It's an old car - you're going to spend money on it.

I have an OEM cable-clutch set up in my Syncro, which avoided all this complicated hydraulic clutch nonsense. It's a bit heavy, but not terminal.
ABF and you could probably keep your 020 gearbox... and the handling of the car.
VR6 and you're needing a replacement subframe IIRC and you'll definitely be running on the 02A gearbox.
