I had stage 2 big valve avanti motorsport head. I think it was a 34x34 twin choke. It also had an electronic DCi unit. X19 wheels and many other things done to it. For a 1050cc engine i used to waste mexico 1600's and astra 2.0 gte's. On the motorway she would top out at about 114mph. I would be confident to say it was the best handling car i have ever had!
