Dude, to make a Soarer AWD would take major front end and tranny work... I would love to see someone pull that off...
No Soarer, Lexus SC400, SC300, come with the AWD feature.... Just traction control and that's it...Not even a true LSD either...Sorry bud....
The best you can do to your Soarer is swap and bolt up a 93-98 Toyota Supra TT Auto torsen LSD to get the dual rear wheel traction...
