2.2 Eco-Tec = 150bhp
2.0 Red Top = 150bhp
Theres loads more tuning stuff available for the Red Top, but there is also a very good supercharger conversion available from Courtenay or Regal for the 2.2. The Courtenay Sport website has some vids of this very conversion. But i've said before and i'll say it again, go for the 2.5 V6 for £300, maybe £500 for everything you need
