The Heart of the Sports 800: Engine Specs

The engine that powered the 1965 Toyota Sports 800 was a horizontally opposed, two-cylinder, air-cooled engine, designated as the 2U-B engine. This configuration is often referred to as a boxer engine, known for its smooth operation and compact design. Let's break down the key specifications:

• Configuration: Horizontally Opposed, Two-Cylinder
• Displacement: 790 cc (0.8 liters)
• Cooling System: Air-Cooled
• Valvetrain: OHV (Overhead Valve)
• Bore x Stroke: 82 mm x 75 mm
• Compression Ratio: 8.0:1
• Maximum Horsepower: 45 PS (44 hp) at 5,400 rpm
• Maximum Torque: 6.7 kg⋅m (66 N⋅m; 48 lb⋅ft) at 3,800 rpm
• Fuel System: Two Keihin Carburetors

The choice of an air-cooled engine was quite innovative for its time, providing simplicity and weight savings. The horizontally opposed layout helped to keep the engine's profile low, contributing to the car's overall aerodynamics. The OHV valvetrain was a common design choice in the 1960s, offering a good balance of performance and reliability. The engine's relatively high compression ratio for its time helped to improve its efficiency and power output. Equipped with two Keihin carburetors, the engine was able to deliver a decent performance for a car of its size and weight.

Performance and Driving Experience

When it comes to performance, the 1965 Toyota Sports 800 was no powerhouse, but it offered a lively and engaging driving experience. With just 45 horsepower, the car could reach a top speed of around 96 mph (155 km/h). While that may not sound impressive by today's standards, it's important to remember that the Sports 800 weighed only around 1,279 lbs (580 kg), thanks to its lightweight construction and aluminum body panels.

The combination of low weight and a responsive engine made the Sports 800 feel nimble and fun to drive. The engine's torque curve was well-suited to everyday driving, providing adequate acceleration and responsiveness in city traffic. The four-speed manual transmission allowed drivers to make the most of the engine's power, while the car's independent suspension provided decent handling and road holding.

Driving a 1965 Toyota Sports 800 is an experience that connects you to a different era of motoring. The engine's distinctive sound, the direct steering, and the overall simplicity of the car offer a unique and rewarding experience. It's not about outright speed, but about the joy of driving a well-engineered and beautifully designed classic sports car.

Design and Engineering Innovations

The 1965 Toyota Sports 800 was not just about its engine; it was a showcase of innovative design and engineering. The car's sleek and aerodynamic body was penned by Shozo Sato, and it featured several advanced features for its time. One notable aspect was the use of aluminum body panels, which helped to reduce weight and improve performance. The car also featured a targa top, which could be removed and stored in the trunk, allowing for an open-air driving experience.

The engine itself was a marvel of engineering. The choice of an air-cooled, horizontally opposed engine was relatively rare, and it demonstrated Toyota's willingness to experiment with new technologies. The engine's compact size and low profile allowed for a more aerodynamic body design, while its smooth operation contributed to the car's overall refinement. The use of two carburetors ensured that the engine could deliver adequate power and responsiveness across the rev range.

In addition to its engine and body design, the 1965 Toyota Sports 800 also featured several other innovative features. These included an independent suspension system, which provided better handling and ride quality compared to traditional solid axle setups. The car also had rack-and-pinion steering, which offered more precise and responsive steering feel. All these features combined to make the Sports 800 a truly special and innovative car for its time.

Maintenance and Reliability

Like any classic car, the 1965 Toyota Sports 800 requires regular maintenance and care to keep it running smoothly. The air-cooled engine is relatively simple in design, but it does require attention to ensure proper cooling and lubrication. Regular oil changes are essential, as is cleaning the engine's cooling fins to prevent overheating. The carburetors may also require occasional adjustment and cleaning to maintain optimal performance.

One of the biggest challenges in maintaining a 1965 Toyota Sports 800 is finding parts. As the car was produced in relatively small numbers, parts can be difficult to source. However, there are several specialist suppliers who cater to classic Toyota vehicles, and it is often possible to find the parts you need with some patience and research. Online forums and communities can also be a valuable resource for finding parts and getting advice on maintenance and repairs.

Despite the challenges of maintaining a classic car, the 1965 Toyota Sports 800 is generally considered to be a reliable vehicle. The engine is robust and well-engineered, and with proper care, it can provide many years of service. The car's simple design also means that there are fewer things that can go wrong, compared to more modern and complex vehicles. With regular maintenance and attention, a 1965 Toyota Sports 800 can be a rewarding and enjoyable classic car to own.
