Hasport K Swap Engine Mount Kit for 88-91 Civic/CRX

Hasport K Swap Engine Mount Kit – 1988–1991 Honda Civic / CRX (EF)

If you’re planning a K-swap in your EF Civic or CRX, Hasport’s EF K Swap Engine Mount Kit makes it simple. This kit drops a K20 or K24 into your chassis without guesswork. The dual-height design lets you fine-tune engine placement for proper axle angles, hood clearance, and ground clearance. Whether you’re daily-driving or building a weekend track car, this kit keeps things clean and solid.

The mounts install once you remove the factory transmission bracket, so you get a solid, predictable setup without fabricating brackets. For AWD builds, the EFKAWD option lets you run K-series CR-V or Element transmissions for more drivetrain flexibility. These mounts keep your engine where it should be, reducing movement while still letting you drive comfortably if you pick the right bushing.

Bushing Durometer Options

Pick a bushing that matches how you drive. Softer bushings mean less vibration, stiffer bushings lock the engine down and increase NVH:

• 62A: Softest. Ideal for daily drivers who want stock-like comfort.
• 70A: Good for street cars that see the occasional track day.
• 88A: Stiff. Great for track-focused setups; expect more vibration.
• 94A: Firmest. Dedicated track or competition builds; your teeth will notice it.

Hood & Fitment Notes

• K20: Fits under the stock hood using the lower mount. Upper position works best with SiR-style hoods like Carbon Trends.
• K24: Fits under a Carbon Trends-style hood using the lower mount position.
