This is an "Essential" short block assembly, so you will need to reuse several of your original external components. Key parts to transfer include the cylinder head, oil pan, oil cooler housing, and timing cover. — The DJPSB100022 short block is designed for shops and experienced owners looking to reduce project costs by reusing their factory bolt-on parts. In addition to major components like the oil pan and timing cover, you must also transfer your complete cylinder head assembly, fuel system, turbocharger, and all other engine accessories. This block is the core foundation, which has been professionally remanufactured with new internal pistons, bearings, and gaskets for a "zero-hour" refresh. Before starting your engine build, it is critical to inventory your original components and ensure they are clean and in good working order for the transfer.
