Trade in if you can.. you'd be stupid to use a T2 on a 2.0 blacktop IMO.
I'd be buying something like a stage 3 T3 (from memory.. hope that's correct!

) which has been proven to run c250bhp on 2.0 zetec turbo builds previously, so you have some headroom left and aren't running things on their limit.
