I recently purchased a 2004 RX8 A/T. I don't know much about cars, so I do have a few questions. I've been on the internet all night trying to find answers but they elude me.

1: I read that the M/T rx8 pushes 238 HP, while the A/T hits about 197. I also somewhere read that rx8's are not performing as high as they are listed, so would that put me at about 150hp?

2: I would like to upgrade my car with things such as turbos and whatnot, but I cannot find any places to purchase turbo kits, and the ones I do find are for M/T only. Is there nothing I can do to significantly increase my power? And if there is, how much power would I gain?

 

this would be a good place to start reading
