Engine rebuild of a 1987 3.3 Turbo

This car came to us having been stood under a tree outside for 11 years. The engine would not run before the rebuild and was found to have a faulty CDI box, 2 x fuel pumps, fuel distributor, injectors, ignition leads and broken cylinder head studs and was in a very sorry state. Before the engine could be restarted the fuel tank was cleaned and the 11 year old fuel was replaced, the key was finally turned and the engine was reborn.
