I have never done one, but can't see why it would take longer than the 2 to 3 hours it would take with any other standard RWD car. I would get a tranny jack from Harbor Freight...

Definitely NOT 6-9 hours. If you're taking it out with only 2 guys make sure you PREP the area you're working in! Set everything off to the side and make sure you know where everything is. It'll make putting it back in EASY and PAINLESS!
