Hi mate, from what I know there's now a fair few turbo conversions knocking about.

There was a 330bhp 2.1ltr Focus Turbo, that was running on 19'' Superleggera's, that was a lovely car, don't really know it's whereabouts now

Probably the most well known Focus Turbo is Ian Howell's one that he did himself (Racetek/Fiesta Frenzy/Area 6), that was mega quick and looks the bollox aswell, his one did 0-150mph in 19 seconds I think and went on to hit 173mph+!

HTH

BTW, get some pics up of how your car is now, do it mate, its a wicked car to start with!
