This is not your average vintage Jeep. Meet the LSXWillys—a 1952 CJ3A Willys Jeep packing modern LSX power, forced induction, and nitrous. With over 750+ wheel horsepower, this street-driven beast proves you can merge classic style with cutting-edge performance.
Powertrain: ProCharged LSX with Nitrous
At the heart of this Jeep is a 4.8L ProCharged LS engine paired with a Nitrous Express direct port system. This combination unleashes massive horsepower on demand while maintaining drivability. The setup has been tuned to perfection with MS3Pro Engine Management, giving precise control over fuel, spark, and boost.

Electronics & Control
The electronics are a big part of why this Jeep works so well.
-
The MS3Pro ECU ensures reliable ignition and fuel delivery under boost and nitrous.
-
The MicroSquirt transmission controller handles seamless shifting for the 4L80E through CAN integration.
This results in a setup that not only makes big power but also works smoothly on the street.
Performance
With 750+ WHP on tap, the LSX Willys is capable of serious dragstrip fun while still cruising comfortably. The combination of ProCharger boost and direct port nitrous makes for explosive power delivery—perfect for burnouts, street pulls, or quarter-mile competition.
Why This Build Stands Out
What makes this Jeep special isn’t just the power—it’s the balance. Retaining a factory suspension keeps the vintage feel alive, while modern engine management and drivetrain upgrades make it reliable and brutally fast.
This Willys is a testament to how far you can push a classic Jeep with today’s technology—an unmistakable mix of old school looks and new school performance.
