Those Innovative Mounts Conversion kits are just that; conversion kits to allow a car that originally came equipped with a cable transmission to utilize a newer hydraulic transmission. Hence the name, "cable to hydro". The kits are just a bolt-on mechanical linkage that allows the older cars' clutch cables to actuate the hydraulic operated transmission. I will tell you right now, these will be of no use to you for what you desire.

As far as I know, there is no readily available bolt-on kit to go backwards. That is, hydro to cable.

I know that with the B-series transmissions, it is possible to swap gear sets from the newer hydraulic B-series transmission to the 90-93 YS1 (Integra) cable transmission.

The 90-93 YS1 is the ONLY B-series cable transmission that can accept the newer hydraulic gear sets. This is because the other B-series cable transmissions use a smaller diameter input shaft and a smaller housing. The YS1 transmission is the only cable transmission with the same size diameter input shaft and housing as the newer hydraulic B-series transmissions.

That being said, let me make some things clear to you:
-Your car is operated using a hydraulic transmission (you already know this).
-Make things easy (and less expensive) on yourself and KEEP IT THIS WAY.
-It will not be a simple transmission swap. You will need to mess with the internals.

You will be better off trying to install the HF gear set into your original VX transmission and using that in your car.

I'm not sure it's even possible on the D-series trannys, as I've been a B-series guy the majority of my Honda stint. I would think that it is possible to swap the internals from the cable HF to the hydro VX tranny. I'm not sure what is required, though. You will need to do some research to see what is needed to make this happen.

You might also be better off doing just a final drive (FD) swap to your current transmission. You'd have to go aftermarket if you go this route, as the HF and VX both have a 3.25 FD (the lowest of all the D-series (As far as i know)).

To be honest, after comparing the gearing of the two transmissions, I don't think it will be worth the money (unless you can get everything DIRT cheap and do the work yourself). The two transmissions are relatively comparable, with the VX being 3-5mph lower in gears 3 and 4. Gear 5 is essentially identical (close enough to it). You'd be better off getting a different aftermarket final drive, but good luck finding a lower one.
