Description
The Hasport EFB1 B-Series swap mount kit provides the mounting arrangement for 88-91 Honda Civic / CRX. Match the engine, transmission and receiving-chassis configuration before selecting this kit.
Application and configuration
- Vehicle/application: 88-91 Honda Civic / CRX.
- Configuration: Cable Transmission.
Technical features
- Billet aluminum mount construction, with 6061 aluminum identified for this application. The selected insert determines the mount compliance.
Mount Insert options
- 62A Urethane: The most compliant urethane choice offered here; prioritizes isolation relative to the harder options.
- 70A Urethane: Firmer than 62A, with less insert compliance and more vibration transmission.
- 88A Urethane: Very stiff urethane for a build accepting a substantial vibration increase.
- 94A Urethane: The firmest urethane rating offered here, below solid aluminum in rigidity.
- 6061 Solid Aluminum: A rigid insert without the compliance of urethane; expect substantial noise and vibration transfer.
Choose the insert from the Mount Insert menu. A harder insert is not automatically the right choice for every build; consider cabin comfort, tires, drivetrain loading and intended use.
Installation and purchase notes
- Configured for a cable-operated B-Series clutch transmission. A hydraulic-clutch transmission needs the corresponding hydraulic-transmission mounting configuration.
Before ordering
- This is the mounting portion of the conversion, not a complete engine-swap package. Plan the compatible axles, shifter, clutch operation, wiring, fuel and cooling systems separately.
