The sixth-generation Honda Accord is an excellent platform for H-Series engine conversions, offering a spacious engine bay, a well-balanced chassis, and significant performance potential. Installing an H22 or H23 engine can provide increased horsepower and torque, but proper drivetrain positioning requires engine mounts designed for the specific engine, transmission, and chassis combination.

Innovative Mounts addresses this requirement with a heavy-duty steel conversion mount kit engineered to position a compatible H-Series drivetrain in the 1998–2002 Accord chassis while providing increased resistance to engine movement.

The Innovative Mounts 20252 includes three primary mounting assemblies and a conversion-specific driver-side mounting bracket. Together, these components provide the engine and transmission mounting foundation needed for a supported H-Series manual-transmission conversion.

Unlike factory rubber and hydraulic engine mounts, Innovative Mounts' polyurethane bushings provide increased resistance to drivetrain deflection. This helps minimize unwanted engine movement during acceleration, deceleration, and aggressive shifting.

Reducing excessive drivetrain movement can help improve throttle response consistency, maintain more predictable shifting feel, and reduce conditions that contribute to wheel hop during hard acceleration.

The kit features Innovative Mounts' unique no-tear polyurethane bushing design, engineered to control engine movement while providing vibration isolation appropriate to the selected bushing hardness.

Each mounting component is CAD/CAM designed and stress analyzed for strength, durability, and accurate fitment. The kit is designed for bolt-on installation using compatible factory mounting locations and original Honda hardware where specified.

Important: Installation requires the 1992–2001 Honda Prelude H-Series timing belt-side engine post mount, Honda part number 11910-P13-000. This component must be present on the engine or sourced separately.

The 20252 uses a different driver-side mounting bracket than Innovative Mounts 20250. This distinction is important because the correct kit depends on the engine's timing belt-side mounting post configuration.

Available with 75A, 85A, or 95A polyurethane bushings, the Innovative Mounts 20252 allows enthusiasts to select the appropriate level of drivetrain rigidity for street performance, track use, or dedicated competition applications.

Whether you're installing an H22A into a sixth-generation Accord, completing a naturally aspirated VTEC performance build, or preparing a turbocharged H-Series project, the Innovative Mounts 20252 provides a durable mounting solution for your engine conversion.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a supported 1998–2002 Honda Accord CG3/CG5 four-cylinder chassis.

2. Confirm Engine Configuration: Verify that the engine uses a compatible H-Series mounting arrangement.

3. Verify Transmission Type: Innovative Mounts 20252 is designed for compatible manual-transmission conversions.

4. Confirm Required Timing Belt-Side Engine Post: Installation requires Honda part number 11910-P13-000, the specified Prelude H-Series engine post.

5. Check the Engine Post Before Installation: Do not assume that every H22 or H23 engine uses the correct post. Verify the installed bracket and mounting configuration.

6. Confirm the Correct Mount Kit: Vehicles using the F-Series / later H-Series engine post arrangement may require Innovative Mounts 20250 instead.

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

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

9. Install the Driver-Side Engine Mount: Position the Innovative Mounts 20210 assembly according to the manufacturer's instructions.

10. Install the H-Series Conversion Bracket: Install the included Innovative Mounts 20211-SB bracket in the designated mounting location.

11. Install the Passenger-Side Transmission Mount: Position the Innovative Mounts 20220 assembly according to the manufacturer's instructions.

12. Install the Rear Engine Mount: Position the Innovative Mounts 20230 manual-transmission rear mount in the designated mounting location.

13. Install the Specified Hardware: Use the supplied conversion hardware and compatible OEM fasteners in their designated locations.

14. Align the Drivetrain: Ensure the engine and transmission are correctly positioned before final tightening to prevent unnecessary bushing preload.

15. Verify Axle and Drivetrain Alignment: Confirm that the engine and transmission are positioned correctly and that compatible axles operate without binding.

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

17. Verify Component Clearance: Inspect clearance around the engine, transmission, exhaust system, intake components, radiator, axles, and surrounding chassis structure.

18. Check Hood Clearance: The kit is designed to avoid factory hood modifications for supported installations. Verify clearance before closing the hood.

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

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

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

22. Professional Installation Recommended: Installation by an experienced Honda engine swap specialist is strongly recommended.
