I have a '02 Seicento Sporting I originally was going to try and shoehorn a 1.3 multijet diesel into it, however I've been told that the engine is to large to do that (correct me if this is miss-information), so it's plan two, the stock 1242cc conversion. This is where things get interesting, the stock boxes are just to damn short so what I plan on doing if getting a mk2 sporting box, bolting it onto the engine and using the final drive from the engines 'box. Has anyone tried this? & am I going completely nuts?
