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

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

Transform your EF Civic or CRX with the Hasport K Swap Engine Mount Kit, engineered to make installing a K-Series engine a true bolt-in upgrade. Designed specifically for the 1988-1991 Honda Civic and CRX chassis, this mount kit features Hasport’s innovative dual-height mounting system, allowing you to fine-tune engine placement for ideal axle geometry, improved ground clearance, and proper hood fitment. Whether you’re building a street machine or a dedicated track weapon, this kit delivers unmatched precision, strength, and reliability.

Once the factory transmission bracket is removed from the frame rail, the Hasport mounts drop into place—making your K swap cleaner, stronger, and more efficient. For builders looking to take things further, the EFKAWD option supports AWD and FWD K-Series transmissions from the CR-V and Honda Element, giving you even more drivetrain possibilities. With a perfect blend of durability and performance, these mounts set the standard for K-swap hardware.

Bushing Durometer Options

Hasport mounts are available in multiple urethane durometers, allowing you to tailor the balance between ride comfort and performance:

• 62A: Softest option, ideal for daily drivers seeking stock-like comfort with minimal vibration transfer.
• 70A: A balanced option for street performance and occasional track use, offering a mix of compliance and control.
• 88A: A stiffer durometer designed for track-focused setups, maximizing engine stability while increasing vibration transfer.
• 94A: The firmest option, engineered for dedicated track or competition vehicles where maximum performance outweighs comfort.

Hood & Fitment Notes

• K20: Fits under the stock hood using the lower mount position. For maximum ground clearance, the upper position works best when paired with an SiR-style hood (such as the Carbon Trends hood available from Hush Performance).
• K24: Fits under the Carbon Trends hood using the lower setting.
