Transforming a vehicle’s drivetrain can unlock new levels of performance and handling—especially for mid-engine applications.
For automotive enthusiasts and mechanics working on custom builds, converting a Subaru transmission from an All-Wheel Drive (AWD) to a Two-Wheel Drive (2WD) opens exciting possibilities.
One of the most efficient ways to achieve this is by using the Subaru 5EAT 2WD Conversion Kit.
This comprehensive blog dives deep into why this conversion kit is essential for mid-engine applications, what benefits it offers, and how it functions.
What Is the Subaru 5EAT 2WD Conversion Kit?
The Subaru 5EAT 2WD Conversion Kit is designed specifically for the 5-speed microprocessor-controlled automatic transmissions found in Subaru vehicles.
This kit effectively converts the transmission from AWD to 2WD, making it ideal for custom mid-engine configurations where full-time AWD isn’t necessary or desired.
Here’s what makes this conversion kit indispensable for specific automotive projects:
- Same rotation as the original output axles – Ensures consistent power delivery.
- Precision-engineered components – Built for reliability and performance.
What’s Included In The Kit?
When you purchase the conversion kit, you receive:
- Large back cover plate with mounting holes
- Output shaft
- Output gear
- Mounting bracket with bolts
- Thrust bearing retaining ring plate
- Pair of Subaru OEM stub axle shafts
- Pair of 100 mm standard-length axle flanges
Each component is engineered for a seamless transition from AWD to 2WD, ensuring durability and optimal performance in mid-engine applications.
Why Use A 2WD Conversion Kit For Mid-Engine Builds?
Mid-engine configurations have become increasingly popular, especially in custom builds, kit cars, and replica cars. By repositioning the engine towards the center of the vehicle, weight distribution improves dramatically, enhancing balance and handling.
However, using an AWD transmission in a mid-engine setup can lead to unnecessary complications. This is where the Subaru 5EAT 2WD conversion kit becomes a game-changer.
Advantages Of Switching To 2WD For Mid-Engine Applications
- Weight Reduction: Removing the AWD components reduces overall vehicle weight.
- Simplified Drivetrain: A 2WD system eliminates the need for extra drivetrain components.
- Improved Handling: Ideal weight distribution boosts cornering and handling.
- Enhanced Performance: Reduced drivetrain drag can improve acceleration and speed.
How Does The Subaru 5EAT Transmission Work?
Before diving deeper into the conversion process, it’s important to understand how the Subaru 5EAT automatic transmission functions.
This 5-speed automatic transmission uses a microprocessor-controlled system that adjusts shifting patterns based on driving conditions. Common in Subaru models like the Outback and Legacy, the 5EAT offers seamless shifting, durability, and reliability.
The 5EAT’s original AWD system sends power to all four wheels, maximizing traction. However, for custom builds, especially those with mid-engine layouts, AWD may not always be necessary.
Benefits Of Converting Subaru’s AWD To 2WD
- Reduced Mechanical Complexity: Simplifies the drivetrain layout.
- Optimized Power Delivery: Delivers all engine power to two wheels, ideal for certain races or custom builds.
- Enhanced Fuel Efficiency: Less energy loss compared to AWD systems.
Installing The Subaru 5EAT 2WD Conversion Kit
Converting a Subaru 5EAT transmission from AWD to 2WD is a specialized task that requires mechanical expertise. Below is an overview of the process.
Step 1: Prepare Your Tools And Workspace
Before starting the installation, ensure you have:
- A clean, well-lit workspace
- Torque wrench
- Socket set
- Screwdrivers
- Lubricants and sealants
Step 2: Remove The AWD Components
- Disassemble the rear section of the transmission.
- Carefully remove AWD components, including the centre differential and driveshaft.
Step 3: Install The Conversion Kit Components
- Attach the large back cover plate using the provided bolts.
- Insert the new output shaft and gear into place.
- Install the thrust bearing retaining ring plate.
- Mount the stub axle shafts and axle flanges securely.
Step 4: Testing The Transmission
Once installed, run diagnostic tests to ensure:
- Proper gear engagement
- Smooth output shaft rotation
- Secure flange mounting
It’s advisable to consult a professional mechanic if any issues arise during installation.
Tips For Maintaining Your 5EAT 2WD Transmission
After installation, keeping your converted transmission in peak condition is crucial. Here are some maintenance tips:
Regular Fluid Checks
Transmission fluid should be checked every 5,000 to 10,000 km. Clean fluid ensures smooth operation.
Monitor For Leaks
Inspect seals and gaskets regularly. Early detection can prevent major repairs.
Professional Inspections
Have a professional inspect your drivetrain annually. They can identify wear before it becomes an issue.
