My name starts with M

Lots of thanks for all the great replies!!

I had a 1986 leone coupe with 5 speed manual FWD, it was my first car. Gave it to my dad, he wants to convert it to 4WD (he had a 4WD leone pickup that he liked very much like 20 something years ago so for him its a real dreamy car and i think its an awesome project since it will bring that subaru back to life). Wanted to know: 1) Could we swap parts including engine from a newer mid 2000's to start of 2010's Impreza? 2) What do we need to put in and/or swap to make it old 4WD or new all time AWD? Would realy love to make that dream come true! Lots of thanks to the Subaru gurus
