Prepare to spend lots of money after the initial install... Turbos and Superchargers are a lot of work unless they are factory made. My cousin had a Camaro w/ a rebuilt engine that lived in the shop. She sold it after a couple years because she was sick of putting all her checks into a car. Now she drives one of those Supercharged Grand Prix GTPs, and loves it. No problems with it at all.
After the install just take extremely good care of your car. The a lot more maintenance with Turbos and SCs, so just be prepared to deal with all the extra maintenance and you shouldn't have many problems. I would strongly suggest getting a Turbo timer.
