ive got a 1.2 8valve too, she can do 115 no problem. Ive had all her ports etc reground and polished tuned up, etc etc by a mate who used to work as a mechanic for the btcc vauxhall team. Ive got a forced air induction kit what he made too for me. Admitedly she is the worlds fastest car, but im more than happy with what i have got!! too many police in leicestershire to go fast!!!
good luck mate
