Engineered to provide a strong, reliable mounting solution for Honda B-Series engine conversions, this three-piece performance mount kit allows enthusiasts to install a compatible B-Series engine and cable transmission into a factory D-Series-powered Civic or CRX chassis.

The lightweight 1988–1991 Honda Civic and CRX platforms are popular choices for B-Series engine swaps thanks to their compact dimensions, excellent handling characteristics, and extensive aftermarket support. Installing a B16, B18, or other compatible B-Series engine can significantly improve performance, but the conversion requires an engine mounting system designed to correctly position the larger drivetrain.

Innovative Mounts addresses this requirement with a heavy-duty steel conversion mount kit engineered specifically for the ED/EE/EF chassis. Unlike universal mounting solutions, the 19150 is designed to position the engine and transmission correctly within the engine bay while maintaining proper axle alignment.

The kit includes three primary mounting assemblies: a driver-side engine mount, passenger-side transmission mount, and rear engine mount. Together, these components provide the foundation for a properly supported B-Series drivetrain.

Each mount features durable steel construction and Innovative Mounts' specially engineered no-tear polyurethane bushings. Compared with conventional factory rubber mounting components, the polyurethane design provides increased resistance to engine movement during acceleration, deceleration, and aggressive shifting.

Reducing unwanted drivetrain movement can help improve throttle response consistency, minimize wheel hop, and maintain more predictable drivetrain positioning under load. These benefits are especially valuable for modified naturally aspirated B-Series engines, turbocharged applications, and competition vehicles.

The Innovative Mounts 19150 is CAD/CAM designed and stress analyzed for strength, durability, and accurate fitment. Its bolt-on design utilizes compatible factory mounting locations and original hardware where specified.

A compatible 1990–1993 Acura Integra timing belt-side engine bracket, Innovative Mounts B59350, is required for installation. Certain taller-deck B-Series configurations may also require minor trimming of the underside of the factory hood to provide sufficient engine clearance.

Available with several polyurethane bushing hardness options, the Innovative Mounts 19150 allows enthusiasts to select the appropriate balance between street-driving comfort and performance-oriented drivetrain rigidity.

Whether you're installing a B16A into an EF Civic hatchback, converting a CRX Si to B18 power, or preparing a turbocharged B-Series build for competition, the Innovative Mounts 19150 provides the drivetrain mounting solution needed for a dependable engine swap.
