Upgrade your sixth-generation Honda Civic with the Innovative Mounts 90050 Steel K-Series Engine Swap Mount Kit, engineered for installing compatible Honda K20 or K24 engines with a K20-style manual transmission into the 1996–2000 Honda Civic chassis.

Designed for Civic EK, EJ, and EM applications, the Innovative Mounts 90050 provides the engine and transmission mounting components needed to replace the factory D-Series or B-Series drivetrain with a Honda K-Series powertrain.

Unlike swap mount kits requiring an earlier EG subframe, the Innovative Mounts 90050 is designed to work with the factory EK-style front subframe, making it an attractive option for enthusiasts who want to retain their original subframe configuration.

Featuring durable steel construction, CAD/CAM-engineered mounting geometry, stress-analyzed components, and Innovative Mounts' no-tear polyurethane bushings, this conversion kit helps reduce excessive engine movement, improve drivetrain stability, and maintain consistent engine and transmission positioning.

Whether you're building a naturally aspirated K20-powered Civic, a high-torque K24 street car, or a turbocharged K-Series performance project, the Innovative Mounts 90050 provides a purpose-built mounting solution for your engine swap.

Designed for 1996–2000 Honda Civic K-Series Swaps

The sixth-generation Honda Civic is one of the most popular platforms for Honda engine conversions.

The Innovative Mounts 90050 is engineered for compatible 1996–2000 Civic chassis originally equipped with either a manual or automatic transmission.

The completed K-Series conversion must use a compatible K20-style manual transmission.

Key benefits include:

• Application-specific mounting for 1996–2000 Honda Civic chassis.

• Compatible with factory manual or automatic chassis configurations.

• Supports compatible Honda K20 and K24 engines.

• Designed for K20-style manual transmissions.

• Retains the factory EK-style front subframe.

• Durable steel engine and transmission mounting components.

• Performance polyurethane bushings.

• Reduced excessive drivetrain movement.

• Improved engine and transmission stability.

• Multiple bushing hardness options for street and competition use.

Retains the Factory EK Front Subframe

One of the most important features of the Innovative Mounts 90050 is its compatibility with the factory EK-style front subframe.

Some K-Series conversion mounting systems require the installation of an earlier 1992–1995 Honda Civic EG subframe.

The Innovative Mounts 90050 is specifically designed for the 1996–2000 Civic using the original EK-style subframe arrangement.

This allows builders to retain the appropriate factory subframe while installing the specialized mounting components required for a K-Series conversion.

Important: The 90050 is intended for the stock EK-style subframe configuration. It should not be confused with mount kits designed around an EG subframe conversion.

Honda K20 and K24 Engine Compatibility

Honda's K-Series engine family offers excellent aftermarket support, strong performance potential, and extensive tuning options.

The Innovative Mounts 90050 supports compatible K20 and K24 engine installations when paired with the correct K20-style manual transmission.

Popular engine applications include:

• Honda K20A

• Honda K20A2

• Honda K20A3

• Honda K20Z1

• Honda K20Z3

• Honda K24A

• Honda K24A2

Other K-Series engines may be compatible depending on the engine block, mounting brackets, accessory arrangement, and transmission configuration.

Important: K24 engine compatibility does not mean K24 transmission compatibility. The 90050 requires a compatible K20-style manual transmission.

K20 Manual Transmission Compatibility

The Innovative Mounts 90050 is designed for compatible Honda and Acura K20-style manual transmissions.

Common transmission donor applications include:

• 2002–2006 Acura RSX manual transmissions

• 2002–2005 Honda Civic Si manual transmissions

• Other compatible K20-style manual transmission configurations

The kit is not compatible with the Acura TSX K24 manual transmission.

Other K24-style transmissions, including certain Honda Accord applications, are also not supported by this mounting configuration.

Confirm the exact transmission case and mounting arrangement before ordering.

Durable Steel Mount Construction

The Innovative Mounts 90050 features steel mounting components engineered for performance drivetrain applications.

Innovative Mounts utilizes CAD/CAM engineering and stress analysis to develop mounting systems designed for consistent fitment and dependable drivetrain support.

The steel construction provides a durable mounting foundation for compatible naturally aspirated and forced-induction K-Series builds.

Performance Polyurethane Bushings

Factory Honda engine mounts use rubber damping components designed to isolate engine vibration from the chassis.

While effective for everyday driving, factory-style mounts can allow excessive engine movement during aggressive acceleration, shifting, and performance driving.

The Innovative Mounts 90050 incorporates no-tear polyurethane bushings designed to provide increased resistance to drivetrain movement.

Benefits include:

• Reduced excessive engine rocking.

• Improved drivetrain stability.

• More consistent engine and transmission positioning.

• Reduced mount deflection during acceleration.

• Improved drivetrain responsiveness.

• Potential reduction in wheel hop.

• Increased resistance to drivetrain movement.

• Multiple bushing hardness options.

5. Plan the Complete K-Series Conversion: Obtain the appropriate engine, transmission, axles, intermediate shaft, shifter, wiring, ECU, cooling system, and other supporting components.

6. Prepare Automatic Chassis Components if Applicable: Vehicles originally equipped with automatic transmissions require additional manual conversion components.

7. Inspect Factory Mounting Locations: Check the chassis brackets, frame rails, and subframe mounting points for damage or corrosion.

8. Support the Vehicle and Drivetrain: Use appropriate lifting equipment and engine support tools.

9. Remove the Factory Drivetrain: Follow applicable Honda service procedures.

10. Prepare the K-Series Engine: Install the correct engine-side mounting brackets and supporting swap components.

11. Install the Innovative Mounts Components: Position the engine and transmission mounts according to the manufacturer's installation instructions.

12. Install the Required Sub-Brackets: Secure the application-specific mounting brackets according to the manufacturer's procedures.

13. Verify Engine and Transmission Positioning: Ensure the drivetrain is properly aligned and the mounts are not binding.

14. Inspect Axle Fitment: Confirm proper axle engagement, operating angles, and clearance.

15. Check Engine Bay Clearance: Verify clearance around the subframe, steering components, exhaust system, intake components, and surrounding accessories.

16. Complete Supporting Systems: Install and verify the ECU, wiring, cooling, fuel, clutch, and shifter components.

17. Torque Mounting Hardware: Follow Innovative Mounts' installation instructions and applicable Honda factory torque specifications.

18. Perform a Final Inspection: Check all mounting hardware, drivetrain clearances, fluid connections, and transmission operation before driving.

19. Check for Excessive Vibration: Some increase in vibration is normal with performance polyurethane mounts, particularly with firmer bushing options.
