### Pros and Cons of Buying a 2001 2004 Ford Mustang with a 5.0L (Performance) or 4.6L (78264) Engine and a 78264 Fuel Tank

#### **Pros**

1. **Classic Mustang Design** The 2001 2004 Mustang retains the iconic 1994 1998 SN-95 styling with a bold, aggressive front end, making it instantly recognizable and desirable for enthusiasts.

2. **Strong Engine Options**

- **5.0L (Performance) Engine (FOX or 78264)** The 5.0L V8 (especially the 78264 variant) is a proven, high-performance engine with good reliability if well-maintained. It produces **225 240 hp** and **280 290 lb-ft of torque**, making it capable of handling performance modifications.

- **4.6L (78264) Engine** While less powerful than the 5.0L (around **210 hp**), it is smoother and more refined, with a lower risk of common 5.0L issues like valve cover leaks or oil consumption.

- **Intake & Exhaust** Aftermarket intakes, headers, and exhaust systems can improve airflow and sound.

- **ECU Tuning** Software tweaks (via **Ford Tuning, Haltech, or Link**) can unlock extra horsepower.

- **Forced Induction** Superchargers (like **Eaton M90**) or turbochargers can significantly boost power, though the 4.6L is more turbo-friendly due to its lower compression ratio.

4. **Strong Aftermarket Support** Parts, forums (like **MustangForums, MustangPower, or 911Forums**), and tuners are widely available, making maintenance and modifications easier.

5. **Good Driving Dynamics** The **FOX 5-link rear suspension** (on 2001 2004 models) provides a sporty, engaging ride, especially when upgraded with coilovers or sway bars.

6. **Potential for High Value** Well-maintained examples, especially with low miles and proper modifications, can appreciate in value, particularly if kept in original condition or restored.

7. **Durability of the 78264 Fuel Tank** The **78264 fuel tank** (used in 2003 2004 Mustangs) is a **steel tank with a fuel pump module**, which is more durable than the plastic tanks in some later models. However, it is still prone to rust and leaks if not properly maintained.

8. **Classic Mustang Culture** Owning a 2001 2004 Mustang places you in a strong community of enthusiasts, with events, meets, and a shared passion for the car s heritage.

#### **Cons**

1. **Common Engine Issues**

- **Oil consumption** (especially in high-mileage examples).

- **Valve cover leaks** (common due to gasket failure).

- **Rod bearing wear** (if not properly maintained).

- **Camshaft wear** (can lead to excessive oil consumption).

- **Head gasket failures** (less common but possible with overheating).

- **Oil leaks** (valve cover, oil filter housing gasket).

- **Less torque** compared to the 5.0L, which can make it feel less powerful in stock form.

2. **Fuel Tank Reliability**

- **Rust and corrosion** (especially in snowy or salted regions).

- **Leaks at welds or the fuel pump module**.

- **Difficulty in replacement** (requires removing the rear seat and floor mats).

- Some owners report **fuel pump failures** over time, requiring replacement.

3. **Transmission & Drivetrain Weaknesses**

- **4R70W 4-Speed Automatic** While durable, it can develop **slippage, rough shifting, or solenoid failures** if not maintained.

- **Torsen Limited-Slip Differential (LSD)** The **Torsen 3020** is strong but can wear out over time, leading to **whining or reduced lock-up**.

- **Clutch (Manual Models)** If buying a **manual (5-speed)**, expect **clutch wear** over time, especially if the car has high mileage.

4. **Suspension & Handling Wear**

- **Shocks & Struts** The stock **FOX shocks** wear out quickly, leading to a **soft, bottoming-out ride**.

- **Control Arms & Bushings** The **5-link rear suspension** can develop **looseness or binding** over time.

- **Steering Rack** Some models develop **play or leaks** in the steering rack.

5. **Electrical & Interior Issues**

- **Faulty Window Regulators** Common in older Mustangs, leading to **sticky or non-functional windows**.

- **Infotainment & Electronics** The **stock radio and climate controls** can be unreliable, and aftermarket upgrades are often necessary.

- **Power Steering Pump** Some 2001 2004 models have **leaking or failing power steering pumps**, requiring replacement.

6. **Rust Concerns**

- While not as severe as some other Mustangs (e.g., 1990s models), **rocks, road salt, and poor maintenance** can lead to **frame rust, wheel wells, and undercarriage corrosion**.

7. **Fuel Economy**

- The **5.0L and 4.6L engines are thirsty**, averaging **12 15 MPG in the city and 18 22 MPG on the highway**, making them expensive to run.

8. **Depreciation & Market Saturation**

- The **2001 2004 Mustang market is saturated**, meaning **prices are often high for average examples**, and finding a **well-documented, low-mileage car** can be difficult.

- **Restomod Mustangs** (modified but kept in original shell) can be pricey, while **project cars** may require significant investment.

9. **Recall & Safety Issues**

- Some models have **unresolved recalls** (e.g., **airbag, seatbelt, or fuel system issues**), so always check **NHTSA and Carfax reports**.

- **Rear visibility** is poor due to the **large rear window and small side mirrors**.

10. **Modification Costs**

- While tunable, **serious modifications (supercharger, turbo, suspension upgrades)** can be **expensive**, especially if done poorly.

---

### **Conclusion**

The **2001 2004 Ford Mustang with a 5.0L (Performance) or 4.6L (78264) engine and a 78264 fuel tank** is a **great choice for enthusiasts** who appreciate **classic styling, mod potential, and a strong community**.
