Motor Replacements

An  engine swap  is the process of removing a car's original engine and replacing it with another. This is done either because of failure, or to install a different engine, or to usually one that is more modern and so more efficient, this may make it more powerful and or economical. Older engines may have a shortage of spare parts and so a modern replacement may be more easily and cheaply maintained. Swapping to a diesel engine for improved fuel economy is a long established practice, with modern high efficiency and torque diesel engines this does not necessarily mean a reduction in performance associated with older diesel engine swaps. For the particular application of off-road vehicles the high torque at low speed of turbo diesels combined with good fuel economy makes these conversions particularly effective. Older non-electronic fuel injection diesels were well known for their reliability especially in wet conditions. An engine swap can either be to ...

An  automobile engine replacement  is an  engine  or a major part of one that is sold individually without any other parts required to make a functional car (for example a  drivetrain ). These engines are produced either as  aftermarket  parts or as reproductions of an engine that has gone out of production. Use Types of replacement engines Remanufactured engines (also known as "reconditioned" or "re-engineered") Rebuilt engines Used engines New engines (also known as "crate engines") "Short block" - everything between the cylinder head and the oil pan (excluding those items) "Long block" - a short block, with mounted and gasketed cylinder head, valves and camshaft "Crate engine" - often more than a long block, including intake manifold, and carburetor or fuel injection system, and perhaps an alternator Replacement blocks Terminology Replacement engines are used to replace classic car en...
