You didn't list anything about the car, weight, gears, etc. Based on that, I'd run it and see how you like it and then upgrade after you're used to it.

It's cake to swap a turbo on that after you get the kit on. Run what you've got and see how you like it and go from there before you start swapping XYZ turbo on it.
