i have a 2g nt talon, i want to replace my engine with a high performance one, (preferably a turbo one) but i dont know what i need to do or what i need to find out. i would apreciate any help.

Well, you have a lot to read about here then :thumbsup. There's some good news and some bad news. The bad news is that there isn't a cost effective "high performance" engine that can be swapped into our cars. The 4g63 turbo engine will fit, but will take a lot of fabrication and lots and lots of money to make work since it is a mitsu engine and we have chrysler engines. The good news is that the engine that you have in your car can be made very fast for less money than an engine swap. Check out the turbo/nitrous sections for info on aftermarket turbo and nitrous kits. Read through the forum as much as you can. There is enough information here to learn to do just about anything you can do to your car. Welcome, B.T.W.

Im not a rookie n e more finally!!! but what u should read up on is turbo charging you're car if u want to increase horsepower instantly. Nos is a temporary solver 2. Check out some of the hahn stage kits and those star kits as well
