Is it possible to get a turbo charger for my RX8 without a big chance of messing up any wiring? If yes, what kind would fit good with it? Help me...

yes, but ask me again in 1-2 years.

Check the Tech Performance and Aftermarket sections in this site. There have been many attempts in putting a working turbo kit for our car, but none of them have finished it 100%. By 100%, I mean the kits is ready for mass production and can be ordered from certain dealers.

IMO, the (clear) successful attempt in making our car faster has only been Charles Hill's nitrous installation. Even the Canzoomer is getting mixed reviews right now.
