1952 SIATA Daina Gran Sport Cabriolet

SL 0255 BroadItaly
Engine
1.4L OHV inline-four, dual Weber 32 DRP.5 carburetors, 65 bhp
Colour
Neptune Blue

A SIATA Daina Gran Sport cabriolet, one of no more than 50 examples built, featuring steel coachwork by Stabilimenti Farina and an aluminium bonnet. Delivered new to California, the car passed through several owners in Ventura County before relocating to Arizona and then the American interior. Its original drivetrain was lost during a period when V-8 conversions were fashionable, but a subsequent owner undertook a four-year rotisserie restoration targeting complete originality, sourcing a correct Fiat 1400 engine and gearbox and refurbishing the original Siata intake manifold.

Maintenance & restoration

  1. 2008Restoration
    Pierce Manifold

    A four-year rotisserie restoration targeting complete originality, guided by period photographs and historical documentation. A correct Fiat 1400 engine and gearbox with a Siata floor-shift conversion were sourced and fitted. The surviving Siata intake manifold with cast-brass Weber carburettors was rebuilt and reinstalled. A new wiring harness with correct aluminium tags was fabricated, new windshield glass fitted, brightwork re-plated or polished, Veglia instruments refurbished, and a new folding hood in period-correct rubberised canvas with aluminium and acrylic side curtains installed. The body was painted Neptune Blue and the interior trimmed in tan leather with black leatherette and rubber mats.

    Restoration commenced shortly after acquisition in early 2008 and lasted approximately four years; Pierce Manifold in California handled the intake manifold rebuild specifically.

  2. Modification

    American V-8 engines were installed by various California-based owners, replacing the original Fiat 1400 drivetrain, which was subsequently lost.

    Described as a common practice of the era; exact date and number of conversions unknown.
