Trust when I was young and dumb, which was not that long ago.*thats crazy* Like i was saying, I tried to do this, it is very possible, but very expensive. I swapped in the 4g63 in a 91 tsi. I like it for a while, then i wanted awd. A couple thousand dollars later, i realized it wasn't worth it. I could have saved a lot of time and money if I just saved and bought a gsx or awd tsi, in the first place. Listen to everybody on this one. Its like the same as when doing a auto to manual, they never drive the same. Speaking from to much experience. Hope this helps.
