### **Pros and Cons of Buying a Mitsubishi AJ55TB3-16D (AJ55TB316D) Engine**

The **Mitsubishi AJ55TB3-16D** is a 5.0-liter (5,018 cc) V8 engine originally developed for the **Mitsubishi Eclipse GT** and later used in various performance and luxury vehicles, including the **Dodge Viper (early models), Mitsubishi 3000GT, and some aftermarket applications**. Below is a detailed breakdown of its advantages and disadvantages.

---

### **Pros of the AJ55TB3-16D**

1. **High Performance Potential**

- The AJ55TB3 is a **naturally aspirated (NA) V8** designed for high RPM performance, with a **redline of 7,000 RPM** in stock form.

- It produces **around 300 320 hp (depending on tuning and application)** in stock form, making it strong for its displacement.

- With **aftermarket tuning (intake, exhaust, ECU remap, and forced induction)**, it can easily exceed **500 hp** while maintaining reliability if properly maintained.

2. **Durability and Longevity**

- The AJ55TB3 is built on a **cast-iron block** with **wet sump lubrication**, which is robust and less prone to oil leaks compared to some aluminum-block engines.

- The **pushrod OHV design** is simpler and more forgiving than modern DOHC engines, making it easier to modify and repair.

- Many examples have **exceeded 200,000 miles** with proper maintenance, especially in **high-performance applications** where engines are often rebuilt rather than scrapped.

3. **Aftermarket Support and Modification Potential**

- The AJ55TB3 has a **strong aftermarket**, with widely available parts for **turbocharging, supercharging, and nitrous oxide (N2O) setups**.

- **Turbocharging** (with proper intercooling) can push power to **600 800 hp** with a well-built setup.

- **Supercharging** (e.g., Eaton M90) is also popular, offering **400 600 hp** with stock bottom end.

- **Nitrous oxide** is a cost-effective way to add **100 200 hp** without major engine stress.

- **Fuel injection upgrades** (e.g., **Megajet, Haltech, or standalone ECUs**) are widely supported for precise tuning.

4. **Reliability in Stock Form (When Properly Maintained)**

- If **oil changes are done every 3,000 5,000 miles (with high-quality synthetic oil like Mobil 1 or Pennzoil Platinum)**, the AJ55TB3 can last **100,000 miles** without major issues.

- **Common weak points** (like valve springs and lifters) can be upgraded cheaply, extending engine life further.

- **Less prone to catastrophic failure** compared to some modern engines due to its **mechanical simplicity**.

5. **Affordability Compared to Modern High-Performance Engines**

- **Used AJ55TB3 engines** can be found for **$1,500 $3,000**, depending on condition.

- **Complete builds (engine transmission drivetrain)** in a **Dodge Viper or Mitsubishi 3000GT** are often **cheaper than restoring a modern supercar**.

- **Parts and labor costs** are generally lower than those for **LS engines, Gen V Mustangs, or modern turbocharged V8s**.

6. **Classic Performance Feel**

- The **high-revving NA V8 sound** is **musical and engaging**, appealing to enthusiasts who enjoy **manual transmission or stick-shift driving**.

- The **pushrod design** provides a **unique driving experience** compared to modern overhead-cam engines.

7. **Wide Availability of Replacement Parts**

- **Mitsubishi, Dodge, and aftermarket suppliers** (e.g., **JE, JEGS, Summit Racing**) stock **common components** like **valvetrains, pistons, crankshafts, and heads**.

- **Ebay, Craigslist, and specialty forums** (e.g., **Viper Forum, Mitsubishi 3000GT Club**) often have **used parts** at reasonable prices.

---

### **Cons of the AJ55TB3-16D**

1. **Thirst for Fuel and Oil**

- The AJ55TB3 **consumes oil** (especially with **high RPM or forced induction**), requiring **frequent oil checks** (every **500 1,000 miles** in tuned applications).

- **Fuel economy is poor** expect **around 10 12 MPG in stock form** and even worse with modifications.

- **High octane fuel (91 )** is recommended to prevent **detonation** under heavy boost or nitrous.

2. **Maintenance Requirements**

- **Valvetrain wear** is a **common issue** **valve springs, retainers, and lifters** wear out over time, requiring **regular inspection and replacement**.

- **Rod bearings and main bearings** can fail if **oil pressure drops** (due to **worn oil pump or low oil levels**).

- **Water pump and thermostat failures** are **not uncommon**, leading to **overheating** if not addressed.

- **Timing chain stretch** can occur over **100,000 miles**, requiring **chain replacement** (though some drivers run **timing chain stretchers** to extend life).

3. **Sensitivity to Boost and Tuning**

- The AJ55TB3 is **not naturally built for high boost** **stock bottom end (crank, rods, pistons) is not rated for excessive power**.

- **Forced induction (turbo/supercharger) requires careful tuning** to avoid **rod knock, bearing failure, or piston damage**.

- **Nitrous oxide (N2O) must be used with caution** **excessive use without proper cooling can cause catastrophic failure**.

4. **Weight and Size**

- The **5.0L V8 is heavy** ( **500 lbs**), which can affect **handling and fuel efficiency** in lighter vehicles.

- **Physical size** makes it **less practical for small cars** it was originally designed for **mid-size coupes and muscle cars**.

5. **Emissions and Modern Compliance Issues**

- **Stock AJ55TB3 engines do not meet modern emissions standards**, making them **illegal to drive in many areas** without modifications.

- **Aftermarket emissions solutions** (e.g., **catalytic converter bypasses, EGR deletions**) are required for street-legal operation.

- **OBD-II tuning** may be necessary to **disable emissions-related faults** on modern vehicles.

6. **Limited Modern Vehicle Applications**

- The AJ55TB3 was **discontinued in the 1990s**, so **new vehicles are not available**.

- **4-speed automatic (A405, A500, A604)** common in **Dodge Viper, Mitsubishi 3000GT**.

- **5-speed manual (545RFE, 545T)** found in **early Mitsubishi Eclipse GT**.

- **Modern vehicles may require **custom drivetrains** or **rebuilds** to fit properly.

7. **Potential for Hidden Damage**

- **Cracked cylinder heads** (especially on **early models**).

- **Worn camshaft lobes** (leading to **valve float at high RPM**).

- **Rod bearing or main bearing wear** (if oil changes were neglected).

- **Always get a **compression test, leak-down test, and oil analysis** before purchasing.**

8. **Noise and Vibration**

- The **pushrod design** can produce **more vibration** than modern DOHC engines, especially at **high RPM**.

- **Stock exhaust headers** can be **loud**, requiring **mufflers or aftermarket exhaust systems** for street-legal operation.

9. **Limited Warranty Coverage**

- Since the engine is **discontinued**, **no manufacturer warranty** is available.

- **Aftermarket warranties** (if any) are **short-term and often void with modifications**.

10. **Not Ideal for Daily Driving (Without Modifications)**

- **Stock power ( 300 hp) is strong but not excessive** most owners **modify it for higher performance**.

- **Fuel costs, maintenance, and noise** make it **less practical as a daily driver** unless heavily modified.
