Hi guys, please don't slate me for this question. . How practical is it to fit a zetec 1.3 into a streetka as a replacement to a 1.6 ? I'm asking for the money and running costs factor. More economy, cheaper road tax etc. How would insurance be effected? Would that bring the streetka insurance down or will it be classified as modified, even if going down in cc's? If I change the engine capacity on log book does that trigger bells on the insurance data base? I'm asking this hoping just to save a few £££s, vehicle performance is not an issue here. Many thanks in advance for help and advice.
