Build Core Engine – What You Need to Know

This is a Build Core Engine, not a plug-and-play unit. A clean, rebuildable core is required to begin the process. During remanufacturing, your core is fully disassembled, carefully machined, and rebuilt with upgraded or reconditioned parts. The quality of your core directly affects the final engine’s performance and lifespan.

Your core must be complete, undamaged, and free of excessive wear. For guidance on what qualifies, contact us or check our Help Center before ordering.
