Its not that hard to convert a 4AGE to RWD, If you are mechanically handy it is not that bad. It is even easier if you are doing the conversion to an AE71/AE86 as its a pretty straight foward bolt in. That said there is a lot of effort that goes into modifying a car, But you can do it quite cheap if you want. You learn a lot of stuff on the way too, Nothing like getting your hands dirty..
