Mtx75 is pretty much your only choice. They come in cable and hydraulic clutches. The 130ps spec 1.8 Zetec mk5 would have been a cable mtx75. The ultimate Mtx75 was fitted to the Focus Rs and it came with a Lsd as standard.

Now I do love a Zetec. And I love them even more with a blower on but they are getting slim pickings. To do it properly will cost plenty.

The st220 engine would sound great have plenty of torque and power and cost way less.

I would start with what sort of power you want and what coin you have to through at it ?
