you will need alot of work and $$$ todo this
parts, engineering, paper work and legalities.
If you want a 4WD toyota then get a GT4.
But honnestly the only real market rwd cars you want are made by nissan these days everyone else has gone soft and changed to fwd.
The AE111 Might look good but leave it as it is. It was designed FWD. Take a look at the Integra its fwd and is pretty quick on the track. Making it fast is upto you and how well you can drive not what the drive train is.
