\u003c\/p\u003e\n\u003cp\u003eHeat is handled with coatings. The turbine housings on both turbos, the Vortex transfer manifold and the included ATS Pulse Flow exhaust manifold are finished in a high-temp black ceramic coating. It traps heat to drive the turbos more efficiently and is rated for substrate protection up to 1600°F and environmental protection up to 2000°F.
