Whether restoring a classic BMW to its original glory or upgrading an existing electrical system for improved performance, this harness delivers precision engineering and long-term durability, making it a trusted choice for both enthusiasts and professional mechanics. Its compatibility with a wide range of BMW models ensures versatility, while its meticulous construction guarantees a reliable foundation for any electrical modification or repair project.
### **Pros and Cons of Buying a BMW 320i (E30, 1987 1994) with a 3.0L M50B20 Engine and A8A Transmission (914 Harness)**
#### **Overview**
The BMW 320i (E30) with the **3.0L M50B20 inline-6 engine** and **A8A 5-speed manual transmission** (paired with a **914 harness**, a common aftermarket upgrade for better shift quality) is a classic BMW with a strong reputation for reliability, driving dynamics, and aftermarket support. However, like any vehicle from this era, it comes with trade-offs. Below is a detailed breakdown of its advantages and disadvantages.
---
### **Pros**
1. **Engine Performance and Reliability**
- The **M50B20** is one of BMW s most durable inline-6 engines, known for its smooth power delivery (170 hp, 177 lb-ft torque) and longevity when maintained properly.
- With proper care, many M50 engines easily exceed **200,000 miles**, especially in European markets where they were built for harsh conditions.
- The engine s **pushrod design** (unlike later fuel-injected M50s) means it s simpler to work on, with fewer electronic failures compared to later BMW engines.
2. **Driving Dynamics and Handling**
- The **E30 chassis** is one of BMW s most balanced, offering a perfect blend of sportiness and comfort.
- The **A8A 5-speed manual transmission** (when properly tuned) provides crisp, engaging shifts especially with a **914 harness**, which reduces clutch drag and improves shift quality.
- The **rear-wheel-drive layout** and **MacPherson strut front suspension** (with adjustable dampers in some models) make it highly responsive and fun to drive.
- The **steering feel** is precise, and the car handles well on both road and track (though not as agile as later E46 M3s).
3. **Aftermarket Support and Customization**
- The **E30 platform** has been around for decades, meaning **parts, modifications, and tuning options are abundant**.
- The **914 harness** (a common aftermarket upgrade) improves shift quality by reducing clutch drag and allowing for smoother, more precise gear changes.
- **Engine upgrades** (turbocharging, supercharging, or even swapping in a **S50B25** from an E36 M3) are well-documented and achievable.
- **Suspension upgrades** (coilovers, sway bars, lower springs) can significantly improve handling.
- **Exhaust and intake modifications** are straightforward, allowing for noticeable power gains without major engine work.
4. **Fuel Efficiency and Practicality**
- The **M50B20** is relatively efficient for its power output, averaging **20 25 MPG** in real-world driving (better than many modern sedans of similar power).
- The **E30 s interior** is spacious for a coupe, with a **comfortable ride** and **good visibility**.
- The **trunk (12.5 cu ft)** is small but adequate for daily use, though not as large as modern sedans.
5. **Classic BMW Appeal and Community**
- The **E30 320i** is a **beloved classic**, with a strong owner community, clubs, and events (e.g., BMW E30 Club, Concours d Elegance).
- The car holds **good value** in the classic market, especially well-maintained examples.
- Its **timeless design** (with optional **M3 styling**) makes it a desirable car for enthusiasts.
6. **Simplicity and Durability (Compared to Later BMWs)**
- Unlike later BMWs with **complex electronics**, the **E30 s mechanical systems** (clutch, transmission, suspension) are **easier to diagnose and repair**.
- The **A8A transmission** is a **simple, robust manual gearbox** (though clutch wear is a common issue).
- **No major electronic failures** (unlike later BMWs with DME issues, ABS failures, or airbag problems).
---
### **Cons**
1. **Clutch and Transmission Wear**
- The **A8A transmission** is **notoriously weak on the clutch**, especially in modern driving conditions (short trips, stop-and-go traffic).
- **Clutch replacements** are frequent (every **30,000 50,000 miles** in heavy use) and can be **expensive** if done professionally.
- The **914 harness helps**, but it doesn t eliminate the need for clutch maintenance.
- **Synchronizers** in the transmission can also wear out over time, requiring **gear replacement** (a costly repair).
2. **Rust and Bodywork Issues**
- The **E30 is prone to rust**, particularly in the **wheel arches, sills, and rear quarter panels**.
- **Original paint and clear coat** degrade over time, leading to **peeling or faded finishes**.
- **Roof rust** is common in older examples, especially if stored outdoors.
- **Corrosion checks** (especially in the **floor pans and subframe**) are **essential** before purchasing.
3. **Electrical and Interior Wear**
- The **interior** (especially in higher-mileage examples) can be **worn out**, with **cracked dash, faded upholstery, and failing electronics**.
- **Original wiring harnesses** (including the **914 harness**) can degrade over time, leading to **intermittent electrical issues**.
- **Heater and A/C systems** can fail, requiring **expensive rebuilds**.
- **Power window regulators** and **door locks** are common failure points.
4. **Maintenance and Repair Costs**
- While **mechanical repairs** (engine, suspension, drivetrain) are **less complex** than later BMWs, **parts can be expensive**.
- **Specialty tools** (e.g., BMW-specific torque wrenches, diagnostic equipment) are often required.
- **Labor costs** can add up, especially for **rust repairs, electrical work, or transmission rebuilds**.
- **Insurance costs** are typically **higher** than for modern cars due to **specialty parts and repair complexity**.
5. **Comfort and Modern Amenities**
- The **E30 lacks modern safety features** (no ABS, no airbags in early models, no stability control).
- **Heating and A/C performance** can be **inconsistent**, especially in cold climates.
- **Noise insulation** is **poor** compared to modern cars, leading to **wind and road noise**.
- **No power steering** (though the **recirculating ball steering** is precise, it requires more effort than modern power-assisted systems).
- **No cruise control** in base models (though aftermarket options exist).
6. **Fuel and Emissions Compliance**
- The **M50B20 is not emissions-compliant** in many regions (e.g., California, EU with modern standards).
- **Smog checks** (if required) can be **difficult or impossible** without modifications (e.g., **catalytic converter swaps**).
- **Insurance may be harder to obtain** in areas with strict emissions laws.
7. **Depreciation and Long-Term Ownership Costs**
- While the **E30 retains value well**, **ongoing maintenance costs** (clutch, suspension, electrical) can **add up over time**.
- **Replacement parts** (e.g., **A8A transmission components, M50 engine parts**) can be **expensive** if not sourced from specialty suppliers.
- **Storage and transport** (if kept in a climate-controlled environment) can be **costly** compared to modern cars.
8. **Limited Modern Safety Features**
- **No modern safety ratings** (NHTSA, Euro NCAP) apply, making it **less safe in a collision** compared to modern vehicles.
- **No side-impact protection** in early models (though later E30s had some improvements).
- **No advanced driver aids** (blind-spot monitoring, lane-keeping, etc.).

### **Conclusion**
The **BMW E30 320i with an M50B20 engine and A8A transmission (paired with a 914 harness)** is a **fantastic choice for enthusiasts** who appreciate **classic BMW driving dynamics, aftermarket potential, and mechanical simplicity**. It offers **strong performance, reliability (when maintained), and a strong owner community**, making it ideal for **weekend drivers, track enthusiasts, and those who enjoy working on their cars**.
