I dont like them, but whatever you want to pop for would be fine. I think they have a glass rear window which helps, but I would definitely check and see how they seal. Dont want a snake full of water.
All Horseship. there is no way a tune and bigger injectors alone will push that kind of power. Remember your 320 is only 290ish at best to the wheels. 90 horses is a long way to go with a n/a car.
Here are a couple of videos I found with guys doing top-end runs. I dont think either of them are the video you are speaking of because nobody seems to miss a shift. Can't wait till I find a place to do this with my snake. :D

I dont see it helping that much, but who knows maybe it does. Sounds a little ghetto rerouteing the hoses like that, but I am the one who put ducktape on the dash to cover up the shift light for a while.
BTW, where in Orlando are you?
I'd wouldn't be bouncing it off the limiter for the first 750 miles and a couple oil changes. Then again, it is underwarranty if anything were to go worng. Have Fun.
Sounds like a beater. Pass on it. There are better ones out there that can be had at the right price.
If your heart is set you could offer 10k, but that isn't recommeded
