Available Polyurethane Bushing Hardness Options

75A – Black – Street / Performance

The softest listed option for the 90150.

Recommended for performance-oriented street vehicles where improved drivetrain stability is desired while retaining some vibration isolation.

Manufacturer horsepower guidance: approximately 250–400 HP.

85A – Grey – Performance / Race

Provides increased drivetrain rigidity for modified engines, aggressive driving, and competition applications.

Manufacturer horsepower guidance: approximately 400–500 HP.

95A – Red – Extreme Race

The stiffest listed polyurethane option, intended for high-output engines and dedicated racing applications.

Manufacturer horsepower guidance: 500+ HP.

These horsepower ranges are manufacturer selection guidelines rather than guaranteed load ratings.

Important: Firmer polyurethane bushings generally increase noise, vibration, and harshness transmitted into the vehicle cabin.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a supported 1992–1995 Honda Civic or 1994–2001 Acura Integra.

2. Confirm Engine Compatibility: Identify the exact Honda K-Series engine being installed.

3. Verify Transmission Compatibility: Confirm that the selected transmission is a compatible K20-style manual transmission.

4. Check K24 Engine Requirements: When installing a compatible K24 engine, obtain Honda engine bracket 11910-PPA-000.

5. Plan the Complete 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 mounting points, frame rails, and subframe 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 or Acura 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 driver-side, passenger-side, and rear mounts according to the manufacturer's instructions.

12. Install the Custom Frame Brackets: Secure the supplied application-specific frame brackets using the appropriate mounting hardware.

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 or Acura 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.

20. Recheck After Initial Use: Inspect mounting hardware and drivetrain components after the initial driving period.

Professional installation is strongly recommended, as K-Series engine conversions require careful drivetrain integration and supporting modifications.
