2025 Chevrolet Corvette Stingray Z51 w/ Lingenfelter 427 Engine Package
Project Overview
Straight off the showroom floor with just 5 miles on the odometer, this 2025 Corvette Stingray Z51 came to KTR for a transformation. It became the first 2025 Corvette to have its ECM unlocked by Trifecta Performance, opening the door for a complete powertrain swap. With a Lingenfelter-built 427ci LT2 under the hood and supporting upgrades, this Stingray preserves showroom polish while unlocking a new tier of power and response.

Engine & Powertrain
After completing the 500-mile break-in, the factory LT2 was removed to make way for a Lingenfelter 427ci LT2 engine package. Supporting mods included:
Billet intake manifold from Wilson Manifolds
Nick Williams 103mm throttle body
Haltech cold-air intake system
GForce Outlaw half-shaft axles for added strength
Together, these components give the Stingray a broad torque curve, improved drivability, and drivetrain durability to handle the added power.
Exterior & Finishing Touches
Beyond the powertrain, the details make this build stand out. Custom Lingenfelter badges by Billet Badges, painted carbon flash black, were installed to match the ACS skirt kit. The result is a subtle yet unmistakable visual cue that this Stingray is anything but stock.
