The only problem if i were to do something to it without their permission, is that as of now they are providing me with a roof over my head and food, plus they will be paying for my college assuming I don't screw up, not sure turboing my car would be the greatest idea since it would **** off the people who will be paying for me to go to school.

if i were to go ahead and do it as you stated chances are my college wouldn't be getting paid, sure I could probably work and go to college at the same time to pay for it but I would much rather not have to worry about balancing a job and college at the same time so i can concentrate on school, turbo project will just have to wait a few years or until I can convince them to change their mind i guess...
