hello i drive a mk6 1.6 zetec engined escort and have a couple of questions i need help with.....

firstly i have done the induction kit and exhaust, and now i want a bit more power from the car but without going too crazy money wise, if i was to put a throttle body form a larger car on (ie 2ltr mondeo) what will bolt on and be easy enough to fit and where is the best place to look????

also are there any other ways i can suck a bit more juice out of the engine without de-cat, or changing the exhaust at all????

all help greatly appreciated
cheers
