If you’re a Volkswagen enthusiast, chances are you’ve dreamt of building a high-performance VW that offers the perfect blend of power, reliability, and a unique driving experience. One of the most exciting ways to achieve this is by combining the classic VW styling and engineering with the advanced, performance-driven components of a Subaru drivetrain.
Subaru’s innovative engineering, especially in their engines and transmissions, has made them a popular choice for those looking to upgrade or convert their VW vehicles. In this blog, we’ll explore how to build a high-performance VW using Subaru drivetrain parts, focusing on the benefits, key components, and tips to get the best results.
The Benefits Of Using Subaru Drivetrain Parts In A VW Build
When it comes to performance upgrades, using Subaru drivetrain parts in a VW build offers several advantages:
- Enhanced Power and Performance: Subaru’s engines, especially the EJ and FB series, are known for their robust power output and torque. Coupling a Subaru drivetrain with a VW chassis can give your vehicle a significant performance boost without compromising reliability.
- Advanced All-Wheel Drive Capabilities: Subaru’s symmetrical all-wheel-drive (AWD) systems are renowned for their handling and traction, making them an ideal choice for those looking to enhance their VW’s handling in various road conditions.
- Reliability and Durability: Subaru engines and transmissions are designed for longevity, with a reputation for being able to handle significant power and stress. This is particularly advantageous for those looking to create a vehicle capable of withstanding intense driving conditions.
- Aftermarket Support: Subaru’s popularity in motorsports and the aftermarket world means that you can find a wealth of parts and resources to fine-tune and customize your build. Whether it’s for engine tuning, suspension upgrades, or drivetrain components, there’s a large pool of aftermarket parts and expertise available.
Key Subaru Drivetrain Components For Your VW Build
Building a high-performance VW with a Subaru drivetrain requires careful selection of parts. Below, we explore some of the key components that will take your VW build to the next level.
1. Subaru EJ Engine
The Subaru EJ engine series, which includes the EJ20, EJ22, EJ25, and more, is a popular choice for engine swaps into various vehicles, including VW models. Known for its durability, efficiency, and high-revving nature, the EJ engine provides plenty of power for a variety of performance builds.
- Benefits of the EJ Engine: The EJ engine offers a balance of high torque at low RPMs and the ability to handle high boost pressure, making it ideal for turbocharging. It’s capable of producing impressive horsepower numbers while maintaining fuel efficiency compared to some other performance engines.
- Installation Considerations: When swapping an EJ engine into a VW, you’ll need custom motor mounts and potentially modifications to the engine bay to fit the engine properly. It’s also essential to choose the right transmission to match the engine’s power and torque output.
2. High-Capacity Oil Pan For Subaru Engines
One of the essential upgrades when building a high-performance VW with Subaru drivetrain parts is a high-capacity oil pan. A high-capacity oil pan increases the engine’s oil volume, providing better lubrication during high-performance driving and reducing the risk of oil starvation under extreme conditions.
- Why It’s Important: When you’re pushing an engine to its limits, oil starvation can cause severe damage to the engine. A larger oil pan ensures that the engine has a steady supply of oil, even under high-G cornering or heavy acceleration, helping to maintain consistent engine performance.
- Product Recommendation: The high-capacity oil pan from Specialised Parts is specifically designed for Subaru engine swaps, providing optimal performance and durability.
3. Subaru Rear Differential
The rear differential is another crucial component when building a high-performance VW with Subaru parts. Subaru’s rear differentials, especially those found in the WRX and STI models, are built to handle the power generated by their turbocharged engines, making them an excellent option for performance-focused builds.
- Why the Subaru Rear Differential? These differentials offer strength, reliability, and excellent power distribution, making them ideal for driving conditions that require heavy torque handling. Additionally, they allow for customization with various gear ratios, giving you the ability to fine-tune the performance of your build.
- All-Wheel Drive Considerations: If you’re incorporating an all-wheel-drive (AWD) system, the Subaru rear differential is crucial in achieving balanced power delivery to all four wheels. This setup improves traction, handling, and stability, particularly when cornering at high speeds.
Other Performance Parts To Consider For Your VW-Subaru Build
While the drivetrain is central to the build, there are other performance components you should consider to ensure that your high-performance VW performs optimally.
Suspension Upgrades
When you’re increasing engine power and improving handling, suspension upgrades are essential. Subaru’s suspension components are known for their reliability and performance, especially in models like the WRX and STI. These components can be adapted for your VW build, providing improved handling, ride quality, and stability at higher speeds.
Braking System
Upgrading the braking system is crucial when building a high-performance vehicle. Subaru’s high-performance braking systems, found on models like the WRX STI, offer excellent stopping power, especially under extreme driving conditions. Upgrading to Subaru’s performance brakes will allow you to safely handle the increased speeds and performance that come with a Subaru drivetrain.
Exhaust System
An upgraded exhaust system will enhance your engine’s breathing, allowing it to operate more efficiently and produce more power. The Subaru WRX STI exhaust system, for example, is known for its robust sound and high flow, making it a great option for high-performance builds.
Tips For A Successful VW-Subaru Drivetrain Build
Building a high-performance VW with Subaru drivetrain parts is a challenging yet rewarding endeavour. To ensure a successful build, here are some tips to keep in mind:
- Plan and Research Thoroughly: Understand the compatibility of the parts you plan to use, as not all Subaru components are directly interchangeable with VW models. Proper planning will help prevent costly mistakes and unnecessary modifications.
- Choose the Right Transmission: The right transmission will ensure that your engine performs optimally. Subaru’s 5-speed and 6-speed transmissions are solid choices, but be sure to choose one that matches the power output of your engine.
- Engine Management: Proper engine management is crucial when swapping a Subaru engine into a VW. Make sure to invest in a quality engine control unit (ECU) and tune it for the specific combination of parts you’re using. This will maximize performance and fuel efficiency.
- Use Quality Aftermarket Parts: While OEM parts are great, performance-focused aftermarket parts will give your VW build the edge it needs. Look for components designed for high-performance applications to ensure longevity and durability.
