I'd sell it. Unless it has some kind of meaning to hang onto it for. If you keep it, fix the 6 banger and drive it that way.

Otherwise your going to have to change alot of parts to go with a V8. Although it can be swapped with no problems, why do it? Plus its a 4 door. You will never be able to recoupe you money if you try to sell it.

Go out and find a V8 car. Then 3/4 of your problems are gone.
