Buy B18C 1998-2001 HONDA ACURA INTEGRA DC2 B18 TYPE R 5 SPEED LSD SWAP for sale online, The 1998-2001 Honda Acura Integra DC2 B18 Type R is one of the most iconic and highly regarded sports cars of its time. Known for its impressive performance and precision handling, the Integra Type R has become a favorite among car enthusiasts and tuners. One of the most sought-after upgrades for this car is the 5-Speed Limited Slip Differential (LSD) swap, particularly with the B18C engine. This guide delves into what the swap involves, why it’s a popular upgrade, and answers frequently asked questions related to the process.

What is the B18C Engine?

The B18C is a 1.8L DOHC (Dual Overhead Cam) engine that was produced by Honda as part of its B-series family. It was featured in several models, including the 1998-2001 Acura Integra Type R, where it was paired with a high-performance gearbox and other race-inspired components. The engine produces around 190 horsepower and 130 lb-ft of torque, making it an excellent choice for drivers who crave power and responsiveness.

Why the 5-Speed LSD Swap?

The 5-speed LSD swap is one of the most popular upgrades for the Integra Type R. The limited-slip differential is a crucial component of the vehicle’s drivetrain, designed to optimize traction between the left and right wheels on the same axle. The B18C engine is known for its rev-happy characteristics and its ability to produce high amounts of power at higher RPMs. A 5-speed LSD-equipped transmission helps transfer that power more effectively to the road, improving acceleration, cornering, and overall performance.

Here are a few reasons why car enthusiasts opt for this upgrade:

1. Improved Traction: The LSD helps to distribute power more evenly between the two front wheels, preventing the loss of power during hard cornering or acceleration, which is especially useful in motorsports or spirited driving.

2. Better Cornering Control: An LSD helps the car maintain a higher level of control when taking tight corners, reducing understeer or oversteer during aggressive driving.

3. Increased Performance: A 5-speed LSD swap allows the car to handle power more efficiently, offering better acceleration and performance in both track and street conditions.

4. Durability: A high-quality LSD-equipped transmission is generally more robust and durable, making it a popular choice for drivers who track their cars or want a more reliable setup for daily driving.

The Swap Process

Swapping a B18C 5-Speed LSD transmission into a 1998-2001 Honda Acura Integra DC2 Type R involves several important steps. Here’s an overview of the process:

1. Preparation: Start by gathering all the necessary parts and tools for the swap. This includes the 5-speed LSD transmission, matching axles, shift linkage, clutch assembly, and other related components. It’s also essential to have the right tools for removing the existing transmission and installing the new one.

2. Removing the Existing Transmission: Begin by removing the old transmission, which requires draining the transmission fluid, disconnecting the shift linkage, and unbolting the transmission from the engine.

3. Installing the LSD Transmission: Once the old transmission is removed, carefully install the new 5-speed LSD transmission. Be sure to align it properly with the engine and secure all bolts and fasteners. The LSD-equipped transmission should mate seamlessly with the B18C engine.

4. Connecting the Shift Linkage: The shift linkage will need to be adjusted to fit the new transmission. Be sure to align it properly to ensure smooth shifting.

5. Installing New Components: If necessary, replace the clutch and flywheel to ensure proper engagement with the new transmission. New axles may also be required to match the LSD setup.

6. Testing and Tuning: Once the swap is complete, test the car to ensure that the LSD functions properly and that the car shifts smoothly. It’s essential to perform a test drive to check for any issues before hitting the road.

Key Considerations Before Starting the Swap

• Skill Level: This swap is not for beginners. It requires advanced mechanical knowledge and the ability to work on the car’s drivetrain. If you’re not comfortable with performing such an upgrade, it’s recommended to seek professional help from a mechanic or tuner.

• Parts Compatibility: While the swap is generally straightforward for those who have experience with the B18C engine and the 5-speed LSD transmission, it’s crucial to verify that all parts are compatible with your specific model and year of Integra.

• Cost: The cost of the swap can vary depending on the quality of parts used, the labor involved, and whether you choose to buy new or used components. It’s important to budget accordingly and be prepared for potential additional costs.

• Legal and Emissions Compliance: Depending on your location, the swap may require compliance with local emissions laws or safety regulations. Ensure that the swap meets the required standards before completing the process.
