Upgrade your Honda or Acura with the Innovative Mounts 29550 Steel H-Series Conversion Engine Mount Kit, specifically engineered for installing a Honda H-Series engine and manual transmission into compatible 1992–1995 Honda Civic and 1994–2001 Acura Integra chassis.

Designed for enthusiasts looking to take advantage of the increased displacement and performance potential of Honda's H-Series engines, this three-piece conversion kit provides the primary engine and transmission mounting components required to complete an H-Series drivetrain swap.

The Innovative Mounts 29550 is compatible with supported Honda Civic EG/EH/EJ and Acura Integra DC/DB chassis originally equipped with either a manual or automatic transmission. This makes it an excellent option for traditional H22 engine swaps as well as automatic-to-manual transmission conversions.

Unlike factory rubber or hydraulic engine mounts, the Innovative Mounts 29550 utilizes heavy-duty steel mounting assemblies combined with performance polyurethane bushings. This construction helps reduce excessive drivetrain movement during acceleration, deceleration, and shifting while maintaining consistent engine and transmission positioning.

Each mount features Innovative Mounts' no-tear polyurethane bushing design, engineered to withstand the demands of performance driving while providing vibration isolation appropriate to the selected bushing hardness.

The kit is CAD/CAM designed and stress analyzed to provide accurate engine positioning, reliable drivetrain support, and proper axle alignment when installed with the required supporting components.

Engine Swap Compatibility

The Innovative Mounts 29550 is designed for compatible Honda H-Series engine swaps using a manual transmission.

Popular applications include H22-powered Civic and Integra builds, particularly those using engines from the Honda Prelude.

The mounting system is engineered to position the drivetrain correctly within the supported chassis while accommodating compatible factory air conditioning and power steering components.

Manual and Automatic-to-Manual Applications

The 29550 supports both factory manual-transmission chassis and factory automatic-transmission chassis being converted to an H-Series manual drivetrain.

For automatic-to-manual conversions, additional components such as a manual pedal assembly, clutch hydraulic system, shifter assembly, and associated conversion hardware are required.

Required Engine Post and Rear Bracket

Installation requires two important components that must be verified before beginning the swap:

Honda 11910-P13-000: H-Series timing belt-side engine post from a compatible 1992–2001 Honda Prelude application.

Rear Engine T-Bracket: A compatible bracket from a 1990–1993 Honda Accord DX/LX or 1992–1996 Honda Prelude V6 application.

The factory Accord EX rear bracket is not compatible with this mounting configuration.

Innovative Mounts offers the 59630 rear mounting bracket as an alternative to sourcing the appropriate factory component.

Polyurethane Bushing Options

The Innovative Mounts 29550 is available in three polyurethane bushing hardness configurations:

• 75A: Street and performance driving.

• 85A: Track-oriented and high-performance applications.

• 95A: Dedicated competition applications requiring maximum drivetrain rigidity.

Whether you're building a naturally aspirated H22-powered Civic, a turbocharged Integra, or completing an automatic-to-manual H-Series conversion, the Innovative Mounts 29550 provides a durable foundation for your engine swap.
