Purp_maro1999

I have a a4 1999 camaro rs. The car is in perfect condition, it just lacks a little in the performance department. I wanna put in a carbed 6.0. I know I need a kmember, fuel pump, and radiator. But does the speedo have to be changed? Fuel lines? And what about the stock exhaust and power steering lines and such?
And please don't tell me to buy a new car, I have no desire to sell my existing car.
