In order to do it right, you would need to remove the non-turbo engine and install a turbo one. In order to make use of the increased available torque, it would also make sense to swap in the rear differential from a turbo car, along with the speedometer (or just the whole gauge cluster) in order to keep it accurate. Not the easiest job in the world, but it can be done.

Adding a turbo to a non-turbo motor is probably not going to give you the results you want unless you do a complete teardown and rebuild, changing a lot of things in the process.
