hate to say it but with such a new car you should have bought a 1.6 to start with.
however i believe a lot of the anciliaries like gear box zorst etc to be the same and therefore the block and head should hopefully drop straight in. if injectors dont need coding or anything else on the new engine for that matter you'll prob find its easier and no more expensive to have it remapped rather than try farting about with a 1.6 ecu and getting things coded.
