Hasport D-Series Hydraulic Transmission Conversion Kit - 1988-1991 Honda Civic & CRX (EF)
Here's the wall a lot of EF builds hit. You find a good 92-00 D-series transmission, cheap and plentiful, and then you realize it uses a hydraulic clutch while your 88-91 Civic or CRX runs a cable. Those two don't talk to each other, and that's where the project stalls. This Hasport kit is the fix, and it solves it in the smart way: instead of converting your car over to hydraulic with a master cylinder and all the plumbing that comes with it, the lever assembly lets you actuate that hydraulic transmission's clutch using your factory EF clutch cable. Bracket it in, hook up the cable you already have, and go drive.
Which Parts Do You Need?
This comes three ways, so figure out where you're starting from before you order.
EFDHC, the complete kit, is what most people want. It includes both pieces below, the conversion brackets and the lever assembly, so you've got everything to get a 92-00 D-series hydraulic transmission mounted and actuating in your EF. If you're starting this job from scratch, buy this one and be done.
EFDHCRH, the conversion brackets, is the mounting half on its own. That's the rear bracket and the transmission bracket that let the 92-00 hydraulic transmission physically bolt into the 88-91 chassis. Get this if you've already sorted your clutch actuation another way and just need the transmission located properly.
EFDHCL, the lever assembly, is the clutch actuation half by itself. This is the piece that lets your EF clutch cable operate the hydraulic transmission's clutch. Grab this alone if your mounting is already handled and the cable-to-hydraulic problem is all that's left.
If you're not sure, the complete kit is the safe answer. Buying the halves separately only makes sense when you already know exactly which piece you're missing.
Why Running Your Stock Cable Is The Better Way
There's more than one way to get a hydraulic transmission working in a cable car, and this approach is the one that keeps things simple. Going the other direction means a clutch master cylinder, a firewall pedal conversion, running lines, and bleeding a system you just built. That's a lot of work and a lot of new failure points. Hasport's lever assembly sidesteps all of it by translating your existing cable pull into the hydraulic release, so your pedal, your cable, and your firewall stay exactly as Honda built them. Less to install, less to go wrong later, and if something ever does need attention, you're troubleshooting a cable instead of a hydraulic circuit.
What It Works With
This kit is built around 92-00 Civic D-series hydraulic clutch transmissions going into the 88-91 chassis. It also works with your stock engine mounts or with Hasport's EFSTK mount kit, so you're not forced into a particular mount setup to use it. Before ordering, confirm the transmission you've actually got in hand, especially if you bought it used, since knowing whether you're working with a hydraulic unit is the whole basis of this conversion.
Built The Way Hasport Builds Everything
Hasport designs these with CAD/CAM and machines them from 6061-T6 aircraft-quality aluminum, which is why their stuff has the reputation it does in the Honda world. Brackets that hold a transmission are not the place for guesswork or flex, and these bolt up where they should without you fighting alignment or shimming things to make it work. Hasport backs their mounts with a lifetime warranty, which tells you how they expect these to hold up.
Fits Your EF Civic Or CRX
This conversion kit fits the 1988-1991 Honda Civic and the 1988-1991 Honda CRX on the EF chassis, paired with a 92-00 Civic D-series hydraulic transmission.
Who Should Run This Conversion Kit
This is for the EF owner who wants to run a newer, better, easier-to-find D-series transmission without doing a full hydraulic clutch conversion on the car. Maybe your original transmission is worn out, maybe you found a good deal on a 92-00 unit, maybe you're building the car up and want the later gearbox. Whatever brought you here, this is the clean way to make a hydraulic transmission work with the cable clutch your car was born with. Pick the parts you need, bolt them in, and get your EF back on the road.
