The Nissan R33 GT-R is a legendary sports car known for its performance and handling capabilities. To further enhance its prowess on the road and track, many enthusiasts consider upgrading key components such as limited slip differentials and bushings. In this article, we will explore the benefits of these upgrades and provide a step-by-step guide on how to install them.
Understanding Limited Slip Differentials
A limited slip differential (LSD) is a crucial component that helps to distribute power between the wheels, improving traction and stability. Unlike an open differential, which allows one wheel to spin freely, an LSD ensures that both wheels on the axle receive power, enhancing cornering ability and reducing tire wear.
- Improved traction during acceleration
- Better cornering stability
- Reduced tire wear
Types of Limited Slip Differentials
There are several types of limited slip differentials available for the R33 GT-R, each with its own advantages.
- Clutch-type LSD: Uses clutch plates to limit slip and is known for its responsiveness.
- Gear-type LSD: Utilizes gears to provide a more gradual engagement, suitable for street applications.
- Viscous LSD: Employs a viscous fluid to transfer torque, offering smooth operation.
Benefits of Upgraded Bushings
Upgrading the bushings in your R33 GT-R can significantly improve handling and ride quality. Stock bushings tend to wear out over time, leading to a loss of precision in steering and suspension response.
- Enhanced steering response
- Improved suspension geometry
- Reduced vibrations and noise
Choosing the Right Bushings
When selecting bushings for your R33 GT-R, consider the following options:
- Polyurethane Bushings: Offer a balance between comfort and performance, providing better durability than rubber.
- Solid Bushings: Provide the most direct connection between components but may increase noise and vibrations.
Installation of Limited Slip Differentials
Installing a limited slip differential in your R33 GT-R can be a complex task, but with the right tools and guidance, it can be accomplished effectively.
Tools Required
- Jack and jack stands
- Socket and wrench set
- Differential fluid
- Torque wrench
Step-by-Step Installation Process
- Start by lifting the vehicle and securing it on jack stands.
- Remove the rear wheels and disconnect the driveshaft from the differential.
- Unbolt the differential cover and drain the fluid.
- Remove the old differential and replace it with the new limited slip differential.
- Reassemble the components in reverse order, ensuring all bolts are torqued to specifications.
- Refill the differential with new fluid and check for leaks.
Installation of Upgraded Bushings
Replacing the bushings in your R33 GT-R is another essential upgrade that can enhance handling and performance.
Tools Required
- Jack and jack stands
- Socket and wrench set
- Press tool or bushing removal tool
- Grease for installation
Step-by-Step Installation Process
- Lift the vehicle and secure it on jack stands.
- Remove the wheels and lower control arms as necessary to access the bushings.
- Use a bushing removal tool to extract the old bushings.
- Apply grease to the new bushings and press them into place.
- Reassemble the suspension components and ensure everything is torqued to specifications.
Conclusion
Upgrading the limited slip differential and bushings in your R33 GT-R can significantly improve its handling and performance. With the right tools and a bit of mechanical knowledge, these upgrades can be performed at home, providing you with a more responsive and enjoyable driving experience. Whether you’re on the track or the street, these modifications will help you get the most out of your iconic Nissan GT-R.
