Build Core Engine โ Important Notice
This is a Build Core Engine listing, which means it is not a ready-to-install motor. We require a good, rebuildable core to remanufacture. During the process, your engine is fully disassembled, inspected, machined, and rebuilt with new or upgraded components. The condition of your core directly impacts the final reliability of the engine.
Make sure your core is complete, free of major cracks, and not missing key parts. If youโre unsure about what qualifies, visit our help center or contact our team before purchasing.
