### Pros and Cons of Buying a Mitsubishi A32B (A32-B) Engine

The Mitsubishi A32B is a naturally aspirated inline-four engine known for its reliability, simplicity, and performance in classic and modern vehicles. Below is a detailed breakdown of its advantages and disadvantages.

---

### **Pros of the Mitsubishi A32B Engine**

1. **Proven Reliability and Durability**

The A32B has a long history of use in vehicles like the Mitsubishi Lancer Evolution, Galant VR-4, and other performance-oriented models. When properly maintained, it is known for lasting well beyond 200,000 miles, especially in applications where it is not heavily modified. Its robust construction and straightforward design contribute to its longevity.

2. **Simple and Cost-Effective Maintenance**

The A32B is a relatively simple engine compared to modern turbocharged or complex fuel-injected engines. This simplicity translates to lower maintenance costs. Common services like oil changes, valve adjustments (in older models), and basic tune-ups are straightforward and inexpensive. Parts are also widely available, especially for aftermarket upgrades.

3. **Strong Naturally Aspirated Performance**

As a naturally aspirated engine, the A32B produces a satisfying linear power band without the complexity of forced induction. In stock form, it delivers around 160 180 horsepower, which is adequate for spirited driving in lighter vehicles. With minor modifications (such as a cold air intake, performance camshaft, or upgraded exhaust), it can produce noticeable power gains without the need for expensive turbocharger systems.

4. **Compatibility with Aftermarket Support**

The A32B has a large aftermarket community, particularly in the tuning and drifting scenes. This means there are numerous performance parts available, including:

- **Intake and exhaust systems** (e.g., K&N, Borla, or MagnaFlow)

- **Performance camshafts** (e.g., from Mitsubishi Performance or aftermarket brands like JE)

- **Upgraded ignition systems** (e.g., MSD or AEM distributors or coil-on-plug upgrades)

- **Tuning solutions** (e.g., Haltech, Link, or standalone ECU options)

This support makes it easier to enhance performance without a complete engine rebuild.

5. **Good for Drifting and Manual Driving**

The A32B s naturally aspirated nature and strong low-end torque make it well-suited for drifting and manual driving. Its ability to rev enthusiastically and produce a satisfying exhaust note contributes to its popularity in these applications.

6. **Fuel Efficiency (Compared to Turbocharged Alternatives)**

While not the most efficient engine in the world, the A32B offers better fuel economy than many turbocharged engines when running stock or with mild modifications. In a well-tuned condition, it can achieve around 20 25 miles per gallon in a typical sedan, which is reasonable for its power output.

7. **Ease of Modification for Beginners**

For those new to engine tuning, the A32B is an accessible platform. Modifications like swapping in a performance camshaft or upgrading the exhaust are relatively beginner-friendly compared to more complex engines like turbocharged units or those with direct injection.

8. **Resale Value in Classic and Tuner Communities**

Vehicles equipped with the A32B, particularly older models like the Lancer Evolution or Galant VR-4, hold value in niche markets. The engine s reputation for reliability and performance ensures that parts and whole engines remain in demand, which can be beneficial if you decide to sell later.

### **Cons of the Mitsubishi A32B Engine**

1. **Potential for Overheating**

The A32B is known to run hot, especially in high-performance applications or under heavy loads. This can lead to issues like warped heads, blown head gaskets, or even engine failure if not properly cooled. Upgrading to a larger radiator, improved cooling fans, or a thermostat housing can mitigate this, but it requires attention to detail.

2. **Head Gasket Failures**

One of the most common issues with the A32B is head gasket failure, particularly in older models or those with high mileage. This can occur due to overheating, poor maintenance, or simply the age of the engine. Symptoms include white smoke from the exhaust, coolant in the oil, or a loss of compression. Replacing head gaskets is a labor-intensive job that requires removing the engine from the vehicle, making it costly.

3. **Weakness in High-Performance Applications**

While the A32B can handle mild modifications, it is not designed for extreme power levels. Pushing it too hard (e.g., with aggressive turbocharging or forced induction) can lead to catastrophic failure, including blown pistons, rod bearings, or crankshaft damage. The stock bottom end is not as robust as some modern engines, so upgrading to aftermarket parts (e.g., forged internals) is often necessary for serious power gains.

4. **Valvetrain Wear in Older Models**

Early versions of the A32B (pre-1990s) had valvetrain issues, including worn camshaft lobes or lifters, which could cause knocking or valve float at high RPMs. Later models improved on this, but even newer A32Bs can develop valvetrain wear if not maintained properly. Regular valve adjustments (in manual systems) or inspections are recommended.

5. **Electrical and Fuel System Quirks**

The A32B s fuel and ignition systems can be finicky, especially in older models. Issues like faulty distributors, weak injectors, or vacuum leaks can lead to rough idling, stalling, or poor performance. Upgrading to modern ignition components or fuel injectors may be necessary for optimal tuning.

6. **Limited Modern Compatibility**

While the A32B is still used in modern builds (e.g., in drift cars or classic restorations), it is not as commonly found in contemporary vehicles as some other engines. This means that finding a compatible vehicle with a well-maintained A32B may require more effort, especially if you re looking for a project car.

7. **Noise and Vibration**

The A32B can be noisy, particularly at higher RPMs, due to its naturally aspirated design and lack of modern sound insulation. Vibration can also be an issue, especially in lighter vehicles, which may require suspension or engine mounts to be addressed.

8. **Environmental and Emissions Concerns**

The A32B is not designed to meet modern emissions standards, which can be a drawback if you plan to use the vehicle on the road frequently. Modifications like catalytic converter deletions or tuning for emissions compliance may be necessary, depending on local regulations.

9. **Limited Stock Performance in Some Applications**

In heavier vehicles or those with poor aerodynamics, the stock A32B may feel underpowered. While it can be upgraded, this requires additional investment in parts and labor.

10. **Learning Curve for Advanced Modifications**

While simple modifications are straightforward, more advanced tuning (e.g., forced induction, ECU remapping) can be complex and requires a good understanding of engine mechanics. Mistakes can lead to costly damage, so it s important to research thoroughly or consult experienced tuners.

---

### **Conclusion**

The Mitsubishi A32B engine is a fantastic choice for enthusiasts who value reliability, simplicity, and the joy of driving a naturally aspirated engine. It excels in applications like drifting, classic car restorations, and mild performance tuning, where its strengths durability, ease of modification, and strong low-end torque are fully utilized.

However, it is not without its drawbacks. Issues like overheating, head gasket failures, and valvetrain wear require vigilant maintenance and, in some cases, costly repairs. The engine s limitations in high-performance applications and its lack of modern emissions compliance also need to be considered.

For the right owner the one who is willing to invest time in maintenance and understands the engine s quirks the A32B is an incredibly rewarding platform. It offers a balance of performance, modifiability, and longevity that is hard to match in naturally aspirated engines of its era.
