I want to add more power in my car and sugguests on intakes or other performance parts I can do

Check out some of the Toyota performance forums, they will have a wealth of info for you.

It depends on how much power you want to add. A simple cold air intake upgrade will give you more passing power, but a turbo kit will put you in the back seat. How big do you want to go?

the only power you will get out of an intake without anything else in conjunction with it is probably like 1 or 2 hp if you add a catback exhaust and chip it then you will gain a little bit more maybe like 5-10 hp maybe. Turbo will give you probably double the power but you wont be able to turn up the boost much prob just like 5-6 psi until you do internals and mapping. Def need to tune the whole motor really well to get the most effeciant power out of it and it will make you motor last longer. I really all comes down to how much money your willing to put down on your ride? whats your price range?
