I done a 1.7 into a Zetec s

I am glad I had the puma as a whole car to start with
As the Zetec s had a digi tacho and the puma didn't
So I had to swop everything incl" the full loom

That said me and my mate started it at 9pm and it was done by 12 the next day as we worked on it none stop

There were a few differences but if you have both cars and not just a bucket of bits you
Will be fine
