Description
The Hasport EFK4 K-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.
- Transmission: 2003–2007 Accord or 2004–2008 TSX manual transmission.
Technical features
- Dual-height mounting provides different engine positions for managing hood and ground clearance.
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.
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
- Cutting and welding are required; this is not an unmodified-chassis installation.
- K20 and K24 engine heights differ. Hood clearance depends on the selected position and the hood used.
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.
