⚙️ Engine Specifications

Engine Type:

Inline 4-cylinder, DOHC (Double Overhead Camshaft)

Engine Displacement:

1779 cc (1.8 Liters)

Horsepower:

Approximately 130-138 hp (depending on specific market and tuning)

Torque:

Approximately 170-180 Nm (125-133 lb-ft) at 3000-3500 RPM

Fuel Delivery:

Twin Weber or Dell'Orto carburetors (e.g., 40 DCOE or similar) for European models, often fuel injected in later iterations or specific markets (though 1750 is primarily carbureted).

Engine Code Designation:

Often referred to by chassis code or internal designation, with the '1750' indicating the displacement.

🔧 Transmission

Transmission Type:

5-speed manual transaxle (gearbox and differential integrated into a single unit mounted at the rear for better weight distribution).

Rear-mounted transaxle, de Dion rear axle configuration.

Clutch Type:

Single dry plate, hydraulically operated.

📐 Dimensions

Body Styles:

Berlina (4-door sedan), GT (2-door coupe), Spider (2-door convertible).

Wheelbase:

Approximately 2500 mm (98.4 inches)

Curb Weight:

Approximately 1000-1200 kg (2200-2650 lbs) depending on body style.

Weight Distribution:

Excellent due to rear-mounted transaxle.

🛡️ Safety Features

Safety Standards Era:

Designed to 1960s/1970s safety standards, less emphasis on modern passive safety features.

Seatbelts:

Likely lap belts standard, optional three-point belts available.

Construction:

Steel unibody construction.

💡 Technology Features

Infotainment System:

Basic AM/FM radio, optional upgraded period-correct stereo.

Connectivity Features:

None.

🔧 Maintenance

Oil Change Interval:

Every 3,000-5,000 miles or 6 months, depending on usage. Use high-quality oil with ZDDP additive.

Tune Up Interval:

Spark plugs and points approximately every 6,000-10,000 miles. Carburetor adjustment as needed.

Engine Oil Specification:

API SG or higher, SAE 20W-50 recommended. Crucially, requires oil with ZDDP for flat tappet camshafts.

Coolant Specification:

50/50 mixture of ethylene glycol antifreeze and distilled water. Check for corrosion inhibitors appropriate for older engines.

Brake Fluid Specification:

DOT 3 or DOT 4.

Gearbox Oil Specification:

SAE 75W-90 or 80W-90 API GL-4 manual transmission fluid.

Rear Axle Differential Fluid:

SAE 90 API GL-5 (check manual for specific recommendation, but GL-4 is often preferred for older gearboxes).

Common Problems:

Carburetor tuning and synchronization, electrical system reliability (aging wiring), rust (especially around wheel arches, sills, and floor pans), potential wear on suspension bushings and ball joints, clutch slave cylinder leaks.

Rust Prone Areas:

Rear wheel arches, 'step' area behind front wheels, inner sills, floor pans, A-pillars.
