can take the engine an transmission out of a 1998 supercharged bonneville and put it in my 93 bonneville, if it will work what all will i need of the other car to make it fit.

Hey, lots of people will probably throw out opinions on this. It'* been done at least a couple times before, and it'* completely possible. Especially if you go from one 92-99 Boneville body to another, engine swaps in terms of mounts are no problem at all. You'll need the transmission, all its components that go to the wheel bearings as well, the engine and its PCM, and a few electronic mods for the fuel pump to match up. Maybe you should probably get a new pump as well since your car is from 93. If you're looking for a quick answer, that'* mostly it so that you can start gathering parts. So, I'll just back off and let others come in, but I'm interested in following along since these threads almost all the time go into some great detail. Good luck!

Engine, transmission, wiring harness, PCM, axles, fuel pump, fuel lines for starters. It'll be cheaper and easier to sell yours and buy a newer one.
