Hasport B-Series Swap Mount Kit (84-87 Civic/CRX)

Planning to swap a B-Series engine into your 1984-1987 Honda Civic or CRX? The Hasport B-Series Swap Mount Kit is engineered to make this upgrade a precise, bolt-in process. Available in versions for both cable and hydraulic transmissions, and with multiple bushing stiffness options, this kit is tailored for these specific Honda models. Below, you’ll find everything you need to know to decide if these mounts are suitable for your swap and how to choose the right one for your project.

Is This Mount Kit Right for Your Swap?

To figure out if the Hasport B-Series Swap Mount Kit matches your needs, consider these key factors:

• Vehicle Compatibility: This kit is designed exclusively for:
  • 1984-1987 Honda Civic
  • 1984-1987 Honda CRX
  Note: If your car is from a different year range (e.g., 1988-1991 Civic/CRX), Hasport offers separate kits for those models. Double-check your vehicle’s year and model before proceeding.
• Engine Type: These mounts are for B-Series engines only. If you’re swapping a different engine (e.g., D-Series, H-Series, or K-Series), you’ll need a different Hasport kit. Confirm that your donor engine is a B-Series (common sources include the Integra, Civic Si, or CR-V).
• Transmission Type: B-Series engines can come with either a cable or hydraulic transmission, and the mounts must match your setup:
  • Cable Transmission: Found in older Honda models (e.g., 1989-1993 Civic Si or Integra). Uses a cable to operate the clutch.
  • Hydraulic Transmission: Common in later models (e.g., 1994-2001 Integra or 1999-2000 Civic Si). Uses hydraulic fluid for clutch operation.
  How to Check: Look at the clutch system on your donor engine/transmission. If it has a cable running from the clutch pedal to the transmission, it’s cable-operated. If it uses a hydraulic line and slave cylinder, it’s hydraulic. If you’re unsure, check the engine’s origin (e.g., a B18B1 from a 1994 Integra is hydraulic).
• Driving Goals and Bushing Options: Hasport provides five bushing stiffness levels to suit different purposes:
  • 6061 Solid Billet Aluminum: No bushings, just solid metal. Maximum stiffness for extreme racing (e.g., drag or circuit). Harsh for street use.
  • 62A (Street): Softest urethane option. Ideal for daily driving, offering comfort with reduced engine movement.
  • 70A (Race): Mid-range stiffness. Great for mixed street/track use, balancing performance and ride quality.
  • 88A (Extreme Race): Stiffer bushings for dedicated track cars. Minimizes engine movement but increases vibration.
  • 94A (Most Extreme Race): Hardest urethane option. Built for professional racing, not recommended for street driving.
  Consider This: Softer bushings (62A) reduce noise and vibration for street cars, while stiffer options (88A, 94A) improve power transfer for racing but make the ride harsher.
