Upgrade your fourth-generation Honda Accord with the Innovative Mounts Steel F/H-Series Conversion Engine Mount Kit (29351), designed for 1990–1993 Honda Accord EX CB7/CB9 applications equipped with the factory manual-transmission chassis mounting configuration.

This performance-oriented engine mount kit is engineered for compatible H-Series engine conversions and installations using 1994–2001 F-Series manual transmissions. Featuring heavy-duty steel construction and Innovative Mounts' specially engineered polyurethane bushings, the 29351 provides improved drivetrain stability, reduced engine movement, and increased durability compared with aging factory rubber and hydraulic mounts.

The fourth-generation Honda Accord remains a popular platform for performance enthusiasts, particularly those building H22-powered street cars, naturally aspirated F-Series applications, and turbocharged Honda projects. However, upgrading the drivetrain often requires mounting components designed for the specific engine, transmission, and chassis combination.

The Innovative Mounts 29351 addresses these requirements with three performance engine and transmission mounts engineered to maintain proper drivetrain positioning in supported conversion applications.

Unlike conventional factory rubber mounts, Innovative Mounts' polyurethane bushings provide increased resistance to engine and transmission movement. This helps minimize excessive drivetrain rocking during acceleration, deceleration, and aggressive shifting.

Reducing unwanted drivetrain movement can improve shifting consistency, provide more predictable drivetrain response, and help minimize conditions that contribute to wheel hop during hard acceleration.

The kit features Innovative Mounts' proprietary no-tear polyurethane bushing design, developed to provide durable drivetrain support while maintaining vibration isolation appropriate to the selected bushing hardness.

Each mounting assembly is CAD/CAM designed and stress analyzed for strength, durability, and accurate fitment. The kit utilizes compatible factory Honda mounting hardware and is designed around the supported chassis mounting locations.

Important 4-Bolt Rear Mount Configuration

One of the most important characteristics of the Innovative Mounts 29351 is its four-bolt rear engine mount design.

The 1990–1993 Honda Accord was manufactured with different rear engine mount configurations depending on the original vehicle specification.

The Innovative Mounts 29351 is intended for vehicles using the taller, four-bolt rear mounting arrangement commonly associated with factory manual-transmission Accord EX models.

Vehicles equipped with the alternative three-bolt rear mounting arrangement require a different kit, such as Innovative Mounts 29350.

This distinction is critical because the rear engine mount must match the vehicle's rear subframe and mounting bracket configuration.

Transmission Mount Options

Innovative Mounts offers the 29351 with two passenger-side transmission mount configurations:

• 29320: For compatible factory manual-transmission mounting arrangements using a 1994–2001 F-Series or supported H-Series manual transmission.

• 29324: For supported automatic-to-manual transmission conversions using a compatible later F-Series or H-Series manual transmission.

Selecting the correct transmission mount configuration is essential for proper installation.

The kit also requires the 1990–1993 Honda Accord F-Series timing belt-side engine post, Honda part number 90008-PM3-000.

Available in 75A, 85A, and 95A polyurethane bushing hardness options, the Innovative Mounts 29351 allows enthusiasts to select the appropriate balance between street-driving comfort and performance-oriented drivetrain rigidity.

Whether you're completing an H22 engine swap, upgrading a modified F22-powered Accord, or building a dedicated Honda performance vehicle, the Innovative Mounts 29351 provides a dependable engine mounting solution for compatible four-bolt rear mount applications.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a supported 1990–1993 Honda Accord CB7/CB9 chassis.

2. Inspect the Rear Engine Mount Configuration: Verify that the vehicle uses the required four-bolt rear mounting arrangement.

3. Check Three-Bolt Applications: If the vehicle uses a three-bolt rear mount, evaluate Innovative Mounts 29350 instead.

4. Confirm Engine Configuration: Verify that the vehicle uses a compatible F-Series or H-Series engine.

5. Identify the Manual Transmission: Confirm that the transmission is a compatible H-Series manual or 1994–2001 F-Series manual transmission.

6. Select the Correct Passenger-Side Mount: Use the standard 29320 configuration for supported factory manual mounting arrangements or the 29324 configuration for supported automatic-to-manual conversions.

7. Confirm Required Timing Belt-Side Engine Post: Installation requires Honda part number 90008-PM3-000.

8. Support the Engine and Transmission: Properly support the drivetrain before removing the original mounting components.

9. Remove Existing Mounts: Follow the appropriate Honda service procedures when removing the original engine and transmission mounting assemblies.

10. Inspect Factory Mounting Locations: Check the chassis mounting points, engine brackets, transmission brackets, and surrounding components for damage or excessive wear.

11. Install the Driver-Side Engine Mount: Position the Innovative Mounts 29310 assembly according to the manufacturer's instructions.

12. Install the Passenger-Side Transmission Mount: Install the selected 29320 or 29324 assembly according to the transmission and chassis configuration.

13. Install the Four-Bolt Rear Engine Mount: Position the Innovative Mounts 29731 assembly in the corresponding rear mounting location.

14. Verify Hardware Compatibility: Use compatible original Honda mounting hardware and replace damaged or worn fasteners.

15. Align the Drivetrain: Ensure the engine and transmission are properly positioned before final tightening.

16. Avoid Bushing Preload: Confirm that the drivetrain is correctly supported and aligned to prevent unnecessary stress on the polyurethane bushings.

17. Torque Mounting Hardware: Tighten all fasteners according to Innovative Mounts' installation instructions and applicable Honda service specifications.
