if in a year or so, i want to get a car with a bigger engine or put a bigger engine in my car, would it be much work. just say that if i removed my 1.2 engine. would a 1.8 engine fit in without much work.
It would physically fit the shell, but you need to uprate everything else to match, the g/box, the suspension, the exhaust the electrics - ECU etc, therefore the the locks as well etc etc!
