Build Core Engine Notice

This listing is for a Build Core Engine, not a ready-to-install unit. A clean, rebuildable core is required as the foundation for remanufacturing.

During the rebuild process, the engine is fully disassembled, inspected, machined, and reassembled with new or reconditioned components. To guarantee performance, your core must be complete, free of cracks, and without excessive wear. If you have questions about what qualifies, contact our team or visit our Help Center for details.
