Crate engines are manufactured by many different companies, but they all share the same characteristics of being complete engines nearly ready to install once removed from the crate. Generally a crate engine still will require additional parts to be fitted, which can range from minor (engine oil dipstick) to major (intake manifold and fuel injection system), depending on the engine package purchased and the targeted vehicle application. This type of engine has various applications including general replacement, hot rod builds, and motorsports competition. Crate engines are often seen as an economical and more reliable solution as opposed to engine overhauls or custom builds. Such engines are built by specialist engine builders, working in clean and well-equipped workshops, rather than general purpose repair garages.
