if you gotta ask about it, theres a good chance you wont be able to do it (no offense)

you have to fab up a lot of stuff, basically rebuild the whole car (engine bay/mounts, tranny, diff, axles, suspension, exhaust, shift linkage.. just to name a few things)

look at spending $5-10k if you do it yourself and have all the tools to do it.

your better off buying something like a 240sx if you really want rwd..
