A 1987 mk2 Scirocco has come up for sale near me at a very very tempting price

Could anyone help me with these questions please?
1. 1.8 8v injection engine, is this the golf mk1 engine or mk2 engine?
2. was k-jet or digi or something else used in 1987?
3. brakes and suspension, golf mk1 or mk2 parts?
4. interior, will 3dr mk2 doorcards fit?
Thanks in advance
