NRE 454 Big Block Twin-Turbo Outlaw – 1000 HP on Pump Gas | Complete Turn-Key Monster Package

The NRE 454 Big Block Twin-Turbo Outlaw is engineered for enthusiasts who want extreme power, uncompromising durability, and a true drop-in solution that redefines what a street engine can be. Designed to deliver an astonishing 1000 hp on 91-octane pump gas, this package is built for long-distance reliability, comfortable drivability, and explosive performance at any altitude. With its self-learning ECU, maintenance-free hydraulic valvetrain, and full accessory system, this is one of the most complete Twin-Turbo big-block packages ever created.

Whether you’re cruising 400 miles in a day with the AC blasting, or unleashing brutal acceleration at the strip, this engine performs flawlessly—while sounding like a wild naturally aspirated big block thanks to its refined cam and turbo design.

Built for Real-World Driving

This engine isn’t just a dyno queen. It was designed to be driven, daily or aggressively, without the fragile nature typical of ultra-high-horsepower builds. The self-learning fuel management system continuously adapts to weather, elevation, load, and driving style, ensuring smooth operation whether you’re in the mountains, desert, or city streets.

The hydraulic roller valve-train removes the need for periodic lash adjustments, offering a truly maintenance-free setup—ideal for long road trips, touring builds, hot rods, pro-touring muscle cars, and high-end show vehicles.
