Designed for enthusiasts replacing the factory F20C or F22C1 engine with a Honda K24 i-VTEC engine, the Innovative Mounts 90757 provides the specialized mounting components needed to properly position and secure the K-Series drivetrain within the S2000 chassis.

The Honda S2000 is known for its lightweight rear-wheel-drive platform, exceptional handling, and high-revving factory engine. While the original F-Series engine delivers impressive performance, converting to a K24 opens the door to increased displacement, improved torque potential, and extensive aftermarket performance support.

However, installing a K24 engine into an S2000 requires specialized mounting components to accommodate the differences between the factory F-Series drivetrain and the replacement K-Series engine.

The Innovative Mounts 90757 addresses these requirements with a purpose-built steel mounting system featuring front and passenger-side adapter plates, conversion-specific brackets, and performance polyurethane bushings.

Unlike conventional factory rubber mounts, Innovative Mounts' polyurethane bushings help reduce excessive engine movement during acceleration, deceleration, and shifting. This provides more consistent drivetrain positioning and improved responsiveness under load.

Featuring CAD/CAM-engineered components, stress-analyzed construction, and Innovative Mounts' no-tear polyurethane bushing design, the 90757 is an excellent mounting solution for naturally aspirated K24 builds, turbocharged applications, road racing projects, and dedicated motorsport vehicles.

Important: The Innovative Mounts 90757 is specifically designed for K24 engine conversions using a compatible manual transmission and the appropriate adapter-plate configuration. It is not a direct-replacement mount kit for the original F20C/F22C1 engine or a K20-specific conversion kit.

Available Polyurethane Bushing Hardness Options

75A – Black – Street / Performance

The softest available bushing option for the 90757.

Recommended for street-oriented K24 S2000 conversions 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 available polyurethane option, intended for high-output engines and dedicated racing applications.

Manufacturer horsepower guidance: 500+ HP.

These horsepower ranges are general manufacturer bushing selection guidelines rather than guaranteed load ratings or minimum horsepower requirements.

Important: Increasing bushing hardness generally increases noise, vibration, and harshness transmitted into the vehicle cabin. The 75A option is typically the most appropriate starting point for a street-driven S2000 conversion.
