Upgrade your Honda or Acura with the Innovative Mounts B90150 Billet Aluminum K-Series Engine Conversion Mount Kit, designed for compatible 1992–1995 Honda Civic and 1994–2001 Acura Integra chassis undergoing a Honda K20 or K24 engine swap.

The B90150 provides a performance-oriented mounting solution for installing a compatible K-Series engine and manual transmission into the popular EG Civic and DC Integra platforms. Featuring billet aluminum mounting components and performance polyurethane bushings, this kit is engineered to improve drivetrain stability while delivering a premium engine bay appearance.

Honda's K-Series engine family has become a popular choice for engine conversions thanks to its modern DOHC i-VTEC technology, strong aftermarket support, and impressive naturally aspirated and forced-induction performance potential.

Whether you're building a high-revving K20-powered Civic, a torque-focused K24 Integra, or a turbocharged K-Series project, the Innovative Mounts B90150 provides the specialized mounting components necessary for a properly configured drivetrain conversion.

Unlike conventional factory rubber engine mounts, which prioritize passenger comfort and vibration isolation, Innovative Mounts' performance polyurethane bushings are designed to reduce excessive drivetrain movement during acceleration, deceleration, and shifting.

Reduced mount deflection helps maintain more consistent engine and transmission positioning under load, potentially improving shifting feel and minimizing wheel hop caused by drivetrain movement.

The billet aluminum construction also provides an attractive alternative to traditional steel engine conversion mounts, making the B90150 an excellent choice for performance street cars, detailed engine bays, autocross builds, drag racing applications, and dedicated track vehicles.

Important: The B90150 is a K-Series engine conversion mount kit, not a complete engine swap package. Additional drivetrain, wiring, clutch, cooling, and fuel system components are required.

Polyurethane Bushing Selection

Innovative Mounts performance mounting systems are commonly offered with several polyurethane bushing hardness options. Confirm the available B90150 configurations before selecting a kit.

60A – Street

A softer performance bushing option for vehicles where improved drivetrain stability is desired while limiting additional vibration.

75A – Performance Street

A firmer option for modified street vehicles and occasional track use.

85A – Race

Designed for applications where increased drivetrain rigidity is preferred over passenger comfort.

95A – Extreme Race

A very firm polyurethane configuration intended for aggressive motorsport use.

Important: Firmer bushings generally transmit more noise, vibration, and harshness into the vehicle. Select the appropriate configuration based on vehicle use and acceptable cabin vibration.
