1981 Scirocco Mk1 engine options
 

I'm considering restoring an '81 Mk1 and I'm wondering if anyone knows what my engine options are in terms of latest year and size. It has the original 1.7 litre/8 valve in it now, but it needs work and it's got me thinking. Can I put a Mk2 engine in or, if I can't find an original Scirocco engine could I put a Golf or Jetta unit in without much difficulty? Thanks.
