what is a turbo on a diesel truck
Turbo-diesel Turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. Turbocharging is common in modern car and truck diesel engines to produce higher power outputs, lower emissions levels, and improved efficiency from a similar capacity of engine.[1] Turbo-diesels in automobiles offer a higher refinement level than their naturally aspirated counterparts.[2]
Engine swap This is done either because of failure, or to install a different engine, usually one that is more modern, this may make it more powerful and or efficient. Older engines may also 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.
