I think looking into a turbo kit for the GA16DE is a great idea. It sounds like you have a budget. what is your budget? what do you plan on doing with the car, is it gunna be a daily driver/weekend warrior, is it gunna be a show car? etc. Other things you should look at is what kind of power you want out of the car.
Honestly i think you should turbo the GA16DE and see what kind of power you can get out of it. If you want something tried and true then you can use the Hotshot turbo kit like someone mentioned or you can find another turbo kit and give us some feedback on it. the more knowledge we have the better.
