Thanks for your replies everyone. Ok so the general opinion seems to be that it's possible to improve performance but no point due to cost and hassle. Can I ask if anyone knows how much it would cost to - taking the first example given - put an ST engine in the 1.25, and all other necessary replacements to go with the engine? Are we talking over £5,000 or something like that? Otherwise I'm not sure why people are saying that it wouldn't make financial sense to do so - is it not better to pay a few grand to upgrade current vehicle rather than trade in and lose money on both trade in value and more expensive newer car?
The car that I inherited (long story), is a 12 plate Fiesta 1.25 with 20,000 on the clock. I've just started a new job where I will now only be doing 3-5,000 miles a year. I like everything about the Fiesta except the power and intend to hang on to this car 5-10 years if I can so can someone explain how it'd be cheaper to change car than alter current one? Are the costs of change and higher insurance costs really that high? Again, sorry for not having a clue but I'm glad to be learning
I think we have given you the best advice based on our experience etc, so we have told you its a waste of time trying to get more power out of the 1.25, and you would have to do an engine swap
"engine swop" is easy to say, or to write, but its a little bit harder to do, there is a whole lot more to it than you 1st expect, and you need a lot more from the donor car than you might think at first - you might as well buy a whole ST to get the parts you need (i cant be bothered listing everything you need - its a long list and a lot more than just the engine components)
If you can't do the engine swap yourself you will have to get someone who knows what they are doing to bo it, and will probably have to pay them
Then, the insurance will be even more than an ST, you may not be able to get it insured, and it may not drive/ run as well as a factory/ bought ST
You do what you like, but you would be going to a lot of hassle/ spending a lot of time/ money on a car that probably would not even be as good as a bought ST - a pointless exercise in my opinion - but if thats what you really want to do - its your choice, we are only offering advice
You seem to be attached to your car - We can all get attached to our cars but at the end of the day they are really just are just lumps of metal and plastic, - now, if you could have any car, money-no-object, what would you have?
