Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

Just wondering, for people who has done this, how much is it to do a 2.0l turbo (or just a normal 2.0l) conversion, with all the stuff like suspension, strengthening the car etc...
or would it be better and more worth it to tune a 1.6? (and cheaper?)

i was lookin at diong it to my corsa was gonna cost about a grand then another grand to get 200 horses out of it...
bought a rover copur turbo for £350 instead already got 200 brake...
