Hey Jazz, don't want to rain on your parade but if you are contemplating this modification for your 126 to use it on UK's roads there are allot of rules and regulations that you have to follow, The car will probably have to go through the VOSA SVA test so its not as simple as "dropping a V4 in" You will also need to upgrade the braking system

My advice would be Do your Homework before you start cutting the car up, If you can meet the criteria that is specified by VOSA/DVLA and have the skills, I wish you the best of luck
