hello, i have a 2006 1.25 fiesta, and i am wanting to put a bigger engine in it? i have read a few post and most people say just buy a st but seen as tho im 17 the insurance slams me as it is, i have been told a focus st170 engine will go in an the mounts are the same? i do have a st170 and just wanted to know if this would go in? before i start breaking it for parts and end up selling the bits i need could you let me know the best solution for this as i want more power
