The easy way is to buy the small stuff high performance spark pugs wires coil cap. You can buy a larger throttle body, or a Mopar performance computer. or get a jet chip plug in programer. You can get higher output injectors. larger exhast with headers. Better air filters and cold air intake. You can put on eletric fans get rid of the stock engine drivin Fan. You can buy higher cams larger intake man. you can bore out the cyl. walls you can mill down the block as well as the heads also known as decking. For the 5.2 you can get a 5.9 mag. heads and put them on you stock 5.2 block they will increase performance. you can change the rear end gears and that will give you more power to the wheels. Lots of stuff have fun.
