Specific displacement around 1497cc. Power output typically in the 70-85 hp range depending on tuning and carburation. 1600Cc: Nissan R-series OHV inline-4. Specific displacement around 1595cc. Increased power output compared to the 1500cc. Details on camshaft profiles and carburetion are crucial. 2000Cc: Nissan R-series OHC inline-4. Specific displacement around 1982cc. Known for significantly improved performance, often producing 130-145 hp. This engine was a key upgrade for enthusiasts. Performance Carburetion: Commonly equipped with twin SU carburetors (e.g., HJB 38W Type) or Hitachi carburetors, requiring specific tuning and synchronization procedures detailed in the manual. Fuel System Fuel Type: Premium Unleaded Gasoline (as per era specifications; modern equivalents should be considered). Maintenance Items Spark Plugs: Specific spark plug types and gap settings will be detailed. For example, NGK or Champion equivalents would be common. 🔧 Transmission Standard Gearbox Options: Primarily 4-speed manual transmission. The later SPL 311 and SR 311 models also offered a 5-speed manual transmission option, significantly improving highway drivability. Optional Automatic Transmission: Not typically offered or common in these early sports roadsters; manual transmission was the standard and defining characteristic. Features Clutch Type: Single dry plate, diaphragm spring clutch, serviced by adjusting clutch free play and replacing friction disc and pressure plate as needed. Fluid Specs Transmission Fluid: Typically GL-4 rated manual transmission fluid (e.g., SAE 80W-90 or SAE 75W-90, check manual for exact specifications). 📐 Dimensions Exterior Body Style: Two-door convertible roadster. Weights Curb Weight: Approximately 1900-2100 lbs (860-950 kg) depending on engine and equipment. Gross Vehicle Weight Rating: Specifies maximum permissible weight including vehicle, passengers, and cargo. Detailed in the manual. 🛡️ Safety Features Ratings Crash Test Information: As a vehicle from the 1960s, formal crash safety ratings in the modern sense are not applicable. The manual would detail structural integrity and any specific safety-related components of the era. Active Features Braking System: Front disc brakes and rear drum brakes were common on later models (e.g., 1600cc and 2000cc), while earlier models might have featured all-around drum brakes. Brake fluid specifications (DOT 3) and bleeding procedures are vital. Passive Features Seatbelts: While not standard on all early models, seatbelt anchor points and installation guidance would be critical, as would be information on replacing seatbelt mechanisms. 💡 Technology Features Infotainment Audio System: Basic AM radio was common. The manual would cover radio removal, installation, and basic electrical connections. Driver Assistance Features: No electronic driver assistance systems as we know them today. Focus is on mechanical and electrical systems. Connectivity Features: N/A 🔧 Maintenance Service Intervals Oil Change: Typical intervals would be every 3,000-5,000 miles or 3-6 months, depending on usage. Manual will specify exact mileage and time intervals. Tune Up: Regular tune-ups including spark plug replacement, ignition timing adjustment, carburetor synchronization, and filter changes...
