I am really interested in doing this on my MK3 but the wiring side of it is stopping me from doing it. I mean do I use the original fuse box, ECU? I can build engines no probs but the wiring looks too complicated to me

Rear engine mount is a modified cvh one. Bolts straight up to a cvh box which sorts other mounts (I'm using an RST box with LSD).
Exhaust manifold - the standard st170 one is actually pretty good but a Zetec one fits, so if you can get a 4 branch then I would recommend it. I use an Ashley 4 branch that was originally on a Zetec.
I'm sure a company called Chester Sports Cars do a kit to run the st and Zetec engine on bike carbs? A friend bought the kit to put in his Zetec powered XR2 and it was very comprehensive.
A quick pic of mine
