The Aurora 2000 Turbo Kit is the foundation of all ATS turbo systems, designed for everyday driving and extreme towing. The factory turbo charger is small and not designed for extremely heavy towing. When pulling heavy, the factory turbo charger falls short on airflow. The lack of airflow causes high EGTs that are very harmful to your engine. The Aurora 2000 turbine section of the turbo charger is perfectly matched to the volumetrics of the 5.9L Cummins engine. This means there is no wastegate in the turbine housing wasting valuable heat energy developed by the engine. Boost pressures between 32 to 38 PSI are optimal for the Aurora 2000 turbo system. Due to the perfect balance of the Aurora 2000 turbo system there is an increase in economy over the stock turbo charger. Mate the Aurora 2000 turbo charger with our Pulse Flow exhaust manifold and Arc-Flow intake manifold for maximum airflow with minimum airflow restriction. 








For maximum power and boost, there is just no substitute for The Aurora 5000 Turbo. The Aurora 5000 utilizes a five inch compressor intake and is capable of boost levels of over 60 PSI. This is the only single turbo production kit available that is capable of producing power levels of over 600 HP on diesel fuel alone while allowing street driver manners.

The Aurora MST (Multi Stage Turbo) is the latest innovation from ATS. As wasted exhaust
energy from the engine enters the turbine section of the turbo, the exhaust flow is diverted into only one volute section by a variable valve. This allows quick spool up of the turbo at low
speeds. As the variable valve opens for increased air flow, the exhaust is opened to both volute sections of the turbo, allowing the engine to " breath." This reduction in exhaust pressure increases engine efficiency, reduces exhaust temperatures, and increases economy. Now you have that "big turbo" performance with small turbo spool up. A key element of proper turbo sizing is the delicate balance between exhaust pressure and intake boost pressure. The innovative design of the Aurora MST automatically balances the pressures, optimizing turbo efficiency and response.

The response of the variable valve can be adjusted by using the adjustment screw to dial it in for your unique engine configuration. We have also engineered into the design an internal wastegate to protect from an overboost condition. The wastegate can also be adjusted for the exact max boost level desired.
