Review PROTHANE Acura Rear Motor Mount Insert Black fits INTEGRA 1990–1993

The **Prothane 636169069918 8-512-BL 90-93 Acura Integra Rear Motor Mount** is a high-performance, precision-engineered suspension component designed specifically for the 1990 through 1993 Acura Integra models, ensuring optimal engine support, alignment, and drivability. Crafted from durable, reinforced rubber and high-grade synthetic materials, this motor mount is engineered to withstand the rigors of daily driving, track use, and high-performance applications while maintaining structural integrity and reducing engine vibration. The mount features a robust, bolt-on design with a reinforced steel bracket, providing superior load-bearing capacity and minimizing flex under heavy engine loads, which is particularly beneficial for vehicles equipped with turbocharged or high-horsepower setups. Its precise fitment ensures seamless integration with the Integra s rear engine bay, aligning perfectly with the stock mounting points while offering enhanced durability compared to standard OEM parts. Whether you're seeking improved ride quality, reduced engine noise, or a more robust suspension setup for modified engines, this Prothane motor mount delivers reliable performance and longevity. Built to meet or exceed factory specifications, it is an excellent choice for both restoration projects and performance-oriented builds, ensuring a smooth, stable, and responsive driving experience.

**Pros and Cons of buying a Prothane 636169069918 8-512-BL (90-93 Acura Integra Rear Motor Mount)**

1. **Compatibility and Fit:** This part is specifically designed for the 1990-1993 Acura Integra (and related Honda Civic models), ensuring a proper fit without modifications. It replaces the stock rear motor mount, which can wear out over time, leading to excessive engine movement and potential driveline issues.

2. **Durability:** Prothane is a well-known brand in the aftermarket suspension and engine support industry, known for producing high-quality rubber and polyurethane components. Their motor mounts are designed to withstand the rigors of daily driving, reducing the risk of premature failure compared to OEM parts.

3. **Reduced Vibration and Noise:** Worn-out motor mounts can cause rattling, clunking noises, and excessive engine movement, especially during acceleration or over bumps. A new Prothane mount should eliminate these issues, providing a smoother ride and quieter cabin.

4. **Improved Engine Support:** The Prothane mount is engineered to provide better support to the engine, reducing strain on the drivetrain components (such as the transmission and rear subframe) and potentially extending their lifespan.

5. **Ease of Installation:** While installation requires some mechanical skill (typically involving removing the rear subframe and old mount), Prothane provides clear instructions and compatible hardware. Many users report that the process is straightforward if you have basic tools and experience working on a car.

6. **Cost-Effective Solution:** Replacing a worn motor mount is often cheaper than ignoring the issue, which could lead to more severe problems (e.g., transmission damage, driveline misalignment, or even engine detachment in extreme cases). The Prothane mount offers a balance between affordability and quality.

7. **Warranty and Support:** Prothane stands behind its products with a warranty (typically 1-2 years), and their customer service is generally responsive. This provides peace of mind in case of defects or installation issues.

1. **Installation Complexity:** Replacing the rear motor mount on an Integra (especially the 90-93 models) is not a simple job. It requires lifting the car, removing the rear subframe, disconnecting the driveshaft, and replacing the mount. This may not be feasible for DIYers without experience in suspension or drivetrain work. Professional labor could significantly increase the cost.

2. **Tooling Requirements:** Specialized tools may be needed, such as a subframe jack, torque wrench, and possibly a driveshaft separator tool. Some users may need to purchase or rent these tools, adding to the overall expense.

3. **Potential for Hidden Damage:** If the mount has been failing for a while, other components (e.g., the rear subframe bushings, driveshaft yokes, or transmission mounts) may also be worn. Inspecting these parts during installation is crucial, and replacements may be necessary, increasing costs.

4. **Quality Variability:** While Prothane is a reputable brand, there have been occasional reports of inconsistent quality in some batches. Ensuring you purchase a genuine part from an authorized dealer or trusted seller (e.g., RockAuto, Summit Racing, or a local auto parts store) can mitigate this risk.

5. **Time-Consuming:** The job can take several hours, especially for a first-time installer. This may not be ideal for those with limited time or patience for automotive repairs.

6. **Risk of Over-Tightening:** Motor mounts are sensitive to torque specifications. Over-tightening can damage the mount or the subframe, while under-tightening can lead to premature failure. Following the manufacturer s torque values (often included in the installation instructions) is critical.

7. **Secondary Issues:** In some cases, replacing just the motor mount may not fully resolve driveline or suspension problems if other components (e.g., the rear subframe bushings or driveshaft) are worn. A thorough inspection is recommended before and after installation.

The Prothane 636169069918 8-512-BL rear motor mount is a solid aftermarket replacement for the 1990-1993 Acura Integra, offering improved durability, reduced vibration, and better engine support compared to the original equipment. Its compatibility and reputation for quality make it a reliable choice for addressing motor mount failure. However, the installation is labor-intensive and may require professional assistance unless you have experience with suspension or drivetrain work. The potential for hidden damage and the need for precise torque application are also factors to consider.

That said, if you re uncomfortable with the installation process, consulting a mechanic may be the safer option.

- **Buy the Prothane mount** if you re confident in your ability to perform the installation or are willing to pay for professional labor. It s a worthwhile upgrade for reliability and ride quality.

- **Inspect other related components** (subframe bushings, driveshaft, transmission mounts) during installation to avoid future problems.

- **Purchase from a trusted source** to ensure you re getting an authentic Prothane part with a warranty.

- **Follow the installation instructions carefully**, including torque specifications, to avoid damaging the mount or subframe.

- **Consider professional installation** if you lack experience with suspension work, as this can save time and reduce the risk of mistakes.
