FAQ
What makes this different from a complete short block?This is a DIY, fully machined and blueprinted kit of short block components you assemble yourself—ideal when you want control over clearances and build details while saving on assembly labor.
Does it include fuel system or turbo parts?No. It’s an unassembled short block package. Pair it with the correct CP3, injectors, and turbo system for your goals.
Is a core charge required?Yes. A refundable core charge typically covers the block, crank, rods, cam, and the shipping crate. Return acceptable cores to recover the charge.
What break-in procedure do you recommend?Use dedicated break-in oil for the first 300–500 miles, vary RPM/load, avoid extended idling, and change oil & filter after break-in.
