Hiya, as it says in my sig at the bottom, i have a 1.8 sport Mk 4 Astra. I am guessing, by the way it goes, I have got the 115 brake engine. Now, in the Vectra 1.8 sri its a 130 brake engine. You can probably guess the rest, but, how do I get my Astra to 130 brake. My guess would be slightly altered Camshaft profiles + a different map or even different ecu. I don't find it underpowered, but, a few more gee gees always comes in handy.
