"Fred got one to fit" LOL
But on a serious note there is the feasibility of fitting a 182 head to the F4RT bottom end, this would allow you to run the ktec manifold, GT series turbo, aswell as allowing you to retain the original engine mount.
The problems start when trying to squeeze the long gearbox in there and having to fabricate a suitable mount (admittedly the photos Fred posted do look as though there quite near but unless you have it in front of you you'll never know)
Other problems are the hydraulic clutch, cable operated shifter, and custom drive shafts.
All in anything is possible an RTOC lad has a 225 lump in his 5 which has a much smaller bay than a clio.
It's all about how much money your willing to spend.
