Hi all,
The 'G' model Esprit Turbos incorporated a cooling fan in the engine cover. This fan draws cool ambient air and forces it down across the carburetters to prevent vapor lock on a hot restart. Also, the interior of the engine cover is shaped such that this air is then directed past the turbo and exhaust manifold, assisting in their cool down before being vented to atmosphere through the rear driver side wheel arch
The fan is operable only when the ignition is turned off. The fan and a circuit timer are activated by a thermal switch located under the engine cover. The fan deactivates when: a. the thermal switch opens due to a cool condition, or b. when the timer (located on the inside cover of the ignition box) trips after 15 minutes to prevent battery drain. Hope this helps...Jim '85TE

'83 turbo,
This may have been a US Model varient as I have a friend who also owns an '83 and has this as well. I have also seen it on 1980 models, the first year Esprit Turbo in the US.
It should not be thought of in terms of operative engine cooling as the draw would be insufficient to offset the normal engine bay airflow once the car is at speed. Hope this helps...Jim '85TE
