NRE Twin-Turbo Alien 572 – Hot Rod Series | 2,000 HP Twin-Turbo EFI Big Block

The NRE Twin-Turbo Alien 572 Hot Rod Series represents the pinnacle of street-driven twin-turbo big-block performance. Producing an astonishing 2,000 horsepower at 6,200 RPM and 1,700 ft-lbs of torque at 5,100 RPM, this engine delivers extreme power while remaining a fully dyno-tuned, ready-to-run package capable of being driven on real roads anywhere in the world.

Developed using over 25 years of twin-turbo big-block engineering experience, this combination offers unmatched dollar-for-dollar value in the high-horsepower turbo market. The NRE Alien system integrates advanced EFI technology, precision airflow management, and direct-fit stainless turbo manifolds to simplify installation while maintaining OEM-level drivability at cruising speeds. This is not a race-only engine—it’s a street-capable monster built to dominate.

Extreme Performance With Real-World Usability

Despite its massive power output, the Twin-Turbo Alien 572 is engineered for predictable throttle response and controlled power delivery. The low-shock solid roller camshaft, high-efficiency turbo system, and fully sequential EFI allow this engine to behave calmly at part throttle while unleashing brutal acceleration under boost. Whether installed in a high-end hot rod, pro-touring build, or extreme street machine, this engine delivers controlled violence with modern reliability.

The NRE Alien intake keeps the system compact with hidden injectors, sensors, and an internal twin throttle body, maintaining clean packaging while supporting enormous airflow. Every engine is fully dyno-tested and calibrated before delivery.
