What Turbo's would work best for a fairly mild fuel injected twin turbo 440 in a 73 Roadrunner street car? I'm looking to make 600-800 rwhp. I prefer cheap or junkyard as this is my first turbo experience. I am planning on making my own log style ex manifold and putting one turbo in the area the battery was in and the other one in about the same area on the passenger side in the burp tank area. I am not planning to start this project until winter but would like to start looking for the turbo's/parts now so I am ready when the fun starts
