there are many reasons why it might not fit or work i will give you two for a start
the ecu will be different on the two models for sure and the 1.6 one may simply not be programmable
the manifold may be different so it really wont fit.
And even if it does bolt on the turbo wont be the right size -
You may not think .2 of a litre would make little difference but 12.5 % will to the way it spools
Also the bore and stroke wont be the same (obviously ) and the compression ratio is different - the 1.6 is higher
these certainly affect how the engines rev and thus how/whether a turbo kit works
