• Transmission: 5-Speed LSD (Limited Slip Differential)
• Body Type: 2-Door Hatchback
• Horsepower: 180 hp (approximately)
• Torque: 130 lb-ft
• Performance: Excellent handling, high-revving nature, and solid reliability

The B18C Engine: Power and Precision

The B18C engine is part of Honda’s famous B-series family, known for its performance and tuning potential. This engine was specifically designed for the SiR-G and features VTEC, Honda’s variable valve timing system. The B18C has a 1.8-liter displacement and features a high compression ratio, making it an excellent choice for performance enthusiasts.

Key Specifications of the B18C Engine:

• Displacement: 1.8L (1797cc)
• Configuration: Inline-4
• Fuel System: Multi-Point Fuel Injection
• Max Power Output: Around 180 hp at 8,000 rpm
• Max Torque: 130 lb-ft at 7,200 rpm

One of the key reasons the B18C is celebrated is its high-revving nature and smooth power delivery. The engine’s VTEC system kicks in at higher RPMs, offering a boost in power and a more aggressive engine note. This makes the Integra SiR-G incredibly fun to drive, particularly for those who love a high-performance engine with an emphasis on revving.

5-Speed LSD Transmission: Enhancing Performance and Handling

The 5-speed LSD transmission found in the Integra SiR-G DC2 is one of the main factors that elevate its driving experience. The LSD (Limited Slip Differential) is designed to ensure that the power from the engine is evenly distributed to both front wheels, preventing wheel spin and improving traction, especially during aggressive cornering or in slippery conditions.

Key Benefits of the 5-Speed LSD Transmission:

• Improved Cornering: The LSD helps distribute torque evenly between the two front wheels, which reduces understeering and provides better handling during sharp turns.
• Smooth Power Delivery: With the 5-speed gearbox, drivers can enjoy smooth and responsive shifts, especially when engaging in spirited driving.
• Enhanced Traction: The LSD ensures that power is sent to both wheels, preventing one wheel from spinning too much and reducing the chances of losing traction in wet or dry conditions.
• Durability: The 5-speed LSD transmission is designed for high-performance, offering longevity even under aggressive driving conditions.

The combination of the B18C engine and the 5-speed LSD transmission makes the Integra SiR-G DC2 a formidable machine on both the street and the track. It offers a thrilling driving experience with excellent control and handling.
