Upgrade your sixth-generation Honda Civic with the Innovative Mounts Steel B/D-Series Conversion Engine Mount Kit (10051), designed for 1996–2000 Honda Civic EK, EJ, and EM chassis and compatible with 1997–2000 Acura EL applications. Engineered for B-Series and D-Series engines using a 3-bolt GS-R-style driver-side engine post mount, this performance mounting system provides improved drivetrain stability, reduced engine movement, and increased durability for street and racing applications.

Whether you're installing a B18C engine into your Civic, replacing worn factory mounts, or upgrading your existing drivetrain for additional horsepower, the Innovative Mounts 10051 kit provides a reliable mounting solution designed to accommodate both manual and automatic hydraulic transmission configurations.

One of the key advantages of this conversion kit is its ability to accommodate B-Series engines equipped with the factory 3-bolt GS-R-style driver-side post mount, commonly found on 1994–2001 Acura Integra GS-R applications. This eliminates the need to replace the existing engine-side post mount when performing a compatible B-Series conversion.

Factory Honda engine mounts use rubber bushings designed primarily to isolate engine vibration and maximize everyday driving comfort. As these mounts age, the rubber can deteriorate, allowing excessive engine movement during acceleration, deceleration, and gear changes. This movement becomes particularly noticeable in modified vehicles producing more horsepower and torque than factory configurations.

Innovative Mounts addresses these limitations with heavy-duty steel mounting brackets and specially engineered polyurethane bushings. The firmer mounting system helps minimize drivetrain movement, improve throttle response, and reduce wheel hop by maintaining more consistent engine and transmission positioning under load.

Each mount is CAD/CAM designed and stress analyzed to provide reliable fitment and strength. The kit features durable steel construction, a corrosion-resistant finish, and Innovative Mounts' unique no-tear polyurethane bushings, available in multiple hardness options to suit different performance requirements.

Designed as a bolt-on conversion solution, the Innovative Mounts 10051 kit uses factory mounting hardware and does not require hood trimming or notching in compatible applications.

From daily-driven Civic builds to high-horsepower turbocharged B-Series conversions, this engine mount kit provides the durability, performance, and precise drivetrain support Honda enthusiasts demand.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a compatible 1996–2000 Honda Civic EK/EJ/EM or 1997–2000 Acura EL MB chassis.

2. Confirm Engine Post Mount Configuration: This kit requires a 3-bolt GS-R-style driver-side engine post mount. Engines equipped with a 2-bolt post mount require Innovative Mounts 10050 or another compatible mounting solution.

3. Verify Transmission Compatibility: Confirm that the engine is paired with a supported hydraulic manual or automatic transmission.

4. Support the Engine and Transmission: Properly support the drivetrain before removing the existing mounts to prevent unexpected movement or damage.

5. Remove Existing Engine Mounts: Follow the appropriate Honda or Acura service procedures when removing factory engine and transmission mounting components.

6. Inspect Chassis Mounting Locations: Check all factory mounting points, brackets, and surrounding chassis components for damage, corrosion, or previous modifications.

7. Install the Driver-Side Conversion Bracket: Position the supplied driver-side bracket according to Innovative Mounts' installation instructions.

8. Install the Engine Mount Assemblies: Position the three replacement engine mounts in their designated mounting locations, ensuring proper alignment and orientation.

9. Reuse Factory Mounting Hardware: This kit is designed to utilize original Honda/Acura hardware. Inspect all bolts and fasteners before reuse and replace any damaged components.

10. Align the Drivetrain: Ensure the engine and transmission are properly positioned before final tightening to avoid unnecessary mount preload.

11. Torque Mounting Hardware: Tighten all fasteners according to the applicable manufacturer specifications. Avoid overtightening or improperly loading the polyurethane bushings.

12. Verify Hood and Component Clearance: Although the kit is designed to install without hood trimming, confirm adequate clearance around the engine, transmission, intake, exhaust, and surrounding components.

13. Select the Appropriate Bushing Hardness: Choose the polyurethane durometer that best matches the vehicle's intended use, horsepower level, and acceptable vibration.

14. Expect Increased Engine Vibration: Performance polyurethane mounts generally transmit more engine vibration into the chassis than factory rubber mounts. Higher-durometer bushings typically increase vibration further.

15. Inspect After Installation: Recheck mounting hardware, drivetrain alignment, and surrounding clearances after the initial driving period.

16. Professional Installation Recommended: Installation by an experienced Honda/Acura performance technician is strongly recommended.

17. Confirm Fitment Before Bolting Down: Innovative Mounts states that mounts showing installation bolt impressions cannot be returned or exchanged. Verify all mounting requirements before installation.
