around 1,000-2,500. the turbo is 200-300. you can use just the turbo but itas kinda a waste because you really cant run high boost without blowing something on a stock motor. if you want cheap and good amount of power get a 2.4 block(i have one for $100) and go to dodge and buy srt pistons/rods (300) right there $400 for basically a srt bottom end throw a stock dohc head on and the srt turbo and your looking at a almost new 2.4 srt motor for 600 and can run the stock wire harness on the older 2.4 so you dont have to deal with the srt wiring crap.
