Brabus 7.3L V12 Engine Kit | Used OEM High-Performance

Description

For sale is a used Brabus 7.3L V12 engine kit, a complete high-performance powerplant originally engineered and built by Brabus for applications requiring serious power and durability. This unit has been carefully removed from a donor vehicle and stands as a solid base for performance builds, restorations, or custom engine swaps. The engine remains in good used condition, showing typical surface wear from prior use but no signs of catastrophic damage. All major components — including the block, heads, crankshaft, and core accessory mounts — are present and ready for inspection or installation after refresh.
This Brabus 7.3 V12 kit is valued by performance and classic vehicle enthusiasts for its combination of displacement, design strength, and elevated power potential compared with standard V8 or V12 alternatives. It offers a rare opportunity to bring vintage or custom projects to life with genuine Brabus hardware.
Performance & Reliability:
The Brabus 7.3 V12 was originally developed as a high-output variant of the Mercedes-Benz M120 platform, featuring larger displacement and performance-oriented internals. Brabus reworked the block, cylinder head porting, and breathing systems, resulting in significant torque and horsepower gains over stock V12 engines.
Before listing, the engine was inspected for:
Compression consistency across all 12 cylinders
No visible block cracks or major casting damage
Smooth rotation of the crankshaft and camshafts
Intact core mounts and accessory bosses
The internal bearings and journals show typical signs of use but remain without scoring or excessive wear. The block and head surfaces are straight and free of visible damage. The kit is ideal for a full professional rebuild, which is recommended to refresh seals, gaskets, timing components, and service items before installation.
This engine kit does not include fluids, electronics, or accessories like an ECU, wiring harness, intake, or exhaust components — buyers should plan to match compatible ancillary parts for their specific project.
Fitment:
Fits in:
Classic Mercedes-Benz models originally equipped with Brabus 7.3 V12 swaps or compatible with the M120 platform
