how do I know if I have low or high impendance injectors. If so do I use low or high when going turbo.

If they are the stock NA injectors they are high impedance. You could also use an Ohm meter and test the injectors, high imp read 12-15 Ohms low imp are 2-3 Ohms. You can use either when you turbo an NA but if you use low impedance injectors you'll need to add a resistor pack inbetween the injectors and the ECU signal. You can use high impedance without the resister pack you'll just need something to control the injector duty cycle.

thank you, that really helped alot. What did you mean buy something to control the duty cycle, you mean like a fuel management system, piggy back, etc.

Yes. Either something like a AFC or S-AFR at minimum. AEM is if you are going over about a 550cc injector.
