Product Details

Part Number: EFK5
Brand: Hasport
Insert Hardness: 62a
Drivetrain: AWD

Build your K-swapped EF chassis with the Hasport EFK5 Performance Engine Mount Kit, designed for installing a Honda K-series engine into the 1988–1991 Honda Civic and CRX. The EFK5 configuration is specifically designed for use with 2008–2013 Accord, 2009–2014 TSX, and 2012–2015 Civic Si manual transmissions.

Hasport's EFK system incorporates a dual-height mounting design and patented flip mount, giving builders greater flexibility when positioning a K20 or K24 engine. The system is engineered to optimize axle alignment while balancing ground and hood clearance for a clean, functional K-series swap.

The EFK5 is designed using CAD/CAM technology for precise fitment, strength, and durability. Multiple urethane bushing stiffness options make it suitable for everything from street-driven swaps to dedicated competition builds.

Installation Note
  • The Hasport EFK-series mount kits require cutting and welding during installation and should not be considered a completely bolt-in conversion without chassis preparation. Engine position should also be selected with hood, ground, axle, and accessory clearance in mind.
  • The Hasport EFK5 is an excellent foundation for an EF Civic or CRX K-swap using later Accord, TSX, or Civic Si transmissions, combining flexible engine positioning with the drivetrain support needed for both street and competition builds.
