you said i belive. now when i read something on a block i don't say i belive it says, i say "my block says....". i do read you need to learn how to talk/spell.
first off you don't have a 1.6 its a 1.5, second off, the 1.6 plug wire don't fit correctly either, they are a b***h to find and expensive but you can find the correct ones for the VX motor. now i don't know about the disi, they might be the same part number might not im not sure, but you don't have a 1.6 motor its a 1.5.
it will take 1.5 parts you just have to find the correct parts for it.
