Review HONDA Rear Engine Transmission Mount Motor Oem #243 fits CRX 1989

The **Honda 50810-SH3-020 1989 89 CRX Rear Engine Transmission Mount** is a precision-engineered, high-performance suspension component designed exclusively for Honda s iconic **1989 CRX (FA2) model**, particularly those equipped with the **243 engine variant**. This mount serves as a critical link between the rear engine assembly and the transmission, ensuring optimal alignment, stability, and power transfer while minimizing vibration and noise during aggressive driving. Crafted from durable **high-strength rubber and reinforced steel**, this mount is engineered to withstand the demands of spirited driving, including high-speed cornering, hard acceleration, and sustained load-bearing under dynamic conditions. Its robust construction helps maintain proper engine-to-transmission alignment, reducing unnecessary strain on the drivetrain and preventing premature wear on related components such as the clutch, flywheel, or rear subframe. Ideal for both stock and modified applications, this mount is a straightforward yet essential upgrade for enthusiasts seeking to enhance drivability, reduce harshness, and extend the lifespan of their CRX s rear engine bay. Whether restoring a classic CRX to factory specifications or fine-tuning a performance build, this **OEM-replacement part** ensures compatibility with the original 1989 CRX s suspension geometry, making it a must-have for anyone prioritizing reliability and precision in their Honda.

### **Pros and Cons of buying a Honda 50810-SH3-020 (1989 89 CRX Rear Engine Transmission Mount Motor 243)**

#### **Pros:**

1. **Reliability and Durability** Honda engines, especially from the late 1980s, are known for their robust construction and longevity when properly maintained. The **B16A engine** (used in the CR-X) is a well-regarded inline-four with a reputation for lasting well over 200,000 miles with good care.

2. **Performance Potential** The **B16A** (2.0L) in the CR-X is a naturally aspirated engine that can be easily modified for better performance. It responds well to upgrades like intake/exhaust tweaks, ECU remapping, or even forced induction (turbo/supercharger) if properly supported.

3. **Aftermarket Support** The **CR-X (DF22)** platform is a popular choice among tuners, with a vast selection of parts, mods, and tuning solutions available. This makes it easier to customize and maintain compared to some less common engines.

4. **Lightweight & Compact** The rear-engine layout of the CR-X contributes to a balanced, nimble driving experience. The engine s compact size also makes it easier to work on in a home garage.

5. **Fuel Efficiency** The **B16A** is relatively efficient for its time, especially when compared to larger V6 or turbocharged engines. With proper maintenance, it can still achieve decent MPG in modern driving conditions.

6. **Classic & Collectible Status** The **1989 CR-X** (especially in DF22 form) is a sought-after classic, meaning parts and restoration projects can be rewarding for enthusiasts. Its retro styling and sporty handling make it a fun daily driver or track car.

7. **Transmission Compatibility** The **50810-SH3-020** is a **rear engine transmission mount**, which means it s designed to fit the **B16A engine** with either a **5-speed manual (B16A1)** or **4-speed automatic (B16A2)** transmission. This flexibility is useful if you plan to swap transmissions later.

8. **Lower Cost of Ownership (Compared to Modern Cars)** Parts, labor, and maintenance costs are generally lower than those of modern vehicles, making it a budget-friendly option for enthusiasts.

#### **Cons:**

1. **Age & Wear** A **1989 engine** (even if well-maintained) will have accumulated mileage and wear. If the engine has high mileage (e.g., 200,000 miles), you may need to budget for **valve stem seals, timing belt (if still original), or cylinder head work** soon.

2. **Timing Belt & Water Pump Replacement** The **B16A** uses an **interference engine**, meaning a broken timing belt can cause severe internal damage. If the belt hasn t been replaced recently, this is a **critical maintenance item** before purchase.

3. **Electrical & Sensor Issues** Older Honda engines (especially pre-1990s) can develop **faulty sensors, wiring problems, or fuel system issues** (e.g., carburetor or early fuel injection problems). A **full electrical and fuel system check** is essential.

4. **Rust & Corrosion** If the car has been exposed to harsh conditions (salt, humidity), **rust in the subframe, suspension, or exhaust** can be a major concern. A thorough inspection is necessary.

5. **Limited Modern Safety & Comfort** The **CR-X lacks modern safety features** (no ABS, side airbags, or advanced driver aids). It also has **basic suspension tuning** compared to modern cars, which may affect comfort on rough roads.

6. **Parts Availability** While parts exist, some **specialty items (e.g., rare OEM components, specific aftermarket mods)** may be harder to find than in newer vehicles. Patience and research may be required.

7. **Fuel & Emissions Compliance** If you plan to drive this car frequently, you may need to **modify the exhaust or fuel system** to meet modern emissions standards, which can be costly.

8. **Potential for Hidden Damage** Without a **pre-purchase inspection (PPI)**, you risk buying an engine with **internal wear, warped heads, or leaking seals**. Always verify compression, leak-down, and overall condition before committing.

### **Conclusion:**

The **Honda 50810-SH3-020 (1989 CR-X rear engine transmission mount)** is an **excellent choice for an enthusiast** who values **performance, reliability, and mod potential**. It s a **great engine for a project car, track day vehicle, or a fun daily driver** if you re willing to invest time in maintenance and upgrades.

However, **buying an older engine (especially without a full inspection) carries risks**, including **hidden wear, electrical issues, or rust problems**. If you re **mechanically inclined and prepared for maintenance**, this engine offers **long-term value and enjoyment**. If you re **not comfortable with classic car repairs**, the **upfront and long-term costs** may outweigh the benefits.

### **Recommendation:** - **If you re buying for a project or restoration:**

- **Get a full pre-purchase inspection** (focus on timing belt, cylinder head seals, and electrical system).

- **Verify compression and leak-down** to ensure the engine is in good health.

- **Budget for necessary upgrades** (fuel system, exhaust, suspension, and safety mods if needed).

- **Consider buying from a reputable seller** (e.g., a trusted mechanic, auction with inspection, or a known Honda enthusiast).

- **If you re buying as a daily driver:**

- **Ensure the car has low mileage (under 150,000 miles) and recent maintenance records.**

- **Prioritize rust-free examples** (especially in the subframe, exhaust, and suspension).

- **Be prepared for higher insurance costs** due to age and lack of modern safety features.

- **Best use cases:**

- **Track day / autocross car** (with proper mods).

- **Project car for restoration** (if you enjoy working on classics).

- **Enthusiast s daily driver** (if you don t mind occasional maintenance).

**Final Verdict:** **Worth it for the right buyer** someone who appreciates **Honda engineering, enjoys modifications, and is willing to put in the work**. Not ideal for **casual drivers** looking for a hassle-free vehicle.
