Transform your first-generation Honda Insight into a K-Series-powered performance vehicle with the Innovative Mounts 90752 Steel K20 Engine Swap Mount Kit, specifically engineered for 2000–2006 Honda Insight ZE1 chassis originally equipped with an automatic transmission.

Designed for enthusiasts converting their factory automatic Honda Insight to a Honda K20 engine with a compatible manual transmission, the Innovative Mounts 90752 provides the specialized mounting components required to properly position and secure the K-Series drivetrain within the lightweight Insight chassis.

The first-generation Honda Insight is known for its lightweight aluminum construction, aerodynamic design, and exceptional efficiency. These characteristics also make it an interesting platform for performance enthusiasts seeking an unconventional Honda K-Series swap.

However, replacing the original ECA-series hybrid drivetrain with a K20 engine and manual transmission requires more than conventional replacement engine mounts. The factory automatic Insight chassis uses different mounting provisions than its manual-transmission counterpart, making conversion-specific mounting components essential.

The Innovative Mounts 90752 addresses these differences with a purpose-built steel mounting system featuring specialized driver-side and passenger-side brackets, a rear engine mount, and performance polyurethane bushings.

Unlike conventional factory rubber mounts, Innovative Mounts' polyurethane bushings are engineered to resist excessive engine movement during acceleration, deceleration, and shifting. This helps maintain more consistent drivetrain positioning while improving responsiveness under load.

Featuring CAD/CAM-engineered mounting geometry, stress-analyzed components, and Innovative Mounts' no-tear polyurethane bushing design, the 90752 is an excellent foundation for naturally aspirated K20 builds, turbocharged applications, drag racing projects, and dedicated motorsport vehicles.

Important: Part number 90752 is specifically designed for Honda Insight ZE1 chassis originally equipped with an automatic transmission and being converted to a K20 engine with a manual transmission. It is not compatible with factory-manual Insight chassis or K24 engine conversions.

Available Polyurethane Bushing Hardness Options

75A – Black – Street / Performance

The softest available bushing option for the 90752.

Recommended for street-oriented K20 Insight 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
