Prior to shell preparation and painting, we took the opportunity to do a dry installation of the V6 engine and gearbox to design and manufacture any bespoke parts required for the job and make any necessary modifications to the engine bay prior to painting.
We sourced a brand new crate 3.0 V6 24v from Fiat/Alfa in Italy for the project, it will need new cambelts having sat for many years, but being brand new was the best basis to start from.
We sourced an Alfa 6 oil sump and oil pump pickup which fits directly to the v6 block but is the 105 style wing shape. This means that the engine cross member does not need to be cut during the installation, a significant advantage over using a normal FWD sump. With special engine mountings fabricated the engine dropped straight in with relative ease. We sourced a special bellhousing which adapts a 105 series gearbox to fit directly to the v6 engine block. With the engine and gearbox fixed in its final position, we fabricated a bespoke 304 marine grade tubular exhaust system. For ease of running and future use, we decided to plumb the engine with the standard factory ECU and Bosch Motronic ancillary systems. The FWD intake plenum, sat on top of the right hand head would not clear the Spider bonnet, so we custom fabricated a new aluminium intake plenum, located further down, and extended the intake runners to match. A custom inlet run was made from the throttle body to the free flow air filter via the airflow meter to avoid having to cut clearance room at the bulkhead, resulting in a neat installation. A custom radiator has been made which sits further forward to give enough space to fit top and bottom radiator hoses to the engine, this radiator has a special header tank for filling.
