The Diagnostic / The Situation
Building a wild Subaru requires a deep understanding of the vehicle’s mechanics, suspension, and electrical systems. As a Master Jeep Mechanic and Off-road Engineer, I’ll provide a comprehensive guide on how to modify a Subaru for off-road adventures. The key to a successful build is identifying the right components to upgrade and understanding how they interact with each other.
Symptoms or signs to look for when building a wild Subaru include:
- Insufficient ground clearance
- Inadequate suspension travel
- Lack of power and torque
- Inadequate braking performance

Technical Deep Dive
The Subaru’s all-wheel-drive system is a significant advantage for off-road driving. However, the stock suspension and chassis may not be suitable for extreme off-road use. Common failure points include:
- The stock CV axles, which can break under heavy stress
- The stock suspension components, which can be prone to damage from rocks and other obstacles
- The engine and transmission, which may not be able to handle the increased demands of off-road driving
The Subaru’s engine and transmission are designed to provide a balance of power and efficiency. However, for off-road use, a more powerful engine and a transmission with a lower gear ratio may be necessary. The electrical system must also be modified to accommodate the increased demands of off-road driving, including the installation of auxiliary lights, winches, and other accessories.

Step-by-Step Guide
Step 1: Planning and Design
The first step in building a wild Subaru is to plan and design the build. This includes:
Step 1.1: Define the Build’s Purpose
Determine the intended use of the vehicle, including the type of terrain and the level of difficulty.
Step 1.2: Research and Gather Information
Research different modification options, including suspension lifts, engine and transmission upgrades, and electrical system modifications.
Step 1.3: Create a Budget and Timeline
Establish a budget and timeline for the build, including the cost of parts and labor.
Step 2: Suspension Upgrades
The suspension system is critical for off-road driving. Upgrades may include:
Step 2.1: Install a Suspension Lift Kit
Install a suspension lift kit to increase ground clearance and provide more suspension travel.
Step 2.2: Upgrade the Shocks and Struts
Upgrade the shocks and struts to provide better damping and control.
Step 2.3: Install CV Axles
Install CV axles to provide more strength and durability.
Step 3: Engine and Transmission Upgrades
The engine and transmission must be upgraded to provide more power and torque. Upgrades may include:
Step 3.1: Install a Performance Engine
Install a performance engine, such as a turbocharged or supercharged engine.
Step 3.2: Upgrade the Transmission
Upgrade the transmission to provide a lower gear ratio and more strength.
Step 3.3: Install a Performance Exhaust System
Install a performance exhaust system to provide more power and torque.
Step 4: Electrical System Upgrades
The electrical system must be modified to accommodate the increased demands of off-road driving. Upgrades may include:
Step 4.1: Install Auxiliary Lights
Install auxiliary lights, such as LED light bars and spotlights.
Step 4.2: Install a Winch
Install a winch to provide a means of recovery.
Step 4.3: Upgrade the Battery and Alternator
Upgrade the battery and alternator to provide more power and durability.
Pro Tips & Common Mistakes
- Don’t underestimate the importance of proper planning and design.
- Don’t skip the suspension upgrades, as they are critical for off-road driving.
- Don’t overdo it on the engine and transmission upgrades, as they can be expensive and may not provide the desired results.
- Do consider the weight and balance of the vehicle, as excessive weight can negatively impact performance.
- Do follow proper welding and electrical safety procedures.
Cost Analysis: DIY vs Mechanic
The cost of building a wild Subaru can vary widely, depending on the extent of the modifications. A DIY build can save money on labor costs, but may require more time and expertise. A mechanic build can provide more expertise and a faster turnaround time, but may be more expensive.
Frequently Asked Questions
- What is the best suspension lift kit for a Subaru? The best suspension lift kit for a Subaru depends on the intended use and the level of difficulty. A lift kit with a higher lift height and more suspension travel may be necessary for extreme off-road use.
- How much power and torque can I expect from a performance engine? The amount of power and torque from a performance engine depends on the specific engine and the level of modification. A turbocharged or supercharged engine can provide more power and torque, but may also increase the risk of engine damage.
- What is the best way to upgrade the electrical system? The best way to upgrade the electrical system is to install a high-output alternator and a deep-cycle battery. Auxiliary lights, winches, and other accessories can be installed to provide more power and functionality.
- How much does it cost to build a wild Subaru? The cost of building a wild Subaru can vary widely, depending on the extent of the modifications. A DIY build can save money on labor costs, but may require more time and expertise. A mechanic build can provide more expertise and a faster turnaround time, but may be more expensive.
- What are the most common mistakes to avoid when building a wild Subaru? The most common mistakes to avoid when building a wild Subaru include underestimating the importance of proper planning and design, skipping the suspension upgrades, and overdoing it on the engine and transmission upgrades. Following proper welding and electrical safety procedures is also critical to avoid damage and injury.
