My Mates runs a 1.8 zetec on R1 carbs with emerald management. Its a really sweet setup. I think you will have to get the carbs rejetted whatever you do though.

EDIT: Just noticed you put TB!! saying that i think my mate only used carbs because he already had a set! not sure what would go into using TB, but it gets done a lot on the kit car side of thing so it can't be too difficult/expensive!
