Yes and no. If you have disposable income available, your car is in good shape and want it then yes. If your not going to want to spend the massive amounts of money for all the stuff and supporting mods, then probably not. It all depends on what you can afford and want.
To me I wouldnt think its worth it, but that just because I dont want to go through the hassle of pulling the motor and all the down time. Money is never an issue if it something you want!
