1989-1991 Honda Civic/CRX EFV3 Cable to hydro conversion

About Our Kits
We’ve been in the cable-to-hydraulic conversion business since 2009. Our kits were inspired by DIY methods shared on popular tuning forums like Honda-Tech. Originally, we adapted 1992-1995 Civic clutch masters using custom mounts because cables would stretch, break, or fail when swapping to hydraulic transmissions.
Back then, retrofitting, cutting, and modifying were normal. Our goal was always simple: make older chassis compatible with newer hydraulic transmissions without breaking cables or limiting transmission choice.
What made us different:
- In 2009, we created a bolt-on conversion, allowing buyers to source only the remaining parts.
- We mount the clutch master inside the car, unlike most OEM setups in the engine bay.
- Over the years, we switched to Wilwood masters for improved hose routing and pedal feel.
- Some modifications are necessary: the driver-side vent and fresh air duct cannot be reused. Heater and A/C remain functional.
Important Notes
- Most kits do not include a standard slave cylinder. Only two specific kits (Option 3: B-Series slave, and Option 4: D-Series conversion) include a standard hydraulic slave.
- Some kits include a hydraulic release bearing, which functions like a slave for twin or triple-disc clutches.
- The kit works with any transmission that uses a hydraulic slave, provided the correct slave or release bearing is used.

3. EFV3, Wilwood Master, Billet Reservoir, B-Series Slave, Adapter & Linkage (Includes Standard Slave)

5B. EFV3, 3/4" Wilwood Master, Billet Reservoir, Clutch Line & B-Series Bearing
Complete kit with Clutch Masters hydraulic release bearing. Ideal for twin or triple-disc clutches. Pedal feel will be heavier than stock due to larger master and heavy pressure plates.

Same as 5B but for K-Series applications. Proper 3/4" master ensures complete clutch disengagement with heavy-duty pressure plates.
