Welcome to the community.
Turbo kit's come up all the time used and for pretty good deals.
Depending on how much power you want it's going to cost a lot more than that mainly becuase of the transmission upgrades.
Look for a used Z7 kit. That turbo kit peaks out at about 500WHP. If you're looking to go a lot faster and spend a lot more look for a used T67 kit.
