Cossies are called Cossies purely because they have a 'Cosworth' Developed pinto in them! You can't really improve on that engine for the type of car, or else i'm sure you speed mad Cossie boys would do!!

I think 16v Zetecs and 1.9 CVH engines are EXACTLY in the spirit of the RS turbo, i.e. a four pot N/A granny wagon engine, specially work'ed for turbo application, but not specially developed by a factory type tuning company like Cosworth! I.E If a RST was produced today, what do you think Ford would stick in it? Take a look at the Focus RS for a clue

i don't see what the problem is? Surely Oli's 1.9 S1 is a RST? If it is not an RST, then what the hell is it Top car by the way!
