Alfa Romeo Giulia 105/115 TI Super 1570 cc Twin-Cam Engine
The TI Super paired Alfa Romeo’s 1570 cc twin-cam four-cylinder engine with two twin-choke carburettors, delivering a museum-listed 112 CV at 6500 rpm.
The TI Super engine
This record covers the 1570 cc engine installation in the Giulia TI Super, within the 105/115 saloon generation. Alfa Romeo introduced the TI Super in 1963 as a competition-oriented Giulia saloon. Its engine helped establish the model’s sporting identity, combining twin overhead camshafts with twin-carburettor induction. Alfa Romeo’s retrospective describes the TI Super as a ready-to-race derivative and credits it with a category victory in the 1963 Tour de France Auto. Alfa Romeo history.
Construction and factory specification
The museum specification describes a front-mounted, longitudinal inline-four with a light-alloy block and cylinder head. Bore and stroke are 78 × 82 mm, giving 1570 cc. Two overhead camshafts operate two valves per cylinder through a double-chain timing arrangement. Induction uses two twin-choke carburettors; ignition employs a distributor, and lubrication uses a wet sump.
Alfa Romeo’s museum lists 112 CV at 6500 rpm. The original CV unit is retained here rather than relabelled as an unspecified horsepower rating. The engine drives the rear wheels through a dry single-plate clutch and five-speed gearbox. These specifications describe the TI Super installation; they should not be transferred automatically to every 1570 cc Giulia engine. Museo Alfa Romeo technical record.
Production and homologation chronology
The supplied intake reference lists TI Super vehicle production in 1963–1964. Those are production years, not a market-specific model-year designation or a documented manufacturing interval for replacement engines. Giulia production chronology.
The FIA identifies the Italian Giulia TI Super as a four-cylinder, 1570 cc, rear-wheel-drive car under homologation number 1267, Group T. It records homologation on 14 January 1964 and its end on 1 January 1972. Neither date establishes when engine manufacture began or ended. The sources reviewed do not establish a separate TI Super engine-production total or a specific engine assembly plant. FIA homologation record.
Application and identification
This page concerns the TI Super saloon’s engine specification, rather than the entire Alfa Romeo twin-cam family. The catalogue separately records the Giulia Super 1570 cc engine beneath the later Super variant. Shared displacement alone does not establish identical tuning or equipment.
The figures above describe the documented TI Super specification. No separate export-market calibration, competition modification or subsequent replacement-engine specification is asserted.
