Designed for 1994–2001 Acura Integra Automatic-to-Manual Conversions

The Innovative Mounts B40154 is engineered specifically for Acura Integra models originally equipped with an automatic transmission.

When converting these vehicles to a manual transmission, the factory automatic transmission mounting arrangement differs from the mounting configuration required for a hydraulic 5-speed transmission.

The B40154 addresses these mounting differences while supporting compatible B-Series and D-Series engine combinations.

Key advantages include:

• Application-specific mounting for 1994–2001 Acura Integra chassis.

• Designed for automatic-to-manual transmission conversions.

• Compatible with supported Honda B-Series and D-Series engines.

• Designed for hydraulic 5-speed manual transmissions.

• Requires a 3-bolt driver-side engine post mount.

• Precision-machined billet aluminum construction.

• Performance polyurethane bushings for improved drivetrain stability.

• Reduced excessive engine and transmission movement.

• Improved throttle response and shifting consistency.

• Multiple bushing hardness options for street and racing applications.

Precision-Machined Billet Aluminum Construction

The B40154 features billet aluminum mounting components engineered to provide strength, precise fitment, and dependable performance.

Innovative Mounts utilizes CAD/CAM design and stress analysis to develop mounting components capable of supporting performance-oriented drivetrain applications.

Billet construction provides a durable alternative to aging factory mounts while offering a distinctive appearance within the engine bay.

No-Tear Performance Polyurethane Bushings

Innovative Mounts incorporates its specialized no-tear polyurethane bushings to help reduce excessive drivetrain movement while maintaining vibration isolation appropriate for the selected bushing hardness.

Compared with worn factory rubber mounts, performance polyurethane bushings help maintain more consistent engine and transmission positioning during acceleration, deceleration, and shifting.

Benefits include:

• Reduced engine rocking under acceleration.

• Improved drivetrain stability.

• Reduced mount deflection during gear changes.

• Improved throttle response.

• Reduced wheel hop in applicable driving conditions.
