Complete your fourth-generation Honda Accord manual transmission conversion with the Innovative Mounts Steel F-Series Conversion Engine Mount Kit (29358), specifically engineered for 1990–1993 Honda Accord DX and LX models originally equipped with an automatic transmission and being converted to a compatible 1990–1993 F-Series manual transmission.

Converting a factory automatic Honda Accord to a manual transmission requires more than replacing the transmission itself. Differences between factory automatic and manual transmission mounting configurations can make it difficult to properly position and secure the drivetrain using original mounting components.

The Innovative Mounts 29358 addresses these challenges with a purpose-built three-piece conversion kit designed for the fourth-generation Accord CB7/CB9 chassis.

This kit includes the driver-side engine mount, passenger-side manual transmission conversion mount, and rear engine mount. Together, these components provide the primary mounting support required for the specified automatic-to-manual drivetrain conversion.

Unlike conventional factory rubber or hydraulic mounts, Innovative Mounts' performance polyurethane bushings provide increased resistance to engine and transmission movement. This helps maintain more consistent drivetrain positioning during acceleration, deceleration, and shifting.

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

Each mounting assembly features Innovative Mounts' unique no-tear polyurethane bushing design, engineered for durability while providing vibration isolation appropriate to the selected bushing hardness.

The kit features heavy-duty steel construction and is CAD/CAM designed and stress analyzed for strength, durability, and accurate fitment.

Designed for Early F-Series Manual Transmissions

One of the most important characteristics of the Innovative Mounts 29358 is its compatibility with the 1990–1993 F-Series manual transmission.

This kit is specifically designed for Honda Accord DX/LX vehicles originally equipped with an automatic transmission and being converted to an early F-Series manual drivetrain.

The passenger-side transmission conversion mount, Innovative Mounts 29325, accommodates the required mounting arrangement for this conversion.

If you're installing a later 1994–2001 F-Series manual transmission or a compatible H-Series manual transmission, the appropriate conversion kit is Innovative Mounts 29359.

Important Rear Engine Mount Configuration

The Innovative Mounts 29358 includes the 29630 rear engine mount, designed for the shorter three-bolt rear mounting configuration used in supported Accord DX/LX applications.

Vehicles equipped with a different rear mounting arrangement must be evaluated separately before ordering.

Required Engine Mounting Post

Installation requires the original-style 1990–1993 Honda Accord F-Series timing belt-side engine post.

Innovative Mounts references Honda part number 90008-PM3-000 in its product requirements. Verify the actual engine post and associated mounting hardware before installation.

Available in 75A, 85A, and 95A polyurethane bushing hardness options, the Innovative Mounts 29358 allows enthusiasts to select the appropriate level of drivetrain rigidity for street performance, track use, or competition applications.

Whether you're converting your CB7 Accord to a five-speed manual transmission, building a modified F22A-powered street car, or completing a fourth-generation Accord restoration, the Innovative Mounts 29358 provides a dependable mounting foundation for your project.

Installation Notes

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

2. Confirm Original Transmission Configuration: The Innovative Mounts 29358 is intended for compatible factory automatic chassis being converted to a manual transmission.

3. Identify the Manual Transmission: Verify that the transmission being installed is a compatible 1990–1993 F-Series five-speed manual.

4. Check Later Transmission Applications: If installing a 1994–2001 F-Series or compatible H-Series manual transmission, evaluate Innovative Mounts 29359 instead.

5. Verify the Rear Mount Configuration: Confirm that the vehicle uses the required three-bolt rear mounting arrangement.

6. Confirm the Timing Belt-Side Engine Post: Verify that the correct original-style 1990–1993 Accord F-Series engine post is installed or available.

7. Support the Engine and Transmission: Properly support the drivetrain before removing existing mounting components.

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

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

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

11. Install the Passenger-Side Transmission Conversion Mount: Position the Innovative Mounts 29325 assembly at the designated transmission mounting location.

12. Install the Rear Engine Mount: Position the Innovative Mounts 29630 assembly at the three-bolt rear mounting location.

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

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

15. Avoid Bushing Preload: Confirm proper drivetrain alignment to prevent unnecessary stress on the polyurethane bushings.

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

17. Verify Axle Alignment: Confirm that the drivetrain maintains appropriate axle positioning and clearance.

18. Complete the Manual Conversion: Install and verify all required manual transmission components, including the clutch system, pedals, shifter assembly, and other conversion-specific parts.
