Fardnved B-Series Traction Bar/Tie Bar
The Fardnved traction bar is designed for front subframes in 1988–1991 EF Civic and CRX chassis when running a B-Series engine swap (B16/B18/B20). Best for builders who expect higher torque and want added chassis rigidity without extensive fabrication. The bar’s primary role is to brace the front end and manage chassis flex under increased power. A clear limitation is the need to verify exact chassis and subframe configuration before purchase, as incorrect fitment can compromise performance. Best for enthusiasts seeking a direct, purpose-built brace rather than a universal solution.
88-91 Swap Shift Linkage Kit B-Series (B16/17/18)
This shift linkage kit is engineered for Honda Civic/CRX ED/EE/EF chassis undergoing a B-Series swap. It’s a strong option for immediate use or as a spare, and it’s designed to tolerate engine vibrations typical in performance setups. The kit features top-graded linkage with solid nylon bushings and a yellow zinc coating to improve durability and operability. Choose this if you value a robust, vibration-tolerant linkage that’s tailored for B-Series swaps; avoid if you require a universal fit outside EF/ED/EE chassis models.
labwork Shift Linkage Replacement
The labwork shift linkage replacement is pitched for 1988–1991 EF Civic/CRX B16/B18/B20 swaps. It emphasizes performance-oriented design with installation noted as professional recommended. Best for builders who want a straightforward replacement option with performance intent while avoiding overly exotic components. A potential limitation is that some installations may benefit from professional fitting, given the specificity of B-Series routing in EF chassis.
Bevinsee B-Series Throttle Cable Bracket
The Bevinsee throttle cable bracket is designed for B-Series engines like B16 and B18. It is aluminum, lightweight, and CNC-machined for precise fit. Best for builders who need a precise, rigid bracket that won’t add unnecessary weight and who want easy installation. Limitations include that it does not fit some GSR or LS intake manifold configurations, so verify manifold compatibility before purchasing.
ZTTW Engine Mounts For B-Series Swap
These polyurethane engine mounts replace factory rubber mounts to reduce engine movement and wheel hop in B-Series swaps. Best for drivers seeking firmer, rock-solid mounting to minimize drivetrain flex and improve throttle response. A caution is that polyurethane mounts can transmit more engine vibration into the cabin, which some users may notice during regular driving.
Buying Guide
Key considerations when choosing B-Series swap components for EF/CRX include fitment accuracy, chassis compatibility, and intended use. Here are practical questions to guide your selection:
- What chassis year and model are you swapping into? Ensure parts are listed as compatible with EF, ED, or EE as needed.
- Are you prioritizing rigidity over comfort? Polyurethane or bracing parts often reduce flex but can increase cabin vibration.
- Is this part intended for immediate use or as a long-term upgrade? Some items are replacement-type components that can be swapped gradually.
- Do you need a specific torque-handling improvement or a general upgrade? Matching the part to your power level helps avoid over- or under-engineering.
- Is professional installation recommended? Some items, especially throttle brackets or mounts, benefit from expert fitting.
Key Comparison Points
- Traction bars vs. shift linkages: Traction bars improve chassis stiffness under torque; shift linkages influence shift quality and reliability.
- Material choice: Aluminum brackets are light with precision fit; steel mounts provide strength and durability; polyurethane mounts reduce engine movement but may increase cabin vibration.
- Chassis specificity: EF/CRX-focused parts reduce fitment issues compared to universal kits.
Installation Considerations
- Follow manufacturer guidelines for torque specs and alignment.
- Inspect subframes and engine mounts for wear before installation.
- Consider professional installation for critical components like engine mounts and shift linkages to ensure proper calibration.
FAQ
- Q: Are these parts compatible with all EF Civic models? A: Most are designed for 1988–1991 EF/CRX applications, but verify exact chassis and subframe configuration before purchase.
- Q: Will polyurethane engine mounts cause excessive vibration? A: They can transmit more engine vibration into the cabin than rubber mounts; weigh comfort against reduced engine motion.
- Q: Do I need professional installation for the throttle bracket? A: It is recommended, especially if you are integrating with a non-stock intake setup or custom manifold.
- Q: Is a rear or front brace more important for a B-Series swap? A: Front braces and traction bars help control chassis flex under higher torque; consider both if your build aims for maximum rigidity.
- Q: Can I reuse original shift linkages with these kits? A: It depends on the kit; some require matching to new B-Series gear ratios and linkage geometry.
- Q: Do these parts improve daily drivability? A: Bracing and firmer mounts improve stability during spirited driving, but some components may increase cabin feel of engine vibrations.
