The \u003cstrong\u003eATS Aurora Compound Turbo System\u003c\/strong\u003e is the definitive solution for drivers who refuse to compromise between low-end responsiveness and top-end power. By replacing the restrictive factory single turbo (OEM 68444771AB), this kit transforms your RAM into a high-efficiency towing and street machine.\u003c\/p\u003e\n\u003cp\u003eSince the early 2000's, ATS Diesel has pioneered compound turbo technology. This system utilizes a high-pressure (HP) VFR turbo - featuring either a \u003cstrong\u003e60mm or 64mm Billet Compressor Wheel\u003c\/strong\u003e - for instant spool-up and a massive Aurora 6000 low-pressure (LP) turbo for atmospheric volume. The result? A broad, relentless power band, significantly lower EGTs, and the reliability needed for heavy-duty applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Product Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMassive Power and Torque: Achieve incredible performance gains tailored to your needs. The 3000\/6000 system supports power up to 750hp\/1400ft lbs, while the 4000\/6000 system supports up to 900hp and 1750ft lbs. By sharing the workload across two units, this system generates boost pressures exceeding 60 PSI (head studs are strongly recommended if exceeding 45 PSI).\u003c\/li\u003e\n\u003cli\u003eSuperior Thermal Management: To ensure maximum efficiency, the turbine housings on both turbos, the Vortex transfer manifold, and the included ATS Pulse Flow exhaust manifold are finished in a high-temp ceramic coating. This traps heat to drive the turbos more efficiently while providing substrate protection up to 1600 degrees Fahrenheit and environmental protection up to 2000 degrees Fahrenheit.\u003c\/li\u003e\n\u003cli\u003eEliminate Turbo Lag: By mounting the large Aurora 6000 turbocharger over the smaller high-pressure turbo, the system maximizes space and airflow efficiency. The smaller VFR primary turbo (available in 60mm or 64mm configurations) provides immediate low-RPM response while the secondary Aurora 6000 delivers massive top-end volume.\u003c\/li\u003e\n\u003cli\u003eLower EGTs and Better MPG: More air means more complete combustion. By providing a denser oxygen charge, this kit reduces heat stress on your 6.7L Cummins, prolonging engine life and improving fuel efficiency during heavy hauls.\u003c\/li\u003e\n\u003cli\u003eThe One-and-Done Install: We take the guesswork out of the shop. Every single nut, bolt, washer, hose clamp, reinforced silicone boot, and gasket is included. This is a comprehensive solution designed for a one-time install - set it up once and never worry about your turbo system hardware again.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eATS Intelliboost: Intelligent Airflow Calibration:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eChoosing the right kit depends on your vehicle's current tuning state. The \u003cstrong\u003eATS Intelliboost Controller\u003c\/strong\u003e is the critical link that allows your RAM to recognize and utilize the massive increase in airflow without triggering diagnostic errors or derate modes.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFor Factory Calibrations: If your vehicle is running the factory Dodge\/RAM tuning, you must use the kit with the Intelliboost electronics. The Intelliboost controller handles all necessary airflow calibrations in real-time, ensuring the ECM remains happy with the new compound turbo volume.\u003c\/li\u003e\n\u003cli\u003eFor Third-Party Custom Tuning: If your vehicle has already been professionally tuned via third-party software that specifically accounts for compound turbo airflow, the calibration is already handled. In this case, you can opt for the without electronics kit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Product Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual Turbo Precision: Includes two brand-new turbochargers. The primary HP turbo features a new updated actuator and is mounted in the factory location. The Aurora 6000 atmospheric turbo features a 75mm compressor wheel inducer, 88mm turbine wheel inducer, 1.10 A\/R, and a large T-4 turbo flange.\u003c\/li\u003e\n\u003cli\u003eVortex Exhaust Transfer Manifold: Specifically engineered for a compact footprint and smooth exhaust gas travel between units, ensuring simple installation and maximum airflow efficiency.\u003c\/li\u003e\n\u003cli\u003eCeramic Coated Protection: Turbine housings, the transfer manifold, and the ATS Pulse Flow exhaust manifust all feature a clean black ceramic finish that withstands substrate heat up to 1600 degrees Fahrenheit and protects the engine bay environment up to 2000 degrees Fahrenheit.\u003c\/li\u003e\n\u003cli\u003eCustom Coolant Management: Includes an ATS aluminum coolant reservoir designed for factory placement, clearing the necessary room for the large Aurora 6000 and associated plumbing.\u003c\/li\u003e\n\u003cli\u003ePremium Plumbing and Connections: Features reinforced silicone boots for high-pressure connections and an all-new A\/C line that routes around the large turbocharger without requiring bending of the factory lines.\u003c\/li\u003e\n\u003cli\u003eAdvanced Heat Shielding: Includes an ATS T4 turbo blanket for the Aurora 6000, capable of withstanding 2500 degrees Fahrenheit peak and 1800 degrees Fahrenheit sustained heat to keep under-hood temperatures at a minimum.\u003c\/li\u003e\n\u003cli\u003ePulse Flow Manifold: Includes the ATS Pulse Flow 6.7L exhaust manifold with premium gaskets and ultra-strong 12.9 grade hardware for ultimate clamping force and reliability.\u003c\/li\u003e\n\u003cli\u003eComplete Install Kit: Includes a new exhaust downpipe for the Aurora 6000 and all necessary oil feed\/drain lines using high-quality stainless steel braided crimp lines and steel An fittings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Compatibility and Fitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMake: RAM \/ Dodge\u003c\/li\u003e\n\u003cli\u003eModel: 2500, 3500 Pickup\u003c\/li\u003e\n\u003cli\u003eYears: 2019, 2020, 2021, 2022, 2023, 2024\u003c\/li\u003e\n\u003cli\u003eEngine: 6.7L Cummins Turbo Diesel\u003c\/li\u003e\n\u003cli\u003eReplaces OEM Part: MOPAR 68444771AB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATS Diesel","offers":[{"title":"Default Title","offer_id":51212687540502,"sku":"ATS-202-965-2464","price":10111.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0930\/0878\/9782\/files\/0_202-965-2464-fsmf_normalized.jpg?v=1777467349","url":"https:\/\/www.cspracing.com\/products\/ats-diesel-202-965-2464","provider":"Complete Street Performance","version":"1.0","type":"link"}
