Cars are the same except some body panels, as are the engines.
The difference you need to be looking for is whether its a mk 1 or 2
mk 1 has an alloy induction manifold and mk 2 has a plastic one.
There are small differences between mk1 and mk2 on the injectors as regards the holes in the injector and spray pattern. Although I believe they can be interchanged.
However identify your engine and identify the engine you are extracting from and swap like for like.
