1997 NA Miata Differential Swap: Upgrading from Open to Torsen LSD w/3.63 Gearing for 6-Speed Prep

Описание: In this video, we upgrade our 1997 NA Mazda Miata by swapping out the stock open differential (4.1 gear ratio) for a Torsen limited slip differential (3.63 gear ratio). This essential modification is a key step in prepping for our next project: installing a 6-speed transmission from a later Miata model. Learn the benefits of an LSD over an open differential, and how the new final gearing ratio impacts shifting. Stay tuned for the next video where we complete the 6-speed transmission swap!

Open Differential vs. Limited Slip Differential (LSD)
An open differential allows the wheels to rotate at different speeds, which is useful for turning. However, in low traction situations (e.g., snow, mud), power is directed to the wheel with the least resistance, often causing the car to get stuck.

A limited slip differential (LSD), like the Torsen brand, also allows for different wheel speeds but transfers power to the wheel with more traction. This results in better handling and acceleration, especially in performance driving and adverse conditions.

Benefits of an LSD
Improved Traction: Power is better distributed to the wheel with the most grip, preventing loss of traction.
Better Handling: Enhanced stability and cornering, making it ideal for spirited driving and track use.
Increased Acceleration: More effective power transfer can improve 0-60 times and overall performance.

Why Swap to an LSD?
Installing an LSD in your car enhances performance, making it better suited for both daily driving and high-performance applications. It’s especially beneficial if you're planning to increase power or take your car to the track.

Final Gearing Impact
The final gear ratio affects how "long" or "short" your gears feel:

Higher Ratio (e.g., 4.1): Shorter gears, faster acceleration, but higher RPMs at cruising speeds.
Lower Ratio (e.g., 3.63): Longer gears, slower acceleration, but lower RPMs at cruising speeds.
Switching from a 4.1 to a 3.63 ratio will make each gear "longer," meaning you can stay in each gear for a longer period, reducing the frequency of shifts and potentially improving fuel efficiency on highways.
