Description
The Hasport EFSTK D-Series engine mount kit is intended for 88-91 Honda Civic / CRX and provides the replacement mounting arrangement for this application. Insert choice changes the compliance of the mount; it does not change the required fitment.
Application and configuration
- Vehicle/application: 88-91 Honda Civic / CRX.
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
- For the original D-Series/manual-transmission mounting arrangement, including supported SOHC/DOHC ZC applications. Not for the AWD Civic Wagon.
Before ordering
- A later D-Series engine or hydraulic transmission conversion requires the corresponding block-bracket and clutch-conversion hardware.
