Innovative Cable-Hydro Conversion Mounts for 88-91 Civic/CRX

Innovative Mounts Conversion Engine Mount Kit for 1988-1991 Honda Civic/CRX (ED/EF)

SKU: INO-49150-60A

MFG SKU: 49150-60A

This Innovative Mounts Conversion Engine Mount Kit is designed specifically for the 1988-1991 Honda Civic and CRX (ED/EF chassis) originally equipped with a cable transmission and a D-Series engine, facilitating a swap to a B-Series engine (e.g., B16A, B17A, B18A/B/C, B20B/Z) with a hydraulic transmission. If you’re upgrading your ED/EF Civic or CRX to a more powerful B-Series setup and switching from cable to hydraulic clutch operation, this kit provides the mounts you need. Here’s what you should know to determine if it’s the right fit for your project.

What’s Included

• Mounts: Three-piece kit (engine side, transmission side, rear mount).
• Construction: Welded steel with a black finish (billet aluminum option available under different SKUs).
• Bushings: 60A durometer polyurethane (street stiffness); no-tear design to minimize vibration while enhancing rigidity.
• Hardware: Includes some mounting hardware; uses some factory/OEM bolts.
• Warranty: Lifetime warranty from Innovative Mounts against manufacturing defects.

Compatibility Details

• Vehicles: Fits 1988-1991 Honda Civic (ED) and CRX (EF) with ED/EF chassis.
• Original Setup: Intended for left-hand drive (LHD) models with a stock cable transmission and D-Series engine.
• Swap Goal: Converts to a B-Series engine (e.g., B16, B17, B18, B20) with a hydraulic manual transmission.
• Not Compatible:
• Right-hand drive (RHD) vehicles or those with stock B-Series engines (use SKU 49153 instead).
• Automatic transmissions post-swap (this is hydraulic manual only).

Fitment Requirements

• Timing Belt Post Mount: Most B-Series engines fit, but some (e.g., certain B18C variants) require a specific post mount, like the 90-93 Integra Billet Post Mount (Innovative P/N: B59350), due to taller deck heights or design differences. Check your engine’s post mount before purchasing—swapping to the correct one may be needed.
• Drivetrain: Typical axle setups include 90-93 Integra axles. Ensure the right axle uses a Prelude/Accord inner CV joint for proper transmission fitment (longer spline than Integra).
• A/C Compatibility: Retains factory A/C with the optional 88-91 Civic/CRX A/C bracket (P/N: 59180).

Performance and Design

• Purpose: Replaces soft, fluid-filled OEM mounts with stiffer, solid mounts to reduce engine movement, cut wheel hop, and improve power delivery—ideal for performance driving.
• Bushing Stiffness: The 60A bushings in this SKU offer a street-friendly balance of vibration dampening and rigidity. Upgrades to 75A (track) or 85A (race) are available under different SKUs if you need more stiffness.
• Vibration Note: Expect slightly more cabin vibration than stock, especially with higher-horsepower B-Series builds, as the fluid dampening is removed for performance gains.

Installation Considerations

• Skill Level: Professional installation by a mechanic or specialist is highly recommended due to the complexity of an engine swap and precise alignment needs.
• Non-Returnable: Once bolted down, mounts show impressions and cannot be returned or swapped—double-check fitment before installing.
• Design Features: Bolt-on, CAD/CAM-engineered for no axle bind, ensuring a clean fit if components match specs.

Is This the Right Kit for You?

• Yes, if: You have a 1988-1991 Civic/CRX (ED/EF) with a cable transmission, are swapping in a B-Series engine, and converting to a hydraulic manual transmission. You’re okay with mild vibration for better handling and want a street-oriented 60A bushing.
• No, if: Your vehicle is RHD, already has a B-Series engine stock, or you’re keeping an automatic transmission. Also, if your B-Series engine has an incompatible timing belt post mount (e.g., some B18C), you’ll need additional parts.

Quick Checklist Before Buying

1. Confirm your chassis: ED (Civic) or EF (CRX), LHD, originally D-Series with cable trans.
2. Verify your B-Series engine and source a hydraulic transmission.
3. Check your engine’s timing belt post mount—swap to a 90-93 Integra B59350 if needed.
4. Plan for axles (e.g., 90-93 Integra with Prelude/Accord inner CV on the right).
5. Decide if 60A bushings suit your driving—upgrade SKUs for track/race use.

This kit simplifies the B-Series swap for your ED/EF, offering durability and performance with clear fitment guidance—perfect for a well-planned conversion project.
