Hi all, I swapped out the old 1600 for a 2332cc, what do you think...should I inform DVLA about the new engine? There is a section for it on the registration certificate "Section 7: Changes to Vehicle" where you can update the engine number and CC rating, does anyone know if this is a legal requirement or not? Because we are tax free I assume the engine size doesn't come into it? Any other implications, for or against?
