Product Details
Upgrade your second-generation Acura Integra with the Innovative Mounts 49355 Steel Engine Mount and Cable-to-Hydraulic Transmission Conversion Kit, specifically engineered for 1990–1991 Acura Integra models and 1992–1993 Acura Integra GS-R applications equipped with compatible Honda B-Series engines.
Designed for the DA/DB chassis, the Innovative Mounts 49355 allows enthusiasts to install a compatible B-Series hydraulic manual transmission in place of the original cable-operated transmission. The kit also accommodates supported automatic-to-manual transmission conversions.
Featuring durable steel engine mounts, performance polyurethane bushings, and an included cable-to-hydraulic clutch conversion actuator, the 49355 provides the specialized mounting and clutch actuation components needed for a hydraulic transmission conversion.
Unlike conventional replacement engine mount kits, the 49355 is engineered around the unique mounting requirements of early second-generation Acura Integra models and the B17A1-powered Integra GS-R.
With CAD/CAM-engineered construction, stress-analyzed components, and Innovative Mounts' no-tear polyurethane bushings, this conversion kit helps improve drivetrain stability, reduce excessive engine movement, and maintain consistent engine and transmission positioning during acceleration and shifting.
Whether you're upgrading your B18A1-powered Integra, converting a B17A1 GS-R to a hydraulic manual transmission, or building a naturally aspirated or turbocharged B-Series performance car, the Innovative Mounts 49355 provides a purpose-built solution for your drivetrain conversion.
Designed for Second-Generation Acura Integra Applications
The Innovative Mounts 49355 is designed for two primary vehicle configurations:
1990–1991 Acura Integra RS, LS, and GS: Compatible B18A1 non-VTEC applications.
1992–1993 Acura Integra GS-R: Compatible B17A1 VTEC applications.
The kit accommodates supported chassis originally equipped with manual or automatic transmissions when converting to a compatible B-Series hydraulic manual transmission.
Key advantages include:
Application-specific mounting for supported second-generation Integra chassis.
Compatible with B18A1 and B17A1 engine configurations.
Designed for B-Series hydraulic manual transmission conversions.
Supports cable-to-hydraulic clutch conversion applications.
Accommodates supported automatic-to-manual conversions.
Includes a cable-to-hydraulic clutch conversion actuator.
Durable steel engine mount construction.
Performance polyurethane bushings.
Reduced excessive drivetrain movement.
Improved engine and transmission stability.
Multiple bushing hardness options.
Cable-to-Hydraulic Transmission Conversion
The second-generation Acura Integra originally utilized cable-operated manual transmissions.
When installing a later-generation B-Series hydraulic manual transmission, the clutch release system must be adapted to work with the vehicle's original clutch actuation arrangement.
The Innovative Mounts 49355 includes a cable-to-hydraulic conversion actuator designed to facilitate this conversion.
The actuator allows the existing cable-operated clutch system, when properly equipped, to operate the hydraulic clutch release mechanism of a compatible B-Series transmission.
This provides an alternative to converting the entire vehicle to a conventional hydraulic clutch pedal and master cylinder arrangement.
Benefits include:
Supports installation of a compatible hydraulic B-Series manual transmission.
Allows retention of the factory-style cable clutch pedal arrangement in supported manual chassis.
Provides a specialized clutch actuation solution.
Simplifies planning for cable-to-hydraulic transmission conversions.
Reduces the need for extensive clutch pedal and firewall modifications compared with a conventional hydraulic pedal conversion.
Works with the included engine mounting system.
Important: The actuator does not eliminate the need for a compatible hydraulic clutch slave cylinder, fluid line, and associated clutch components.
For vehicles originally equipped with an automatic transmission, additional pedal, cable, shifter, wiring, and clutch conversion components will be required.
Durable Steel Engine Mount Construction
The Innovative Mounts 49355 features steel mounting components engineered for dependable engine and transmission support.
Innovative Mounts utilizes CAD/CAM design technology and stress analysis to develop mounting systems intended for demanding performance applications.
The mounting components are engineered for proper drivetrain positioning in the supported chassis and transmission configurations.
No-Tear Performance Polyurethane Bushings
Factory Honda engine mounts rely on rubber damping components to isolate engine vibration from the chassis.
Over time, these mounts can deteriorate, crack, or lose their ability to control engine movement effectively.
The Innovative Mounts 49355 incorporates performance polyurethane bushings designed to reduce excessive drivetrain movement while providing varying levels of vibration isolation depending on the selected hardness.
Benefits include:
Reduced engine rocking during acceleration.
Improved drivetrain stability.
More consistent engine and transmission positioning.
Reduced mount deflection during shifting.
Improved throttle response.
Potential reduction in wheel hop.
Increased resistance to drivetrain movement.
Multiple bushing hardness options for street and competition applications.
